Authors: Nesbitt W. B. , Carroll D. E. , Overcash J. P. , Hedgwood C. P. , Stojanovic B. J. 
Published: October 2022

Abstract
‘Doreen’ is a bronze muscadine grape (Vitis rotundifolia Michx.) that can be made into wine equal in quality to ‘Carlos’ and ‘Scup-pernong’. It is self-fruitful, high-yielding, vigorous, resistant to berry shatter, adapted to mechanical harvesting with 50–60% dry fruit stem scars, winter-hardy in the southeast, and is generally disease resistant, including Pierce's disease. It requires 125 days from full bloom to harvest, compared to 100 days for ‘Carlos.’ It ripens in September in south Mississippi and Florida, and in October in North Carolina and north Mississippi.
Advising University Undergraduates in Horticulture1
Authors: Novak Joseph R. 
Published: October 2022

Abstract
Effective academic advising is essential to the development and growth of undergraduate programs in horticulture. In the late 1960s and 1970s, the interest in gardening, concern for the environment, and ecology movement all brought large numbers of students into horticulture, more than many departments could handle effectively. In the 1980s this trend has reversed, as indicated by the decline in number of horticulture students. Attracting students through recruiting programs now has become common practice.
Stimulation of Axillary Shoot Development of Cordyline terminalis ‘Celestine Queen’ by Foliar Sprays of 6-Benzylamino purine1
Authors: Maene L. J. , Debergh P. C. 
Published: October 2022

Abstract
Multiple axillary shoots were obtained from Cordyline terminalis L. ‘Celestine Queen’, treated once weekly for 8 weeks with 6-benzylamino purine (BA) from 100 to 500 mg/liter. At 250-500 mg liter, 78% and 100% of the propagules of the chimeral clone were true-to-type.
Growth and Nitrogen Fixation (Acetylene Reduction) of Elaeagnus umbellata Grown in Ca(OH)2-amended Acid Soil1
Authors: Hensley D. L. , Carpenter P. L. 
Published: October 2022

Abstract
Elaeagnus umbellata (Thunb.) plants were planted in acid soil amended with CaCO3 equivalents of 0.0, 6.6, 13.2, 19.7, 26.4, 52.7, and 102.0 MT/ha of Ca(OH)2 and grown in the greenhouse for 21 months. The pH of the amended soil declined with time. Acetylene reduction rates increased with increasing Ca(OH)2 additions up to 26.4 MT/ha CaCO3 equivalent. The lowest dry matter accumulation in root, stem, leaf and nodule tissue occurred at the lowest pH (3.2) with surviving plants. Dry matter accumulations of leaves, roots and nodules were not statistically different at higher pH values.
Rhododendron Growth at Low Night Temperature1
Authors: Timmerman Jayne C. , Havis John R. 
Published: October 2022

Abstract
Growth of rhododendron rooted cuttings was induced by keeping them at a minimum night temperature of 18.3°C until buds began to swell (10 to 14 days). This treatment produced a subsequent flush of growth that occurred at minimum 4.4° and resulted in spring growth of rooted cuttings of Rhododendron ‘Nova Zembla’ and fall growth of R. ‘PJM hybrids’ with potentially large savings in heat.
Growth of Ilex crenata Thunb. ‘Helleri’ at Different Substrate Nitrogen Levels1,2
Authors: Niemiera A. X. , Wright R. D. 
Published: October 2022

Abstract
Ilex crenata ‘Helleri’ liners were greenhouse grown in sand culture and subjected to N rates which ranged from 14 to 108 ppm in one experiment and from 70 to 250 ppm in a second experiment. Maximum shoot dry weights occurred at 87 ppm N in the first experiment and at 100 ppm N in the second experiment. The number of plants per treatment initiating visible shoot elongation 17 days after the initiation of the fertilizer treatments was influenced by N treatment and 79% of the differences in final dry weights could be attributed to the time of visible shoot elongation initiation. The maintenance of 87–100 ppm N in the substrate nutrient solution, the range at which no further increase in shoot dry weight occurred, would maximize plant growth and most effectively utilize the applied fertilizer.
Screening Highbush Blueberry Cultivars for Resistance to the Aphid Illinoia pepperi1
Authors: Hancock James F. , Schulte Nancy L. , Siefker James H. , Pritts Marvin P. , Roueche Janet M. 
Published: October 2022

