Seasonal Changes in Zinc and Water-soluble Phenolics in the Outer Trunk Wood of Healthy and Blight-affected Sweet Orange Trees
Authors: Wutscher Heinz K. 
Published: September 2022

Abstract
Healthy ‘Valencia’ and blight-affected ‘Pineapple’ orange [Citrus sinensis (L.) Osbeck] trees, both on rough lemon [C. limon (L.) Burnì, f.] rootstock, had a seasonal pattern of higher Zn in the outer 2.5 cm of the trunk wood in the winter and lower Zn in the summer. The 5-year means for the ‘Valencia’ trees were 5 ppm Zn in February and 3 ppm Zn in July; the blighted ‘Pineapple’ trees contained 21 and 16 ppm Zn (2-year means), respectively. There was no clear seasonal pattern for water-soluble phenolics.
Free Proline in Peel of Grapefruit and Resistance to Chilling Injury during Cold Storage1
Authors: Purvis A. C. 
Published: September 2022

Abstract
Peel samples of ‘Marsh’ grapefruit (Citrus paradisi Macf.) from 2 separate chilling injury (CI) experiments conducted during the 1979–80 season were analyzed for proline. Proline levels were highest in the peel of grapefruit after the seasonal night temperatures reached their minimum and levels declined after night temperatures increased in the spring. The greatest resistance of grapefruit peel to CI during postharvest cold storage coincided with high proline concentrations. Peels of unexposed interior canopy fruit had higher proline contents and were also more resistant to CI than peels of exposed exterior canopy fruit. Proline accumulation may be a consequence of an environmental stress rather than a cause of hardening to the stress or a mechanism of resistance.
Effects of Calcium, EDTA, and Oxalic Acid on Respiration of Apple Slices1
Authors: Himelrick David G. , Ingle Morris 
Published: September 2022

Abstract
Pretreatment or incubation of apple flesh tissue in CaCl2 solutions increased O2 consumption. Tissue incubated in ethylenediaminetetra-acetic acid (EDTA) and oxalic acid showed an initial respiratory burst with a subsequent decrease in respiration after 2 hours. Pretreatment alone did not induce a respiratory burst, but rather caused respiration to lag behind controls. The increased O2 consumption induced by CaCl2 was explained by the presumed restoration of membrane integrity in the senescing tissues which allowed a higher rate of respiration than expected.

Authors: Himelrick David G. , Ingle Morris 
Published: September 2022

Abstract
Six mid-season orchard sprays of ethylenediaminetetra-acetic acid (EDTA), oxalic acid, 2,3,5-triiodobenzoic acid (TIBA), and CaCl, did not consistently influence Ca concentration in leaf, fruit peel, or fruit flesh of 6 cultivars of apple (Malus domestica Borkh.).
Suppression of Ozone-injury on Tomatoes by Ethylene Diurea in Controlled Environments and in the Field1
Authors: Legassicke B. C. , Ormrod D. P. 
Published: September 2022

Abstract
The systematic antiozonant ethylene diruea (EDU: N-(2-(2-oxo-l-imidazoUdinyl)-ethyl)-N1-phenyI urea) was evaluated on ‘New Yorker’ tomato (Lycopersicon esculentum Mill.) in controlled-environment chambers and ‘New Yorker’ and ‘Tiny Tim’ tomatoes in the field. Ozone injury on juvenile plants resulting from 25 pphm (VV−1) for 6 hr day−1 for 2 days was reduced in controlled environments by foliar sprays of 0.5 g liter−1 or soil drenches of 0.15 g per plant. Foliar injury symptoms were not evident on plants in the field, but yields of ‘Tiny Tim’ increased 30% on those plants sprayed weekly with 1.0 g liter−1 or on plants drenched at planting with 0.5 g per plant followed by 2 side dressings of 0.25 g per plant.
Use of Plant Desiccants to Control Cucumber Fruit Rot1
Authors: Halterlein A. J. , Sciumbato G. L. , Barren tine W. L. 
Published: September 2022

