Chemical Pinching of Azalea with Dikegulac1
Authors: deSilva W. H. , Bocion P. F. , Walther H. R. 
Published: September 2022

Abstract
Foliar application of 0.4 to 0.6% of an aqueous solution of sodium 2,3:4,6-di-O-isopropylidene-2-keto-L-gulonate) (dikegulac, Atrinal) was effective as a pinching agent under commercial growing conditions on all azalea (Rhododenron simsii Planch.) cultivars tested. One to 2 weeks after application the upper leaves turned yellow. Within 4 weeks after treatment the axillary shoots began to elongate and 4-8 weeks later the foliage regained a dark green color. Reproductive shoots treated with dikegulac produced new axillary shoots, but treatment should precede flower initiation for optimal results. At all dosage rates a better pinching effect was obtained with higher spray volumes. A spray volume of 200-300 ml/m2 (2-3 qts/100 ft2), depending on growth stage, is suggested. Dikegulac is a very promising chemical pinching agent for greenhouse azaleas.
Sucrose Pulsing of Gladiolus Stems before Storage to Increase Spike Quality1
Authors: Kofranek Anton M. , Halevy Abraham H. 
Published: September 2022

Abstract
Pulsing gladiolus stems at 21°C with 20% sucrose in combination with AgNO3 before storage of 7 or 10 days resulted in greater floret opening and size than those not pulsed. A silver treatment alone was not effective. The sucrose fulfills the requirements for a carbohydrate source and osmoticum which are necessary for floret growth and development. This treatment with sucrose is recommended prior to shipping or storage of gladiolus for long periods.
One Season's Salt Accumulation in Soil and Trees Adjacent to a Highway1
Authors: Langille Alan R. 
Published: September 2022

Abstract
Soil and hemlock needle samples obtained in Fall, 1972 at various distances from the edge of a newly-opened section of Interstate-95 were analyzed for Na and Cl and compared with samples taken from the same locations the following year. Soil Na was significantly increased to distances of 12 m from the highway's edge after the salting season while soil Cl was increased to a distance of 61 m. Both Na and Cl increased significantly in needle tissue at distances up to 61 m after one salting season.
Host Specificity of the Purslane Sawfly and its Response to Selected Pesticides1
Authors: Gorske S. F. , Hopen H. J. , Randell R. 
Published: September 2022

Abstract
Starvation tests demonstrated that the purslane sawfly (Schizocerella pilicornis Holmgren) feeds only on common purslane (Portulaca oleracea L.) and winter purslane (Montia perfoliata (Donn) Howell). Carbaryl, malathion, and Bacillus thuringiensis (insecticides) and DCPA, trifluralin, and nitrofen (herbicides) kill all sawfly larvae when applied directly to them and their food supply at field recommended rates. Chlorothalonil and maneb (fungicides) had little effect. Herbicides applied to soil with pupating sawflies had no effect on the pupae.
Diffusive Resistance Rates and Stomatal Aperture of Peach Seedlings as Affected by Aluminum Concentration1
Authors: Horton B. D. , Edwards J. H. 
Published: September 2022

Abstract
Peach (Prunus persica (L.) Batsch) seedlings were grown in nutrient solutions containing 0, 222, 666, 1333 or 2000 μM Al. Diffusive resistance (DR) increased as Al concentrations increased and were significantly higher at 2000 μM Al than at lower concentrations. Stomatal apertures were larger on seedlings grown in 666 μM than those in 222 or 1333, those of the check were smaller, and those in 2000 μM Al were the smallest. Root volume decreased as Al concentrations increased. Changes in DR appeared to be more closely related to root volume than to stomatal aperture or density.
Phosphorus and Boron Interaction on Growth of Strawberries1
Authors: Blatt C. R. 
Published: September 2022

Abstract
Three cultivars of strawberry (Frageria × ananassa Duch. cvs. Redcoat, Midway and K68-108) were grown in sand culture and supplied with 4 levels of Boron interacted with 3 levels of Phosphorous. Leaf B values of 2-5 ppm were associated with B deficiency symptoms in ‘Redcoat’ and K68-108. Maximum vegetative growth was obtained when leaf B ranged from 58-116 ppm for ‘Redcoat’ and K68-108 and from 14-33 ppm for ‘Midway’. Leaf P and B were increased when P and B levels in the nutrient treatments increased, however there were no significant leaf P-B interactions exhibited. Leaf Ca increased and leaf K decreased as each cultivar approached maximum growth. Leaf B values for ‘Redcoat’ and K68-108 that were associated with maximum growth were similar to those associated with maximum growth in rutabagas, sugarbeets, barley and several forages. ‘Midway’ was found to be very sensitive to B additions.
Non-equivalance of Left-handed and Right-handed Phyllotaxy in Tomato and Pepper1
Authors: Bible Bernard B. 
Published: September 2022