Abstract
Sixteen cultivars of blueberry (Vaccinium corymbosum L.) were field screened for resistance to the blueberry aphid Illinoia pepperi (McGillivary), the vector of blueberry shoestring virus. Significant differences were observed with ‘Bluejay’, ‘Northland’, ‘Bluetta’ and ‘Bluehaven’ supporting the lowest numbers, while ‘Spartan’, ‘Darrow’, ‘Lateblue’, ‘Coville’ and ‘Jersey’ carried the highest numbers. There was no significant correlation between aphid number and new shoot number, percentage of shoots with new growth, length of new growth, leaf length or leaf width. Half of the aphids were found in the lower 1/3 of the bushes.
Levels of Inbreeding in Highbush Blueberry Cultivars1
Authors: Hancock James F. , Siefker James H. 
Published: October 2022

Abstract
Inbreeding coefficients were calculated for the 63 cultivars of blueberry (Vaccinium corymbosum L.) released by public agencies in the United States. A steady increase in coefficients was noted from the period of 1910−1920 (F=0.00) to 1960−1970 (F=0.13). ‘Lateblue’ and ‘Flordablue’ had the highest coefficient of 0.25. Most of the genes in the cultivars came from the wild selections ‘Brooks’, ‘Sooy’ and ‘Rubel’.

Authors: Aldrich J. H. , Arnold C. E. 
Published: October 2022

Abstract
Naphthaleneacetic acid (NAA) ethyl ester formulation at 0.25% plus 20% flat white latex paint applied to nonbearing peach [Prunus persica (L.) Batsch] tree trunks reduce sprouting, had no effect on tree growth, and did not induce gummosis.
Effects of Topsoil-subsoil Fertilizer and Lime Amendments on Top and Root Growth of ‘Stuart’ Pecan Seedlings in a Simulated Norfolk Soil Profile1
Authors: White A. W. 
Published: October 2022

Abstract
Fertilizer and lime topsoil treatments increased top and root growth of open-pollinated seedlings of ‘Stuart’ pecan [Carya illinoensis (Wang.) K. Koch] under simulated Norfolk profile conditions in the greenhouse. Positive response was greatest on root growth when lime was added to the subsoil. Rate of tap root growth in the subsoil was increased 64% by increasing subsoil pH from 5.1 to 6.5. Lime additions to the subsoil reduced weights of lateral roots in the topsoil and increased yields in the subsoil. Subsoil lime at 2 and 3 meq Ca/100 g soil (pH 6.0 and 6.5) increased yields of the small feeder roots 3 and 6 fold over the untreated check (subsoil pH 5.1). Acid subsoils can be an important factor limiting growth of pecan roots under soil conditions prevalent in much of the Southeast.
Growth Regulator Effects on Ethylene Production from Calamondin Flowers1
Authors: Southwick Stephen M. , Davies Frederick S. 
Published: October 2022

Abstract
Ethylene production by senescing flowers of calamondin (Citrus madurensis Lour.), at rates as high as 15 nl/g fresh weight-hour did not necessarily induce absicission. Moreover, combinations of gibberellic acid (GA), calcium dihydrophosphate and 6-benzylamino purine (BA), which are known to increase fruit set in citrus, did not significantly decrease ethylene production. Abscission of calamondin fruitlets and increases in fruit set appear to be independent of ethylene production.
Effect of Planting and Harvest Dates on Yield and Quality of Overwintering Spinach1
Authors: Gonzalez Alfredo R. , Horn Roger S. , Marx David B. 
Published: October 2022

Abstract
A comparison was made of ‘Ozarka’ and ‘Green Valley’ spinach (Spinacia oleracea L.) planted in early fall, and harvested in the fall and spring; and planted in late fall and harvested once in the spring. Fall-harvested spinach had no stems, low percentage petioles, and high percentage leaf blades with better green color and lower shear values, pH and titratable acidity as well as higher sensory evaluations than spring-harvested. Spring-harvested spinach from the late fall planting had a higher percentage of undersirable stems and petioles than spring-harvested spinach from the early fall planting.

Authors: Abbott J. A. , Campbell T. A. 
Published: October 2022

Abstract
Appearance, flavor, texture, and overall eating quality of 20 steamed amaranths (Amaranthus spp.) were rated on hedonic scales by consumer sensory panels. Several entries of A. tricolor had nonsignificantly lower scores than spinach (Spinacia oleracea L.). Of the A. tricolor entries, ‘Chin’ was the best overall and ‘Tampala’ (most readily available entry in the U.S.) was intermediate. A. dubius was intermediate and A. cruentus entries were least acceptable.