Abstract
The plant desiccants, endothall and paraquat, were used in 2 field experiments to study the effect of a reduced plant canopy on the incidence and severity of fruit rot disease of cucumber (Cucumis sativus L.) caused by the fungus Rhizoctonia solani Kuehn. In an experiment planted on May 15, 1979, the most effective desiccant treatment reduced disease incidence by 69% and also reduced disease severity. In a later experiment planted on August 8,1979, desiccants again reduced disease incidence. Paraquat (0.036 kg/ha) applied at first flower reduced disease incidence by 47%. This was consistent with its performance in the earlier experiment. Fungicide treatments with captafol did not reduce disease incidence or severity. The plant desiccants, endothall and paraquat, appear to be potentially useful for controlling cucumber fruit rot disease.

Abstract
Gladioli were merchandised in various ways to measure the market acceptance of the gladiolus as a non-funeral flower. The gladiolus was found to have strong consumer acceptance in both arrangements and loose bunches. Consumer segments especially receptive to the gladiolus were males and persons less than 35 years old.
Influence of Production Light and Ancymidol on Foliage Plants1
Authors: Collins Pamela C. , Blessington Thomas M. 
Published: September 2022

Abstract
Ficus elastica ‘Decora’ Roxb. ex Hornern, Peperomia obtusifolia (L.) A. Deitr, and Hedera helix ‘Hahn’s Self-branching’ L. were produced under 15 and 30 klx light levels and treated with 4 concentrations of ancymidol (alpha-cyclopropyl-alpha-(p-methoxyphenyl)-5-pyrimi-dinemethanol) and several weeks later were placed in an interior holding environment for 6 weeks. Ficus was taller and heavier when produced under 15 klx light; different ancymidol concentrations caused no significant growth effects. Peperomia was taller with increasing light and decreased in growth with ancymidol treatments. After 6 weeks in the interior holding environment, plant grade increased with increasing production light for Peperomia and remained the same for Ficus. Both Ficus and Peperomia maintained similar responses to production treatment after 6 weeks indoors. Hedera was not influenced by production light or ancymidol treatments.
‘Gold Striped Cushaw’ Winter Squash1
Authors: Rhodes A. M. 
Published: September 2022

Abstract
Cultivars of Cucurbita mixta Pang, have been slowly disappearing from listings in seed catalogs in the United States. Several years ago 4 cultivars were listed: ‘Green Striped Cushaw’, ‘White Cushaw,’ ‘Japanese Pie,’ and ‘Tennessee Sweet Potato.’ Today, ‘Green Striped Cushaw’ is occasionally listed. Of the other 3 cultivars, the author has recently seen only fruits of ‘White Cushaw’, which were produced by growers who save their own seed. Although these 4 cultivars of C. mixta are productive, they are very susceptible to powdery mildew, which may account for their decline in popularity.
‘Oregon 17’ Green Bean1
Authors: Baggett J. R. , Frazier W. A. , Varseveld G. W. 
Published: September 2022

Abstract
‘Oregon 17’ is an early maturing bush green bean of ‘Blue Lake’ pod type. Its use may permit an earlier beginning of operations by Oregon processors. ‘Oregon 17’ is about two days earlier than ‘Oregon 1604’, a standard cultivar for commercial canners in western Oregon. ‘Oregon 17’ should yield less than ‘Oregon 1604.’ However, this deficiency may be offset by greater processing efficiency of ‘Oregon 17’ pods, which are smoother and straighter than those of ‘Oregon 1604’.

In Vitro Propagation of Begonia x tuberhybrida from Leaf Sections
Authors: Peck Deborah E. , Cumming Bruce G. 
Published: September 2022