Abstract
Five cultivars of tomato (Lycopersicon esculentum Mill.) grown in the season of 1973 and 3 cultivars of pepper (Capsicum annuum L.) grown in 1974 were classified into left-handed and right-handed plants respectively according to the clockwise and counterclockwise spiraling arrangement of their alternate leaves around and up the main stem. In 4 of 5 tomato and 2 of 3 pepper cultivars, total yield, in terms of both fruit weight and number of fruit was higher in right-handed than in left-handed plants. The results suggest that the regulation of foliar spirality can perhaps be used to advantage for increasing productivity of certain crop plants with alternate phyllotaxy.
Protein and Total Amino Acid Content Before and After Cooking of Yams (Dioscorea sp.)1
Authors: Splittstoesser Walter E. 
Published: September 2022

Abstract
Tubers from 4 species of yams (Dioscorea alata L., D. esculenta Burkiil, D. rotundata Poir., and D. trifida L.) which ranged from 6.1 to 9.8% total amino acid content on a dry weight basis, were analyzed for total protein and protein-bound amino acids. Percent protein, as protein-bound amino acids, was 68 to 83% of that estimated from Kjeldahl N × 6.25. Total amino acids were 89 to 94% of the value obtained from Kjeldahl determinations. When yams were boiled, 25 to 59% of the non-protein amino acids were removed from the tubers. Kjeldahl N × 5.44 correlated well with the total amino acid content remaining after cooking.
‘Great Northern Star’ Dry Bean Tolerant to Bacterial Diseases1
Authors: Coyne D. P. , Schuster M. L. 
Published: September 2022

Abstract
The bacterial diseases of beans (Phaseolus vulgaris L.), common blight and bacterial wilt, caused by Xanthomonas phaseoli (E. F. Smith) Dawson and Corynebacterium flaccumfaciens (Hedges) Dows., have caused substantial bean yield losses (4). There is no satisfactory chemical control of these bacterial diseases. An objective of our breeding program was to develop an early maturing ‘Great Northern’ (GN) cultivar tolerant to the two bacterial diseases and comparable to the standard GN cultivars. This has been difficult to achieve because of unfavorable linkages, low heritability of the common blight reaction, and the number of genes involved (2). The recently released ‘Great Northern Star’ (‘GN STAR’) combines the desired traits and is described here.
The Mango in Florida
Authors: Malo Simón E. 
Published: September 2022

Abstract
South Florida is the repository of the largest diversity of mango germplasm in the Western Hemisphere and perhaps in the entire world. Hundreds of East Indian, Indochinese and tropical American accessions and their offspring have hybridized here to give entirely new forms which would have been thought impossible to attain in their areas of origin. Cultivars with such desirable commercial attributes as disease resistance, attractive fruit color, flesh firmness, and extended shelf life have been developed. The biennial and unreliable bearing behavior of the Old World mangos has been largely solved in the new cultivars. Indeed, annual mango yields can reach averages of 30 metric tons per hectare in the best orchards of the Homestead area. How has all this come about? What are the circumstances, institutions, and men responsible for this unique achievement?

Authors: Leal F. J. , Soule James 
Published: September 2022

Abstract
Adequate taxonomic or horticultural classifications of pineapple cultivars have not been devised. Hume and Miller’s groups as modified by Py and Tisseau form a good basis but do not emphasize the value of the totally spineless cultivars. Another group, “Maipure,” is proposed at this time.
Revised Guidelines for Reporting Studies in Controlled Environment Chambers1
Authors: _ _ 
Published: September 2022

Abstract
The following revised guidelines3 are proposed for reporting research conducted in plant growth chambers. The precise regulation of environmental parameters attained in growth chambers has enabled investigators to study many plant processes with a precision and reproducibility hitherto unavailable. However, the environmental conditions employed in growth chamber studies often are not reported in detail sufficient to allow comparison of the results with similar experiments, or repetition of the studies in other laboratories.
Influence of Seed Characteristics on Snap Bean Growth and Yield Response1
Authors: Smittle D. A. , Williamson R. E. 
Published: September 2022

Abstract
Seed of snap bean, Phaseolus vulgaris L. cv. Avalanche were separated into 3 length or 3 diameter groups and then each group separated into 3 classes based on aerodynamic properties. The grading procedure resulted in seed grades having large differences in physical characteristics, growth and yield responses. Yield response potential of snap bean was determined primarily by seed weight. A grading method utilizing size grading based on seed diameter followed by aspiration in a vertical air column was the most effective method of eliminating seed with low yield potential.
Hardcore in Sweet Potato Roots as Influenced by Cultivar, Curing, and Ethylene1
Authors: Buescher R. W. 
Published: September 2022