Published: October 2022

Abstract
‘Ruston Red’ peach [Prunus persica (L.) Batsch] was released by the Louisiana Agricultural Experiment Station (LAES) to provide a high quality, large freestone fruit that ripens about 5 days before ‘Elberta’ or about July 20 in north Louisiana. ‘Ruston Red’ has exhibited high resistance to bacterial leaf spot [Xanthomonas Campestris pv. pruni (Smith 1903) Dye 1978] even when grown in orchards next to trees that were severely infested with the bacterium.
Culture of North American Orchids From Seed1
Authors: Myers Pamela J. , Ascher Peter D. 
Published: October 2022

Abstract
Dehiscence of a mature orchid fruit releases a multitude of seeds — more than a million per capsule in some species. Air currents carry the seeds, but few land on a site permitting germination; even fewer chance upon an environment suitable for development of a mature plant. The seed is microscopic and consists of the bare essentials: a seed coat modified for buoyancy, an embryo of from 8 to 100 cells, and, rarely, a small amount of undeveloped endosperm (2). All orchids require an external source of organic molecules for seed germination or seedling development. After germination, many exist for long periods, the entire life cycle in the case of true saprophytes, deriving carbohydrates and other organic molecules from exogenous sources. Various fungi, in mycorrhizal association with the orchid, provide these complex molecules.
Intergeneric Crosses within Theaceae and the Successful Hybridization of Camellia japonica and C. sasanqua with Franklinia alatamaha1
Authors: Ackerman W. L. , Williams Margot 
Published: October 2022

Abstract
A series of crosses were made between genera within Theaceae including Camellia, Franklinia, Stewartia, and Tutcheria. Two valid intergeneric hybrids were obtained between Camellia and Franklinia alatamaha Marsh. The first, a C. japonica L. (2n=30) × F. alatamaha (2n=36) hybrid with 33 chromosomes, was intermediate in phenotypic characteristics. The second, a C. sasanqua Thunb. (2n=90) × F. alatamaha (2n=36) with 63 chromosomes, was phenotypically very similar to the C. sasanqua parent.
Wide Crosses in Herbaceous Perennials1
Authors: Uhlinger Roger D. 
Published: October 2022

Abstract
A wide cross may be defined as one in which the production of viable hybrid seed is difficult when only traditional methods are using for growing or pollinating the respective parents. It assumes a level of knowledge and skill on the part of the breeder that permits him or her to be successful in making crosses among compatible parents such as those in the “primary gene pool” described by Harlan and deWet (32). Wide crosses would include hybridization of plant materials in that “primary gene pool” with those in the secondary or tertiary gene pools — or beyond. The definition implies that the breeder has a good understanding of the morphology of the reproductive organs of the cultivars/species being used, is aware of existing incompatibility mechanisms, and has access to equipment needed to manipulate plants and the environment in which they are grown. Wide crosses could include those made between: 1) species within a genus; 2) cultivars or species within a genus that differ in ploidy level; 3) cultivars or species from different genera within a family, and, 4) cultivars or species from genera in different families.

Published: October 2022

Abstract
Shoot regeneration has been obtained from leaf and/or cotyledon explants of winged bean [Psophocarpus tetragonolobus (L.) D.C.], Hibiscus acetoseiia Welw. ex. Hiern, muskmelon (Cucumis melo L.), and watermelon [Citrullus lanatus (Thunb.) Mat-sum & Nakai] on 2 media designated HC and BR-1.
Effects of Temperature on the Germination of Selected Wildflower Seeds1
Authors: Kaspar M. J. , McWilliams E. L. 
Published: October 2022

Abstract
Seeds of Coreopsis tinctoria Nutt., Ipomopsis rubra (L.) Wherry, Linum perenne L., and Asclepias tuberosa L. were germinated under constant light at 155 ± 10 μEm−2sec−1 on a thermogradient plate to determine optimum temperatures for germination. Optimum temperatures were 30°C for C. tinctoria, 25° for L. perenne and 30° for A. tuberosa. I. rubra exhibited poor germination at all temperatures in light. C. tinctoria, L. perenne and A. tuberosa germinated within temperature ranges of 15° to 35°, 15° to 25°, and 25° to 35°, respectively. A. tuberosa was the slowest germinating of the 3 species.
Trickle Irrigation Rates and Chrysanthemum Cut Flower Production1
Authors: Harbaugh B. K. , Stanley C. D. , Price J. F. 
Published: October 2022