Abstract
An in vitro method of propagating Begonia x tuberhybrida Voss from leaf sections is described. Leaf sections (2 x 2 cm), including a major vein, are submerged partially in a semisolid, bud-inducing medium, containing Murashige and Skoog (MS) salts, vitamins, sucrose, 1.0 mg/liter naphthalene-acetic acid (NAA), and 5.0 mg/liter 6-benzylamino purine (BA). Cultures are maintained in a 16-hr photoperiod at 20°C. After 8 to 10 weeks, the explants, which have begun bud differentiation, are divided and subcultured to a liquid medium containing MS salts, vitamins, sucrose, 1 mg/liter NAA and 1 mg/liter BA, to induce proliferation and development of propagules. The propagules then are placed, in vivo, in an indolebutyric acid (IBA) solution for 10 days to induce rooting. The total time elapsed between taking explants from leaves and the transfer of rooted propagules to pots is just over 5 months.
Yield Potential of Asparagus Irrigated with Geothermal and Ground Water on Imperial East Mesa Desert, California
Authors: Robinson F. E. , Berry W. L. , Scherer D. J. , Thomas T. R. 
Published: September 2022

Abstract
Asparagus (Asparagus officialis L.) cv. UC 157 planted in desert coarse sand in the fall of 1979 and harvested in the springs of 1981, 1982, and 1983 was irrigated with geothermal water, with 2240 ± 1290 ppm total dissolved solids and ground water 1430 ± 460 ppm total dissolved solids. Yields of 3.1 MT/ha of large spears were obtained with ground water and 0.03 MT/ha with the geothermal-irrigated asparagus. Na and Li were significantly increased in the spears that received geothermal irrigation, and B and Fe were significantly increased in those irrigated with ground water. Toxic accumulation of elements in the spears did not occur when geothermal water was used for irrigation, but yields were reduced.
Anticrustant Effects on Chile Pepper Stand and Yield
Authors: McGrady John J. , Cotter D. J. 
Published: September 2022

Abstract
Experiments were conducted in 1979 and 1980 to evaluate anticrustant (H3PO4 and Nalco 2190) effects on stand establishment, growth, and yield of chile pepper (Capsicum annuum L.). While plant stands and fruit yield were not increased by applying H3PO4 over the seeded row in 1979, hypocotyl stress of germinants was reduced. Stands and P content in 1980 were not increased by H3PO4 or Nalco 2190 treatments 1 month after emergence, but plant height was increased significantly by both anticrustants. Yields of fresh green chile peppers were not enhanced by treatments. While germinant stress could be reduced by using anticrustants, it was concluded that a factor other than crusting was limiting chile seedling growth in southern New Mexico.
Seasonal Concentration of the Pierce’s Disease Bacterium in ‘Carlos’ and ‘Welder’ Muscadine Grapes Compared with ‘Schuyler’ Bunch Grape
Authors: Hopkins D. L. , Thompson C. M. 
Published: September 2022

Abstract
The accumulation of Pierce’s disease bacterial occlusions in xylem vessels of leaves of susceptible ‘Schuyler’ bunch grapes occurred 2 months earlier than the accumulation in leaf vessels of the more tolerant ‘Carlos’ and ‘Welder’ muscadines. The first appearance of leaf marginal necrosis symptoms occurred when the accumulation of bacterial occlusions was approaching the maximum—the last week of June in the bunch grape, the last week of Aug. in the 2 muscadines. The site of bacterial accumulation was primarily in the leaves of ‘Carlos’, but in both leaves and stems of ‘Schuyler’ and ‘Welder’. Stem dieback symptoms are more common in the latter 2 cultivars.
Seed Germination of Tall Fescue and Kentucky Bluegrass as Affected by Adhesives
Authors: Hathcock A. L. , Dernoeden P. H. , Murray J. J. , Wehner D. J. 
Published: September 2022

Abstract
The adhesives gum arabic, Methocel A-15, Pelgel, Solka Floe, and 2 experimental materials were evaluated for their effect on germination and early seedling growth of ‘Kentucky 31’ tall fescue (Festuca arundinacea Schreb.), and ‘Adelphi’ Kentucky bluegrass (Poa pratensis L.) and for their ability to retain a limestone seed coating. The adhesives did not adversely affect seed germination, turf quality, and early growth of seedlings of either species. Seedling growth of ‘Adelphi’, however, was enhanced by Methocel A-15 when compared to the control. Adhesive effectiveness for the retention of a limestone seed coating was in the order: Methocel A-15 > Pelgel > Solka Floe > AP-1 = AP-2.
Tipburn of Chlorophytum comosum ‘Vittatum’
Authors: Ben-Jaacov J. , Poole R. T. , Conover C. A. 
Published: September 2022

