College of Agriculture & Natural Resources Department of Horticulture
Horticulture is the science and art of the development, sustainable production, marketing and use of high-value, intensively cultivated food and ornamental plants.
Horticultural crops are diverse, including:
- Annual and perennial species,
- Fruits and vegetables,
- Decorative indoor plants and
- Landscape plants.
Horticulture also contributes to quality of life, and the beauty, sustainability and rehabilitation of our environment and the human condition.
Plants, crops and green spaces sustain and enrich our lives by providing nutritious food, enhancing the beauty of our homes and communities and reducing our carbon footprint.
Horticulture & Green Careers
Practitioners of horticulture are as diverse as the crops that make up the industry and the discipline. They include a wide array of individuals and groups who farm, landscape, garden, research, advise and enjoy the bounty of horticultural plants for their nourishment, health benefits and aesthetics.
Michigan is among the top 10 states in terms of employment in the green industry.
Michigan ranks third in floriculture/greenhouse production in the United States, with wholesale crops valued at over $400 million. Plant bedding/annual garden plants account for over half of those sales &ndash leading the U.S.
Environmental horticulture provides a range of green career paths including in greenhouse production, wholesale brokers, commercial nurseries, garden centers, florists and landscape design and construction firms. There are also green jobs in private and community gardens, municipal parks and state or national reserves.
The Student Horticulture Association is an opportunity for students to connect, network and get involved on campus.

Applications of RAPD Marker in Plants | Genetics
In this article we will discuss about the applications of RAPD marker in plants. Also learn about its demerits.
1. RAPD is used to distinguish between variety is based on difference in DNA sequence. RAPD have been used to identify nearly 15 commercial sunflower varieties. The new bean varieties (Phaseolus vulgaris) which are difficult to distinguish based on mor­phological trait have been used as ideal candidate for the application of RAPD marker methods when DNA was extracted from each varieties. The 12 samples were analysed using 60 primers.
This produced 296 markers and that could be scored. Al­most 85% similarity was predicted. For example, DNA from plant allows the ampli­fication of sequences a, c, d but not b. This indicates that in plant 1, primer sites for the primers used not found at sequence b. Similarly, a DNA sequence alternation at one of the primer binding site (priming) for a sequence ‘a’ has prevent it from being amplified when DNA from plant 2 is used.
RAPD have been extensively used for number of horticultural crops in variety iden­tification, genetic purity and sex determination. A specific RAPD marker has been used to select for high and low β-glucan content between barley varieties.
2. RAPD markers are employed in the construction of genetic maps. Genetic maps of several plants including model plant Arabidopsis and tobacco have been constructed. RAPD markers have been used to construct 15 linkage groups in coffee. Both genomic and chloroplast DNA provided the source of probes.
RAPD markers are used for the selection of segregating populations more or less indirectly, during plant breeding. These markers also accelerate back crossing process and allow the selection of individually with more of recurrent genome at each generation facilitate breeding programme to be completed within few generations.
3. RAPD molecular marker used in the direct selection of desirable trait. Molecular marker linked to the trait of interest can be screened for at any stage in the breeding programme.
4. RAPD and other molecular markers have great value in the selection for desirable trait in long-lived species which takes long time for maturity and show phenotypic character. For example, avacado (Persea americana) fruit quality can be assessed in seedling itself using RAPD molecular marker.
5. RAPD markers have been used to identify several disease resistant genes in plants. The rp94 gene is responsible for resistance to stem rust (Puccinia gramnis) in barley. RAPD markers identified to link to this gene. Similarly, RAPD markers linked to heat smut resistance gene have been characterized. Controlling of height in barley plant by specific gene has been used to locate dwarfism gene by RAPD marker.
6. In tissue culture work, somatic hybrids involving protoplast fusion requires thorough screening. However, screening of somatic hybrid is cumbersome. Therefore, RAPD markers can be exploited in identifying somatic hybrids. RAPD analysis provides an important tool for the characterization of biodiversity.
Identification of areas rich in endemic genotypes helps in habitat conservative and prevents species extinction. Molecular analysis of genetic diversity using RAPD or RFLP in plant genetic germplasm collection facilitate better management especially space and resources are serious constraints.
RAPD analysis has been used for the identification of duplicates in germplasm. These duplicates are then discarded once no morphological differences were detected. RAPD analysis has been implicated in the analysis of rice genome collections held at the International Rice Research Institute, Phillipines.
