Interspecific Grafting to Enhance Flowering in Wild Species of Cucurbita1
Authors: Nienhuis James , Rhodes A. M. 
Published: September 2022

Abstract
Cucurbita pepo L. was found to be the best rootstock to enhance flowering of C. palmata Wats, and C. pedatifolia Bailey scions. Cucurbita ficifolia Bouché was equal to C. pepo as a rootstock for C. okeechobeensis Bailey scions. Cucurbita mixta Pang, rootstock produced flowers with the C. palmata scion. Cucurbita maxima Duch. and C. moschata Duch. ex Poir. rootstocks gave the poorest results.
Virus and Mycoplasmalike Diseases of Blueberry
Authors: Varney Eugene H. 
Published: September 2022

Abstract
Although the fruit of wild Vaccinium species has long been harvested by man, a commercial fruit industry was not established until the early 1920’s with the introduction of highbush blueberry cultivars of V. australe Small and V. corymbosum L. Plants were at first apparently free of serious disease problems, but the new industry was soon threatened by stunt, which was considered a virus disease until the discovery of mycoplasmalike organisms (MLO’s) in plants. Since 1954, several virus diseases have been recognized. Researchers have had the unique opportunity to follow the development of virus and MLO diseases while a native wild plant was modified by plant breeders and brought under cultivation. Information acquired before 1970 and illustrations of symptoms may be found in earlier reviews (10, 11, 12).
The Production of Ground Covers in a Sod-like Manner1
Authors: Sterrett Richard B. , Sydnor T. Davis 
Published: September 2022

Abstract
Euonymus (Euonymus fortunei colorata Rehd.), English ivy (Hedera helix L.), and pachysandra (Pachysandra terminalis Sub. & Zucc.), were evaluated for their capability to produce a mat of ground cover plants in sod-like configuration. Euonymus and English ivy produced a satisfactory product in 12 weeks while pachysandra required 16 weeks. Of 7 media evaluated with English ivy as the test plant, pine bark mulch, peatmoss-perlite, and Metro Mix 300 were judged superior in transportability, overall quality and landscape acceptance to peatmoss-Haydite-perlite, peatmoss-Haydite, peatmoss-sand, and hardwood bark. Euonymus and English ivy sods in pine bark mulch and peatmoss-perlite media were evaluated for landscape establishment. Both species rooted into the soil and established without appreciable loss 6 months after transplanting into the field.

Reducing Russet on ‘Golden Delicious’ Apples with Silicon Dioxide Formulation Foliage Sprays1
Authors: Meador Daniel B. 
Published: September 2022

Abstract
Foliage sprays of silicon dioxide formulation (Apasil) applied at petal fall and at 7- and 14-day intervals following petal fall in 1975 and at petal fall and 7 days later in 1976 significantly reduced russet on fruit of spur-type ‘Golden Delicious’ apple (Malus domestica Borkh.).
Oregon B442-15 and B445-66 Pea Seedborne Mosaic Virus-resistant Breeding Lines1
Authors: Baggett J. R. , Hampton R. O. 
Published: September 2022

Abstract
Pea seedborne mosaic virus (PSbMV) is of concern to breeders and seedsmen, especially in the Pacific Northwest where most of the pea (Pisum sativum L.) seed used in the U.S. is produced (4). Resistance to PSbMV is the best means to remove the threat of seed stock contamination and reduce the need for costly and restrictive assay programs and quarantines.