Abstract
Applications of fluoride and boron produced tipburn on Chlorophytum comosum Jacques ‘Vittatum’. Experiments were established to compare damage caused by F and B to Chlorophytum and to determine the influence of environmental factors and soil amendments on this damage. Damage incited by B was more severe than that incited by F and was unaffected by temperature. At 24°C and 15 µmol s-1m-2, increasing F did not produce tipburn, but at 31° maximum and 150 µmol s-1m-2, chlorophytum tips were damaged by increasing F. CaCO3 slightly decreased F damage but did not affect B damage.

Seasonal Variations in the Effects of CO2 Mist and Supplementary Lighting from High Pressure Sodium Lamps on Rooting of English Holly Cuttings
Authors: French C. J. , Lin W. C. 
Published: September 2022

Abstract
Injecting CO2 gas into mist water (CO2 mist) promoted rooting of Ilex aquifolium L. ‘Silver Variegated Standard’ stem cuttings in spring propagation while inhibiting rooting in the fall. Supplementary lighting from high pressure sodium lamps (HPS) for 16 hr daily had similar effects as CO2 mist in the spring and inhibited root growth in fall propagation. There was a positive interaction between CO2 mist and HPS in spring propagation, suggesting that the promotive effects of these variables were due to enhanced photosynthesis.
The Effect of Orchard Floor Management and Nitrogen Fertilization on Nutrient Uptake and Fruit Quality of ‘Golden Delicious’ Apple Trees
Authors: Neilsen G. H. , Meheriuk M. , Hogue E. J. 
Published: September 2022

Abstract
Mature ‘Golden Delicious’ apple trees (Malus domestica Borkh.) were subjected for 3 years to factorial combinations of 3 rates of N fertilization applied in April and 3 degrees of orchard floor management. Tree N nutrition was affected more by vegetation management than by rate of N fertilizer applied. Significant reduction in leaf N and trunk diameter, and superior fruit skin color and firmness at commercial harvest occurred consistently when the orchard floor was sod. Increased leaf N and reduced fruit skin color and firmness at harvest were measured at the highest N (180 kg N ha-1) in only 1 year while tree growth was not increased by this rate of N. Increased fruit Ca associated with smaller fruit and increased leaf Mg and leaf K were measured under sod in 2 of 3 years. Leaf Mn was affected only by rate of N fertilization and was consistently high at 180 kg N ha-1.
A Nondestructive Method for Measuring Shoot and Root Fresh Weights
Authors: Young Eric , Werner Dennis J. 
Published: September 2022

Abstract
A technique is described for obtaining nondestructive estimates of shoot and root fresh weight using Archimedes’ principle that the buoyancy of an object is equal to its volume times the density of the submersion fluid. Apple and peach seedlings grown in solution and sand cultures for 14 weeks were measured periodically using this technique. Destructive measurements also were taken for comparison. Estimated and actual shoot weights were not significantly different for seedlings grown in a solution culture; however, they were significantly different in sand culture. Coefficient of determination (r2) values of estimated shoot weight regressed on actual shoot weight were over 0.99 for all groups of seedlings.
A Comparison of Pollen Size in Sweet and Sour Cherry
Authors: Iezzoni A. F. , Hancock A. M. 
Published: September 2022

Abstract
Pollen samples from 4 sour cherry (Prunus cerasus L.) and 13 sweet cherry (P. avium L.) cultivars were examined by scanning electron microscopy (SEM). Pollen size did not differ significantly between species or ploidy level. Variability in size both within and among cultivars was greater in sour cherry than in sweet cherry. Giant pollen grains occurred in a low frequency in both sweet and sour cherry, equatorial diameter being responsible for the increased size.
Effect of Different Perforations in Polyethylene Films on Quality of Head Lettuce after Transcontinental Shipment
Authors: Yi Wang Chien , Hinsch R. Tom , Kindya William G. 
Published: September 2022