Genetic diversity was carried out in a set a 63 tetraploid wheat genotype. Which comprises 24 duran land races, 18 duran cultivars and nine diococcum cultivars, two wild tetraploid species? The duran and dicoccum wheat genotypes are part of the germplasm used in Indian tetraploid wheat breeding programme.
RAPD scoring analysis reveals 78% were polymorphic in different categories of Indian tetraploid wheat. These indicate that RAPD diversity data can be used in breeding improved cultivars and maintaining genetic diversity in germplasm. Similarly RAPD markers were generated from 6 groups of 23 varieties of Tibetian barley. Nearly 23 RAPD and 29 genes loci were identified on 72 chromosomes.
RAPD have also been used in variety identification and purity in grain processing in food industry. For example, particular duran variety of wheat is used in the prepara­tion of food products. Contamination of other variety can be identified by using these molecular markers.
1. Constraints about reproducibility of results.
2. Since RAPD markers are dominant, only half the genetic informations are co-domi­nant markers.
Materials and Methods
Plant material and cultural conditions.
Two experiments were conducted, a greenhouse and growth chamber experiment. The first experiment used 1.5-year-old seedlings of ‘Volkamer’ lemon (Citrus volkameriana) from late Aug. to mid-Oct. 2009. The trees were grown in an unshaded greenhouse under a natural photoperiod with an average temperature of 29 ± 7 °C and relative humidity from 70% to 95%. All trees were grown in 2.65-L Citra-pots (CPOT-5H Stuewe and Sons, Tangent, OR) using a commercial potting mix composed of peat, pine bark, perlite, and vermiculite (Fafard 2B Mix Conrad Fafard, Agawam, MA). Trees were ≈40 cm tall at the start of the experiment with multiple branches. Five single-tree replicates were used for each PGR treatment (Table 1), and untreated trees served as controls. Trees with very young “feather” flush (i.e., recently broken buds with new growth ≈1–2 cm in length and immature leaves just beginning to unfold) were selected for use in the experiment. The seedlings had never been treated with systemic insecticides and the last treatment with contact insecticides was greater than 1 year before PGR treatment.
Active ingredient chemical name, trade name, manufacturer, and rate of plant growth regulators used to study the effects of applications to Citrus sp. on the reproductive biology of the asian citrus psyllid.
The second experiment was conducted from Jan. to Feb. 2010 and was carried out in a custom-built walk-in growth chamber (Mechanical Refrigeration, Winter Haven, FL) to provide conditions suitable for vegetative growth. The growth chamber was maintained at 28/21 °C day/night temperature with a 14-h photoperiod and a light intensity of 900 μmol·m −2 ·s −1 photosynthetically active radiation. Relative humidity was not controlled and averaged 50% to 70%. PGR treatments were the same as those used in the greenhouse study (Table 1) however, an additional water + adjuvant control was included. For this study, eight 1-year-old ‘Valencia’ sweet orange trees on ‘Kuharske Carrizo’ citrange (C. sinensis × Poncirus trifoliata) rootstock were used for each treatment. All plants were grown in 2.65-L Citra-pots using the potting media described previously and were ≈70 cm tall at the start of the experiments. The plants had never been treated with insecticides.
Growth regulators and application techniques.
The PGR formulations used in the experiments are listed in Table 1. These PGRs were selected because they have been previously shown to be efficacious on citrus (prohexadione calcium and paclobutrazol) or other tree fruit species. All products were applied as foliar sprays to runoff, coating upper and lower leaf surfaces, using a 1-L handheld pump-up sprayer. The soil surface was covered with a cardboard shield during application and was left in place until the products dried to avoid soil contamination and potential root uptake. All sprays included a non-ionic surfactant (Induce® Helena Chemical Co., Collierville, TN) at 2.5 mL·L −1 . The prohexadione calcium sprays also included 5 mL·L −1 of 5% citric acid to aid in product uptake as per the manufacturer's recommendations. Product application rates were selected based on previously published data for citrus (prohexadione calcium and paclobutrazol) or by selecting a recommended label rate for tree use.
In both experiments, the total shoot length (sum of the main stem and all lateral branches) of each tree was measured before PGR application and again 32 d later (after ACP removal). The percent increase in total shoot length was calculated by dividing the difference between the final and initial total shoot length measurements by the initial total shoot length and multiplying the result by 100.