Abstract
Hardcore in sweet potato roots (Ipomoea batatas (L.) Lam) is induced by chilling and subsequent exposure to nonchilling temperatures prior to cooking. The defect is detected only after cooking and could adversely affect consumer acceptance and utilization. Of seven cultivars tested, ‘Red Jewel’ and ‘Jewel’ were the least susceptible to hardcore, while ‘Georgia Jet’ and ‘Jasper’ were the most susceptible. Cured roots were more susceptible than those freshly harvested in all cultivars except ‘Centennial’. Exposure to ethylene during the post-chilling induction period did not reduce the incidence of hardcore but significantly reduced its severity.
Simplified Methods for Inducing Micronutrient Deficiencies1
Authors: Wallihan E. F. , Bradford G. R. 
Published: September 2022

Abstract
The chelating agent ammonium pyrrolidine dithiocarbamate (APDC) was used to remove Fe, Cu, Mn, Mo, and Zn from stock solutions of macronutrient salts. Boron was removed from water with a column of B-specific resin. Characteristic symptoms of Fe, B, Mn, Mo, and Zn deficiencies developed rapidly in tomato plants (Lycopersicon esculentum Mill.) grown in the solutions thus purified.

Chemical Growth Retardation of Dicentra spectabilis (L.) Lem.1
Authors: Lopes L. C. , Weiler T. C. 
Published: September 2022

Abstract
A single spray application of succinic acid-2, 2-dimethylhydrazide (daminozide) at 2,500-15,000 ppm at pinch was effective in retarding growth of bleeding heart, reducing plant height 33 to 75%. A single spray or drench of (2-chlorethyl) trimethylammgrium chloride (chlormequat) had little retarding influence. Spray application of (2-chloroethyl) phosphonic acid (ethephon) had little effect on plant height, but considerably increased the number of nodes and delayed flowering.
Potassium Distribution and Retention in Pine Bark and Sand Media1
Authors: Brown E. F. , Pokorny F. A. 
Published: September 2022

Abstract
Potassium concentration was highest in the upper 5 cm of medium after leaching with 10 cm H2O, lowest in the middle of the soil column (10 and 15 cm depths), and intermediate at the bottom of the column. Increasing concentrations of applied K (336, 671, and 1007 kg/ha) increased the K level in each medium tested, except 100% sand, and at each depth in the soil column. After leaching, media containing high percentages of sand (75 and 100%) had a lower K concentration at all applied K rates than media containing high percentages of bark (0 and 25% sand). Cation exchange capacity was greater in bark than sand and is probably the most important factor influencing the movement of K in pine bark and sand media.
Effect of Training Young Lemon Trees for Limb-shaker Mechanical Harvest on Yield and Tree Trunk Growth1
Authors: Boswell S. B. , Ede L. L. , McCarty C. D. 
Published: September 2022

Abstract
Three year old lemon trees [C. limon (L.) Burm f.] were selectively pruned to form a 3- to 4-scaffold branch structure for limb shaker harvesting. Yield was reduced 16 kg per tree and trunk circumference 10 cm above the bud union was reduced 5.3 cm per tree over a 6-year period. Training was completed with minimal production loss.
The Response of Avocado Fruits to Different Storage Temperatures1
Authors: Zauberman G. , Schiffmann-Nadel Mina , Yanko U. 
Published: September 2022

Abstract
The response of fruits of avocado (Persea americana Mill.) to various temperatures was found to differ in the range 0° to 25°C. This temperature range was divided into 3 groups: 1) between 10° and 25°, the fruit softened at a rate which increases with increasing temperature; 2) between 5° and 8°C, fruit softening was inhibited and the fruit softened only after transfer to a higher temperature; and 3) between 0° and 4° storage life without the occurrence of chilling injury was limited.

Acceleration of the Reproductive Cycle of the Cultivated Blackberry
Authors: Lundergan Catherine A. , Carlisi Jacqueline A. 
Published: September 2022

Abstract
Freshly harvested seeds of the cultivated blackberry (Rubus sp. cvs. Cherokee and Comanche) germinated without stratification when oxygenated in distilled water. Germination was not improved with the addition of 10−5m gibberellic acid (GA) or 10−7m benzylamino purine (BA). Some field-grown plants bloomed the following spring.
Forcing Dormant, Isolated Buds of Blackcurrant
Authors: Wainwright H. , Price D. J. 
Published: September 2022