Abstract
The minimum water requirement to produce the greatest number of marketa- bie cut flowers of Chrysanthemum × morifolium Ramat. ‘Manatee Yellow Iceberg’ was 35 cm with trickle irrigation, a 91% reduction in water uses as compared to overhead irrigation systems. Linear responses for fresh weight, dry weight, leaf area, leaf number, and flower number between 13.6 and 40.7 cm of water supplied during production indicated that an additional 6 cm of water would improve marketable stem's quality.
Snapdragon Production with Supplemental Irradiation from High-pressure Sodium Lamps1
Authors: Stefanis James P. , Langhans Robert W. 
Published: October 2022

Abstract
Supplemental high-pressure sodium (HPS) irradiation of greenhouse-grown snapdragons (Antirrhinum majus L.) at a quantum flux density (QFD) of 105 ± 15 μE m−2s−1 reduced winter flowering time and increased fresh weight and stem length. Flowering time, fresh weight, and stem length were equal when plants were grown at both summer (8 × 10 cm) and winter (10 × 13 cm) spacings under HPS lamps, thereby increasing winter production/m2 by 63%. Reductions in flowering time and increases in fresh weight and stem length for cultivars grown under HPS lamps during the spring were smaller than for plants grown under HPS lamps during the winter. Differences in cultivar response were found in both studies.
Effect of Ammonium and Nitrate Nitrogen on Growth of Poinsettia1
Authors: Gaffney J. M. , Lindstrom R. S. , McDaniel A. R. , Lewis A. J. 
Published: October 2022

Abstract
Rooted cuttings of poinsettia (Euphorbia pulcherrima Willd. ex. Klotzsch cvs. Annette Hegg Dark Red and Eckespoint C-1 Red) were grown under a 16-hour photoperiod in aggregate culture to determine the influence of NH4-N and NO3-N on plant growth. Plant height, number of nodes, and shoot dry weight were reduced with NH4 in comparison to NO3.NH4:NO3 combinations containing more than 50% (6 meq) NO3 produced superior growth. Stunting, leaf chlorosis and abscission, and stubby brown roots were observed on plants receiving any level of NH4 in the nutrient solution and increased in severity as the NH4 concentration increased. Inferior growth observed with the NH4 treatments was not due solely to the higher levels of Cl and SO4 in those solutions.
Deep Supercooling in Roses1 2
Authors: Rajashekar C. , Pellett H. M. , Burke M. J. 
Published: October 2022

Abstract
Deep supercooling of stem tissue water was found in all the native species of rose (Rosa spp.) studied. Freezing of this supercooled water was associated with injury to the stems, indicating that maximum cold hardiness of these species is limited to about −40°C. Therefore, these species have some potential for use in breeding to develop cold-hardy cultivated roses, but their hardiness would be limited to −40°C by the supercooling characteristic.
Effect of Nutrition, Soil Water Content, and Duration of Storage on Quality of Dieffenbachia maculata (Lodd.) G. Don ‘Rudolph Roehrs’1
Authors: Ben-Jaacov J. , Poole R. T. , Conover C. A. 
Published: October 2022

Abstract
Dieffenbachia ‘Rudolph Roehrs’ plants were fertilized at 80, 160, and 240 mg/15-cm pot nitrogen and 80 and 240 mg/15-cm pot potassium every 2 weeks for 5 months, and placed in dark storage for 1, 2, and 3 weeks. Fertilization level did not affect development of leaf senescence or chlorosis during storage, but duration of storage did affect plant quality. Watering plants 24 hours prior to storing, or 10 days before storing, led to a difference in water usage by plants but did not affect storability. The main effect on quality reduction was duration of the dark period.
Influence of Ethephon and Light Intensity on Growth and Acclimatization of Ficus benjamina1
Authors: Johnson C. R. , McConnell D. B. , Joiner J. N. 
Published: October 2022