Abstract
Fresh vegetables from the West Coast of Mexico are a significant factor in filling the bins of markets and supermarkets of the U.S. from October to June. The most important crops involved in this operation are: tomatoes, cucumbers, bell peppers, eggplant, green beans, squash, cantaloupes and watermelons with asparagus, sweet corn, sugar peas, and perhaps other vegetables available in lesser volume.
Tissue Culture Propagation of African Violets1
Authors: Cooke Ron C. 
Published: September 2022

Abstract
Over 70,000 plants of African violet (Saintpaulia ionantha Wendl.) from over 20 cultivars have been produced by tissue culture in this laboratory. All cultures were started from a single mother stock plant of each cultivar. The ease of the method is enhanced by using premixed inorganic salts which eliminate preparation of stock solutions and the development of media for shoot production and root production that differ only in growth regulators. The plant and flowers appear true-to-type and variegations were not lost or distorted. The plants had the typical flat leafed morphology; none had the unusual upright morphology encountered in some cases by Start and Cumming (1). Only 2 plants had obvious differences in phenotype. These were albinos from ‘Mary D’ and could not survive outside artificial media.
Glycoalkaloid Content of Mature Green Fruit of Lycopersicon Species1
Authors: Courtney W. H. , Lambeth V. N. 
Published: September 2022

Abstract
Total glycoalkaloid (TGA) contents were determined in the mature green fruit of 7 lines representing 6 Lycopersicon species. Significant differences were found among all lines except the L. esculentum entries and among clusters within 6 lines. LA 1028 (L. chmielewskii Rick, Kesicki, Fobes & Holle) had the highest mean TGA content of 114 mg/100 g fresh weight; 31-St-34 (L. esculentum Mill.) had the lowest mean TGA content of 7 mg/100 g fresh weight.
Components of Yield and Seed Characteristics in Lentil1
Authors: Wilson V. E. 
Published: September 2022

Abstract
The number of seeds/plant, seeds/pod, flowers/peduncle, and peduncles/plant was greater on lentil plants (Lens culinaris Medic.) grown from small seeds than from medium and large seeds. Correlation studies show that seed yields are inversely related to seed size and plant height.
Response of Southernpea (Vigna unguiculata (L.) Walp.) to Tillage Methods1
Authors: Smittle D. A. , Threadgill E. D. 
Published: September 2022

Abstract
The disk, deep turn and rip-bed methods of land preparation resulted in soil strengths of 1000 kPa or greater at depths of 10, 28 and 18 cm, respectively. The disk and deep turn treatments produced a relatively uniform soil strength across the seed bed at all depths while the rip-bed treatment resulted in a channel of low strength soil under the row with relatively high soil strengths 15 cm to each side. Root growth generally followed the same pattern as soil strength. Shelled pea yield was greatest with the deep turn tillage method and lowest with the disk tillage method. The greater yield was due to a combination of a larger yield per plant and a slightly greater plant stand with the deep turn tillage method. Nutrient use efficiency as determined by total nutrient uptake by plants of the rip-bed and deep turn treatments was 40 and 50% greater than those from the disk treatment.
A Field Study of Color Intensity in Freezing Peas
Authors: Ells James E. , McSay Ann E. 
Published: September 2022

Abstract
Substandard color was encountered in experimental frozen samples of pea (Pisum sativum L.) produced in the San Luis Valley, Colorado in 1973 and 1974. Light green and blond peas were mixed with normal dark peas rendering the samples unacceptable. Peas planted in April, 1975 had satisfactory color regardless or irrigation schedule or tenderometer reading at harvest. May-planted peas generally had inferior color and this was aggravated by frequent irrigations and over maturity.
Two Centrifuge Techniques for Estimating the Carbohydrate and Pigment Status in 6 Genotypes of Corn1
Authors: Arnold Charles Y. 
Published: September 2022

Abstract
Two centrifuge techniques were used to estimate some characteristics of kernels of maize (Zea mays L.) with the genes Su, su, su-IL677a, ae du wx, bt2, and sh2. The first technique produced 4 recognizable layers which could be associated with stage of maturity; sugar, water soluble polysaccharides, and starch; and the production of smooth, wrinkled, and shrunken seed. The 2nd technique resulted in the extraction of pigments. Spectrographic analyses suggested that differences in visual perception at different stages of maturity or among genotypes were associated with differences in concentration rather than types of pigments present.
Microwave Drying: A Rapid Method for Determining Sweet Corn Moisture1
Authors: Becwar M. R. , Mansour N. S. , Varseveld G. W. 
Published: September 2022

Abstract
An accurate, rapid, and simple method of determining % moisture of cultivars of sweet corn (Zea mays L.) using a microwave oven is described. Working with corn in the moisture range of 65.5 to 72.4%, it was possible to obtain readings within ± 1% of those obtained with the standard 24-hour vacuum oven method.