Abstract
The identification of dormant buds of blackcurrant (Ribes nigrum L. cv. Wellington XXX) as floral or vegetative was attempted by forcing single buds to grow. The influence on forcing of time of year, hormone treatment, and position of buds on the shoots were investigated. Buds grew out more in February than November; gibberellic acid (GA) promoted bud growth in November, while 6-benzylamino purine (BA) at 50 ppm inhibited bud development. Buds that originated from the proximal part of the shoot grew out more than the distal ones.
Bermudagrass Control in Woody Ornamentals with Postemergence-applied Herbicides
Authors: Gilliam Charles H. , Crockett James S. , Pounders Cecil 
Published: September 2022

Abstract
Postemergence applications of 1.1 and 0.6 kg/ha of sethoxydim (2-[l-ethoxyimino) butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-l-one) and fluazifop-butyl (butyl 2-[4-(5-trifluoromethyl-2-pyridyloxy)-phenoxy]propionate), respectively, resulted in 90% control of common bermudagrass (Cynodon dactylon) when applied directly over field-grown ornamentals. Comparable control was achieved by either single application or 2, half-rate, split applications. Of the 12 species tested, only ‘Hexe’ azalea was damaged by applications of fluazifop-butyl to a degree that the plants were unsaleable. All other species exhibited tolerance to both sethoxydim and fluazifop-butyl at the rates required to achieve grass control.
Influence of Controlled-release Fertilizers, Storage Duration, and Light Source on Postharvest Quality of Poinsettia
Authors: Scott Lelia F. , Blessington Thomas M. , Price James A. 
Published: September 2022

Abstract
Plant width and bract color were greater after the production period for ‘Annette Hegg Dark Red’ and ‘Gutbier V-14 Glory’ poinsettia (Euphorbia pulcherrima Willd. ex Klotzsch) when fertilized with Osmocote 14N-6.1P-11.6K than Osmocote 18N-2.6P-10K. Plant height, width, bract color, foliar color, and plant quality increased as fertilizer rates increased from 3 to 9 g/pot. Plants fertilized with 14N-6.1P-11.6K had the least bract loss, greater fresh weight, and the best plant quality after the 30-day postharvest period. Poinsettias fertilized with the lowest rate of 3 g/pot and held for the shortest storage duration had the least leaf, bract, and cyathium loss and highest fresh weight and plant quality. Plants illuminated with the incandescent (INC) light source had the lowest leaf loss and highest fresh weight when compared to cool-white fluorescent (CWF).

Abstract
Apples are an important fruit crop in the high mountains of Mexico. The 4 major apple-producing areas are Cuahutemoc-Guerrero and Nuevo Casas Grandes in the state of Chihuahua, Canatlan in Durango, and Arteaga in Coahuila (Fig. 1). Chihuahua has about 26,000 ha of apple trees, Durango about 13,000 ha, and Coahuila about 8600 ha. At least 60% of the trees are bearing and the 1982 yields (20-kg boxes) were around 12 million, 3.5 million, and 1 million boxes in Chihuahua, Durango, and Coahuila, respectively. ‘Delicious’ and ‘Golden Delicious’ are the main cultivars.

Published: September 2022

Abstract
Measurements of leaf water potential for 5 plant species were made with the J-14 leaf press and a Scholander-type pressure bomb. Although a significant linear relationship was found between the readings from both instruments, the variability in the J-14 readings at a particular pressure bomb value prevents reliable predictions of the pressure bomb valve from the J-14 measurements.

Published: September 2022

Abstract
In a laboratory incubation study with soil inoculum, terrazole [5-ethoxy-3(trichloromethyl)1,2,4 thiadiazole] at 0.02 to 200 ppm in liquid culture suppressed N2 and N2O evolution and increased NO3-N retention. A Cecil clay soil, treated with terrazole at concentrations of 0.5 and 2.0 ppm, retained more NO3-N than the control in a greenhouse study.
In Vitro Somatic Embryogenesis from Callus of Jaboticaba, Myrciaria cauliflora
Authors: Litz Richard E. 
Published: September 2022

Abstract
Callus was induced from adventitious embryos of nucellar origin in cultured ovules from immature fruits of the jaboticaba (Myrciaria cauliflora D.C. Berg.; Myrtaceae) a woody, perennial, tropical fruit tree with naturally occurring nucellar poly embryony. Optimum culture conditions for callus induction consisted of Murashige and Skoog medium that had been modified accordingly: half-strength major salts plus (per liter) 60 g sucrose, 400 mg glutamine, 100 mg ascorbic acid, and 2 mg 2,4-dichlorophenoxyacetic acid (2,4-D). Two months after culturing, a loose callus was induced from the hypocotyls of adventitious embryos from which limited somatic embryogenesis and occasionally organogenesis occurred. Following the subculture of this callus onto solid or liquid medium without 2,4-D, somatic embryogenesis occurred from the callus although this occurred more efficiently and rapidly in liquid medium. Mature embryos germinated normally on hormone-free medium or on medium containing coconut water.