Seven days after PGR application, a randomly selected pair (one male, one female) of ACP from a colony reared on ‘Volkamer’ lemon seedlings or ‘Valencia’ sweet orange trees maintained within psyllid-proof screen enclosures in the greenhouse previously described was caged on each tree. The cages were constructed from a sheet of polyethylene monofilament woven screen with a hole size of 0.266 × 0.818 mm, which was loosely draped over each tree and secured around the trunk. The number of eggs laid on each plant was counted at 3-d intervals for 21 d. As development of the eggs and then nymphs occurred, the number of nymphs and adults was also counted. Survivorship of nymphs to the adult stage was assessed by dividing the total number of adults after 21 d (less the two original adults) by the total number of nymphs. Adults were then collected and weighed to determine adult body mass.
To determine if the PGR treatments affected photosynthesis, and thus potentially reduced phloem sap carbohydrate content, instantaneous net CO2 assimilation was measured in the growth chamber experiment on one recently expanded mature leaf on each plant per treatment at 15, 25, and 33 d after treatment using a portable photosynthesis system (LI-6400XT LI-COR, Lincoln, NE) with a 6-cm 2 broadleaf chamber. The chamber was equipped with an external light-emitting diode light source (6400-02B LI-COR) set to match the ambient light level (900 μmol·m −2 ·s −1 ). In addition, to determine if there were any PGR-induced differences in the nutritional status of the plants, all leaves were removed from each plant at the end of the growth chamber study and sent to a commercial laboratory for complete nutrient analysis (nitrogen, phosphorus, potassium, magnesium, calcium, sulfur, boron, zinc, manganese, iron, and copper Waters Agricultural Laboratories, Camilla Park, GA).
ACP egg counts and adult body weights were natural log-transformed and percent ACP survivorship data were arcsine-transformed to ensure normality, linearity, and homoscedasticity. Differences between treatment means were tested for significance with Tukey's honestly significant difference ( hsd ) test (P = 0.05). Plant nutrient and photosynthesis data and arcsine-transformed percent increase in tree growth data were subjected to one-way analysis of variance. Differences between treatment means were tested for significance with Tukey's hsd test (P = 0.05). All analyses were conducted using SAS (Version 9.2 SAS Institute, Cary, NC).

Uses of Auxins in Agriculture and Horticulture (With Economic Importance)
The below mentioned article will highlight the eleven uses of auxins in the field of agriculture and horticulture.
They are: (1) Apical Dominance (2) Meristematic Activity (3) Rooting (4) Parthenocarpic or Seedless Fruits (5) Flowering in Pineapple (6) Prevention of Premature Fall of Fruits (7) Prevention of Sprouting of Potatoes (8) Weed Killing (9) Control of Lodging (10) Differentiation of Xylem and Phloem and (11) Sex Expression.
(1) Apical Dominance:
The auxins greatly influence the development of plant form and structure. It has long been known that while the main shoot of a plant is growing, its lateral buds are inhibited. If, however, the bud at the apex is cut off, the lateral buds begin to develop. It has been postulated that an inhibiting substance diffuses from the growing bud to the tissue below it.
With the advent of synthetic growth substances this theory was corroborated. When the apical bud was removed from the shoot and a small quantity of Indoleacetic acid was applied to the stump the lateral buds did not develop. The Indoleacetic acid was found to possess the power to inhibit lateral growth. Removal of plant apices is commonly practiced in lawns and gardens to develop hedges. The principle behind such practice is to eliminate apical dominance.
(2) Meristematic Activity:
Auxin affects the meristematic activity of cells other than those involved in tumor and callus production. Auxin produced in the apical bud stimulates and regulates the activity of the cambium in woody plants. It seems probable that the resumption of cambial growth in the spring is due to auxin produced by the buds in this season. Cambial growth may also be induced by the artificial application of auxin.
Propagation of plants by vegetative means is quite commonly practiced in horticulture. Several experiments performed on a great variety of plants showed that auxin applications are generally beneficial in bringing about the rooting of cuttings. The process, known as vegetative propagation, is extremely useful to the horticulturists, for by means of it a great many genetically identical plants may be made from a single individual, and a desired genetic pattern, as in a variety of apple, seedless orange, or a rose of a new colour, may be preserved from generation to generation.
In practice, the ‘cutting’ is usually a twig with a few leaves on it, but sometimes leaves, pieces of stem or root, or even bulb scales may be used to start a new plant. Auxin treated cuttings generally root more rapidly than untreated ones, and the roots are more abundant and stronger. Dipping cutting into auxin solutions or powders has become a standard horticultural practice in advanced countries, and there are, in the market today dozens of preparations for the said purpose. The same ability to promote root growth is also possessed by ethylene.