Abstract
Soil drench of (2-chloroethyl)phosphonic acid (ethephon) at 500 or 1000 mg (active ingredient)/25-cm pot, caused prostrate growth habit and fruit set on Ficus benjamina L. grown in full sun or 47% shade. Leaves of sun plants generally had a mesophyll with multiple palisade layers, while shade plants had only limited regions of multiple cells. Ethephon treatments reduced intercellular spaces in palisade and spongy mesophyll cells, particularly near leaf margins. High shoot/root ratios, reduced leaf area, and heavy leaf drop during an interior phase occurred with ethephon treatment, especially plants grown under full sun.
Chemical Root Pruning of Coniferous Seedlings1
Authors: Burdett A. N. , Martin P. A. F. 
Published: October 2022

Abstract
Conifer seedlings of 10 species from 6 genera were raised in containers coated on the inside with basic cupric carbonate in latex paint. The copper paint prevented lateral roots from growing down or around the container wall. After transplanting, the chemically root-pruned stock was capable, in most cases, of vigorous root growth. The effectiveness of the chemical root pruning treatment varied with species, container size, growing medium, and the concentration of cupric carbonate in the container wall coating.
Effect of Potassium Fertilization and Season on Fresh Market Tomato Quality Characters1
Authors: Picha D. H. , Hall C. B. 
Published: October 2022

Abstract
Fruit quality characteristics of ‘Healani’, ‘Homestead-24% ‘Walter’, and ‘Flora-Dade’ tomatoes (Lycopersicon esculentum Mill.) were determined during the spring and fall season from plants fertilized with 0, 93, 186, 372, and 744 kg K/ha. Reducing sugars, dry weight, and pH were higher in the spring, while titratable acidity was higher in the fall. ‘Healani’ had the highest and ‘Flora-Dade’ had the lowest soluble solids, reducing sugars, dry weight, and pH in each season. Titratable acidity increased with increasing K rate during both seasons, while pH decreased with increasing K rate only during the spring. Each cultivar, except ‘Flora-Dade’, had a higher reducing sugar content with 744 compared to 0 kg K/ha in the spring.
Rooting Studies of Dormant Muscadine Grape Cuttings1
Authors: Goode D. K. , Krewer G. W. , Lane R. P. , Daniell J. W. , Couvillon G. A. 
Published: October 2022

Abstract
Dormant cuttings of muscadine grape, Vitis rotundifolia Michx., rooted best early in the dormant season, although root quality was poor and the percentage rooting was low. Large-diameter cuttings rooted better than small-diameter cuttings. A high percentage of cuttings with aerial roots produced additional root growth. Medium heating was necessary for root formation. No significant rooting response was observed with indolebutyric acid (IBA), (2-chloroethyl) phosphonic acid (ethephon), precallousing, sucrose treatments, or with mallet cuttings.
Fruit Thinning and Russeting Effects of Oxamyl on Apple1
Authors: Meyer Ronald H. 
Published: October 2022

Abstract
Methyl N’N’-dimethyl-N-[(methylcarbamoyl)oxy]-1-thiooxaminidate (oxamyl)-thinned fruit of ‘Golden Delicious’ and ‘Starkrimson Delicious’ apples (Malus domestica Borkh.), as did naphthaleneacetic acid (NAA) and 1-naphthyl N-methyl carbamate (carbaryl). At 12- and 13-mm diameter fruit size, an increase in concentration of oxamyl sprays increased thinning. Oxamyl produced increasingly severe russet on ‘Golden Delicious’ at concentrations above 300 ppm.
Peach Blossom Thinning with CGA 152811
Authors: Krewer Gerard W. , Daniell Jeff W. , Couvillon Gary A. 
Published: October 2022

Abstract
There was an inverse linear relationship between fruit set of ‘Bicentennial’ and ‘Redhaven’ peach trees [Prunus persica (L.) Batsch] and treatments of 0 − 4000 ppm of (2-chloroethyl)methylbis(phenylmethoxy) silane (CGA 15281) in 1980. Increases in fruit weight occurred at the highest rate of CGA 15281 when compared to lower rates with ‘Bicentennial’, but no significant increase was obtained with ‘Redhaven’. Terminal fruit were larger than basal and middle node position fruits in ‘Bicentennial’. In 1981, all applications of CGA 15281 (0 − 3000 ppm) to ‘Candor’ and ‘Jefferson’ thinned blossoms and resulted in an increase in fruit size, when compared to the hand-thinned control. Treatments of 2250, 2500, and 2750 ppm to ‘Candor’ resulted in adequate thinning and increased yields. Applications at 1500 and 1750 ppm resulted in overthinning and reduced yields in ‘Jefferson’.