Abstract
The effects of different perforations in polyethylene (PE) films used as individual wraps on the quality of iceberg lettuce (Lactuca sativa L.) were evaluated after cross-country shipment from California to Maryland, and after shipment plus storage and holding periods. Butt discoloration was more severe in the naked lettuce than in the PE packaged heads immediately after the transcontinental shipment, but this difference was not as evident after 3 days of holding at 15°C or after 2 weeks of storage at 3°. Number of discolored ribs was consistently lower throughout transportation, storage, and holding periods with lettuce packaged with 0.032 mm PE with 285 perforations/cm2 or packaged with 0.025 mm PE with 112 perforations/cm2 than with lettuce of other treatments. Lettuce packaged in 0.013 mm PE with 10 mm slits had the least weight loss among all the treatments after shipping plus 2 weeks of storage at 3°. However, the decay was more severe in this treatment than in those packaged with perforated PE films. Russet spotting occurred in all the treatments after storage and holding following shipment, but the severity was not associated with packaging treatments. More heads remained salable after 2 weeks at 3° plus 3 days at 15° following shipment in the treatments packaged with perforated PE films than in other treatments, primarily because of less decay and fewer discolored ribs.
Factors Influencing Cucumber Mosaic Virus Symptom Development in Pepper
Authors: Pasko P. J. , Nicklow C. W. , Moorman G. W. 
Published: September 2022

Abstract
Beginning one week after the onset of flower bud formation, greenhousegrown pepper (Capsicum annuum L.) plants were innoculated each week with cucumber mosaic virus (CMV) for a period of 12 weeks. In the initial experiment, begun 30 Dec. 1980, almost all fruit with CMV symptoms were harvesed from plants which were inoculated 5-8 weeks after flower initiation. When the experiment was repeated, beginning 31 May 1981, symptoms were found only on fruit harvested from plants which were inoculated 3-6 weeks after flower initiation. Increasing the temperature from 21° to 32°C decreased the number of days between inoculation and the initial appearance of virus crystals. Increasing the day length from 5 to 20 hr also decreased the incubation period. The results suggest the best stage of plant development for inoculation with CMV if fruit symptoms are desired for a disease screening program, and the best temperature (32°), and day length (20 hr) for a reduced incubation period.
Cultivar and Growing Season Effects on Cabbage Head Development and Weight Loss During Storage
Authors: Sundstrom F. J. , Story R. N. 
Published: September 2022

Abstract
Ten cultivars of cabbage (Brassica oleracea v. capitata) were grown in the fall and spring seasons. Cultivar differences in medial and longitudinal head diameter, core length and width, head firmness, and yield were significant within each season. Spring temperatures and daylengths seemed to be more favorable for greater crop production than fall conditions. Growing season significantly influenced head shape and core length. Head shape was conical in the fall, and rounder in the spring. Core elongation was significantly greater in the fall crop. Regression equations show that the percentage of weight loss during storage was lowest at 1°C, and increased with increasing storage temperature.

Unsteady flow analysis using hydrological and hydraulic models for real-time flood forecasting in the Vamsadhara river basin
Authors: Mahapatra Arunima , Mahammood Vazeer , Venkatesh K. 
Published: September 2022

Abstract
The river Vamsadhara runs through the states of Andhra Pradesh (AP) and Odisha along a stretch of coastline that is prone to cyclonic storms. Riverine flow, along with cyclonic gales, is a crucial issue for most of India's coastal districts. As a result, a developed flood forecasting model is required to mitigate the danger of flooding to a certain level. For evaluating maximum water depth and inundation of flood plains induced by storms under existing and future land use circumstances, hydrological and hydraulic models are more prominently studied. The current work employs hydrological and hydrodynamic models to simulate a real flood inundation model for unsteady flow conditions. The technique involves the processing of the digital elevation models (DEM) to generate flood hydrographs that serve as boundary conditions for the reaches. In the present analysis, Manning's roughness coefficient is used as a sensitive parameter. Calibration and validation of extreme flood events that occurred in 2006, 2010, and 2013 using observed water levels yielded good results, with model performances of 0.79, 0.68, and 0.84, respectively. The findings of the generated depth, velocity, and flood extent maps are presented. These maps can be used to plan for flood disasters and long-term watershed management.