The most widely used of the synthetic auxins for this purpose is Indolebutyric acid (IBA). It is used either alone or in combination with other auxins such as Naphthalene acetic acid (NAA). Recently attention has been called to the effectiveness of some of the chlorinated phenoxy acids.
(4) Parthenocarpic or Seedless Fruits:
Another property of auxins that has grown to economic importance is their ability, when applied to the flowers of certain species, to initiate development of fruit without pollination. Because of the difficulty of obtaining satisfactory pollination in some plants as well as to improve the quality and market value of the fruits auxin treatment in the form of sprays or aerosol is used.
Fruits so induced are usually, seedless so besides increasing yields, auxin treatments may make possible the development of new seedless varieties. Naphthalene acetic acid (NAA) and Naphthoxyacetic acid (NOXA) have been successfully used in many plants to induce parthenocarpy.
(5) Flowering in Pineapple:
In the raising of pineapples there is great difficulty in obtaining satisfactory fertilization and development of the fruit. But here the problem is to obtain flowering at the proper time. The size to which the fruit develops is directly dependent on the number of leaves on the plant at the time of flowering. J. Van Overbeek, found in Cabezena variety of pineapple, which flowers poorly when left to itself, can be made to flower at any time of the year by a single application of an auxin.
Naphthaleneacetic acid or 2, 4-Dichlorophenoxyacctic acid. We, therefore, have the interesting possibility of producing uniform fruits of a selected size by applying the auxin to each plant when it has the appropriate number of leaves.
(6) Prevention of Premature Fall of Fruits:
In U.S.A. and Russia particularly, growers of citrus, apples and pears use large amounts of auxins for the prevention of premature fall of fruits. From a fourth to half of the entire crop may be lost because the fruit falls before it has matured or developed good colour. Thus the grower must either harvest before the best quality is attained or else, risk a heavy fall.
Auxin sprays proved highly successful, and now growers can obtain reasonable assurance against loss to their apple and pear crops by using these auxins. Naphthaleneacetic acid has given satisfactory results in apples and pears where as in case of citrus, 2, 4-Dichlorophenoxyacetic acid is more successful.
(7) Prevention of Sprouting of Potatoes:
Still another commercial application of auxins takes advantage of their growth inhibiting ability. The methylester of Napthaleneacetic acid prevents the sprouting of potatoes in storage thus the tubers will keep longer, even at warm temperatures.
(8) Weed Killing:
2, 4-D (2, 4-Dichlorophenoxyacetic acid) has received wide acclaim as a weed-killer, for when sprayed on plants it kills the broadleaved dicotyledons, while sparing the grasses. Under favourable circumstances it can be used to keep sugar cane fields, corn and wheat fields or lawns free from most common weeds without laborious hoeing or weeding. Recent experiments indicate that in the plants affected by 2, 4-D there is a temporary sharp increase in the rate of metabolism.
The sprayed plant is not only injured where the chemical comes in contact with it, but is stimulated to burn up its reserve food supply. As a consequence it starves to death. In smaller concentrations 2, 4-D can also be used for most of the applications of auxins.
(9) Control of Lodging:
In some plants when the crop is ripe and there is heavy rain accompanied by strong winds, the plants bend as a result of which the ear (inflorescence) gets submerged in water and decays. If a dilute solution of any auxin is sprayed upon young plants, the possibility of bending of plants is reduced as the stem becomes stronger by the application of auxins.
(10) Differentiation of Xylem and Phloem:
Experiments with intact plants and also of tissue culture have shown that differentiation of xylem and phloem is under the control of auxins.
(11) Sex Expression:
The spray of auxins increases the number of female flowers in cucurbits. In maize, application of NAA (Nepthalene Acetic Acid) during the period of inflorescence differentiation can induce formation of hermaphrodite or female flowers in a male inflorescence. Thus auxins induce femaleness in plants.
We can see now that while the activities of plant hormones parallel those in animals upto a point, the parallel is not complete. The auxins seem to be more general and versatile in their effects. Auxin may influence a plant in many different ways, at least so far as the physical effects are observable. Sometimes it stimulates growth, under other conditions it retards growth.
Sometimes it induces a tumor. Sometimes it kills the entire plant. Such observations lead with increasing clarity to the conclusion that the auxins must influence some basic general cellular process, and that the result of this influence may be expressed in a variety of ways, depending on the nature and age of the tissue, on the availability of other interacting substances, and on the external and internal conditions.
Eating the Hand that Feeds You: Rhizophagy and Plant Nutrition
Those crazy scientists have done it again, throwing generally accepted theories of life science out the window. A group of Australian researchers have shown that plants are able to consume whole bacteria and yeast cells. Prior to this, our understanding of the root/microbe relationship revolved around the idea that microbes provided nutrition to plants. Bacteria can make nitrogen available, as well as solubilize phosphorus, potassium and micronutrients into forms that are plant friendly. Fungi perform a similar role, directly transporting nutrients and water into plants via the mycorrhizal networks. These mechanisms are pretty well understood and accepted as common. What’s not so commonly known is that plants can eat whole microbes. Yes, plant roots are able to devour bacteria and yeasts. The term proposed for this newly discovered mode of nutrition is Rhizophagy (rhye-zo-fay-jee).

The first initiative of DNA barcoding of ornamental plants from Egypt and potential applications in horticulture industry
DNA barcoding relies on short and standardized gene regions to identify species. The agricultural and horticultural applications of barcoding such as for marketplace regulation and copyright protection remain poorly explored. This study examines the effectiveness of the standard plant barcode markers (matK and rbcL) for the identification of plant species in private and public nurseries in northern Egypt. These two markers were sequenced from 225 specimens of 161 species and 62 plant families of horticultural importance. The sequence recovery was similar for rbcL (96.4%) and matK (84%), but the number of specimens assigned correctly to the respective genera and species was lower for rbcL (75% and 29%) than matK (85% and 40%). The combination of rbcL and matK brought the number of correct generic and species assignments to 83.4% and 40%, respectively. Individually, the efficiency of both markers varied among different plant families for example, all palm specimens (Arecaceae) were correctly assigned to species while only one individual of Asteraceae was correctly assigned to species. Further, barcodes reliably assigned ornamental horticultural and medicinal plants correctly to genus while they showed a lower or no success in assigning these plants to species and cultivars. For future, we recommend the combination of a complementary barcode (e.g. ITS or trnH-psbA) with rbcL + matK to increase the performance of taxa identification. By aiding species identification of horticultural crops and ornamental palms, the analysis of the barcode regions will have large impact on horticultural industry.

Botany vs Horticulture: Similarities and Differences
Interested in plants? Want to turn your green thumb into a career? The choices you have for an educational path may be daunting. With infinite terms regarding plants and learning about the care of plants, how do you know or find what you’re looking for? In this month’s Horticultural Science Online blog, we discuss the similarities and differences between botany and horticulture and what you’ll get with a NC State horticulture education.
How is botany different than horticulture?
Botany is defined as “the scientific study of plants, including their physiology, structure, genetics, ecology, distribution, classification, and economic importance” horticulture is defined as “the art and science of garden cultivation and management.”
In both the undergraduate and graduate online programs offered by NC State’s Horticultural Science Department , horticultural science students can apply the science-based knowledge of how plants grow, what they learn in botany, directly to the utilization of plants in various horticultural applications. While students enrolled in the online certificate programs or degree program learn about garden cultivation and management, they also learn about subjects such as plant breeding and the physiology of plants, which gets deeper into the understanding of plants and their culture.
Botany is regarded as a broader, pure science in regards to living plant organisms, from the smallest bacteria to the largest trees. Horticulture, on the other hand, is an applied science under that umbrella and focuses solely on edible and ornamental plant life. While participating in the NC State Horticulture Online Programs, students are able to hone in on specific topics that interest them.
Botany and horticulture in the news: the corpse flower
This year has been a big year for horticulture news and events. Have you heard about the rare corpse flowers blooming all over the country? The titan arum , better known as the corpse flower , takes an incredible 13 years to bloom. Not only is the time it takes to grow astounding, but they are also the largest flowers in the world, and they emit a putrid smell resembling that of rotting animal when they bloom.
This year was a big year for the corpse flower, with many simultaneously blooming in the summer and early fall of 2016 around the United States. Even the NC State horticultural science department had its very own corpse flower blooming in early September. The flowers, which can grow up to 10 feet tall in size, draw large crowds looking to catch a peek—or a sniff—of the incredible rare plant.
A Master’s student in horticultural science and plant breeding, Brandon Huber grew NC State’s corpse flower he spent nine years working on and waiting for the six-foot-tall monstrosity to bloom.
A new attention and vigor exists in the botany, and specifically the horticulture field, due to the brilliant blooming of seven corpse flowers in the United States this year. With exciting events like this, the horticulture field continues to gain interest from more and more potential students.
Check back each month to the Horticultural Science Online blog, as we take a closer look at the field and answer more questions about horticulture.