Abstract
Height and number of shoots of both cultivars increased, and color of leaves improved with increased nitrogen. Increased potassium fertilization slightly increased number of shoots but did not affect height or leaf color.
Factors Influencing Seed Germination of Freesia refracta Klatt cv. Royal Mix1
Authors: Gilbertson-Ferriss Terry L. , Wilkins H. F. 
Published: September 2022

Abstract
Seed germination of ‘Royal Mix’ freesia was most rapid and uniform at 15.5° or 18.5°C under clear polyethylene or at 13° or 21.5°C under black polyethylene. Soaking seeds in running water prior to germination or removal of the seed coat did not improve seed germination
Control of Rootsuckers on Apple Trees with Growth Regulators1
Authors: Miller Stephen S. 
Published: September 2022

Abstract
Naphthalenacetic acid ethyl ester (NAA ethyl ester) applied to actively growing rootsuckers on ‘Oregon Spur Delicious’ apple trees (Malus domestica Borkh.) at 0.5 and 1.0% provided effective sucker suppression 70 days after treatment. Combination sprays of NAA and N-butyl-N-ethyl-a,a,a-trifluro-2,6-dinitro-p-toluidine (benefin) or NAA and straight chain fatty alcohols (Off-Shoot-T85) gave good control of rootsuckers. Lower rates of NAA and NAA plus Off-Shoot-T85 were equally effective when a paraffin based petroleum oil spray adjuvant (Agicide Activator) was added. NAA at 1.0% was the only treatment to provide effective rootsucker supression in the season following treatment.
Control of Sprouts on Pyracantha Trunks with Annual Applications of Naphthaleneacetic Acid1
Authors: Boswell S. B. , McCarty C. D. , Nauer E. M. 
Published: September 2022

Abstract
Naphthaleneacetic acid (NAA) formulated as a sodium salt and as the ethyl ester applied in the spring of 1975 and 1976 to unpruned trunks of Pyracantha coccinea (Roem.) cv. Rosedale effectively controlled sprout growth. The 1% concentration of each formulation reduced growth 4 cm more than the 0.5% concentration. The control averaged 49 sprouts and treated plants ranged from 2 to 4 sprouts.
Tree Fruit Nursery Stock Defoliation with Harvest Aide Chemical and Surfactant Mixtures1
Authors: Larsen Fenton E , Lowell Gordon D. 
Published: September 2022

Abstract
Harvade (2, 3 Dihydro-5,6-dimethyl-1,4-dithiin 1,1,4,4 tetroxide) and Dupont-WK (D-WK) surfactant (principle functioning agent the dodecyl ether of polyethylene glycol) in combination stimulated significant leaf abscission on apple, pear, cherry and peach nursery stock. Species and cultivars varied considerably in sensitivity to this chemical mixture, but 1 to 3 applications at weekly intervals of 100 to 200 ppm Harvade and 0.5 to 1.0% D-WK were generally effective without significant damage. Higher rates of chemicals often caused excessive damage, particularly if applied more than twice.
A Simple-leaved Pecan1
Authors: Jones Robert W. 
Published: September 2022

Abstract
A simple-leaved pecan [Carya illinoensis (Wang.) K. Koch] seedling was found in a Riverside seedling nursery by Larry Womack of Womack Nurseries, DeLeon, Texas. This uncommon specimen was preserved by grafting it to a normal pecan seedling rootstock sometime in the early 1960’s. Wood from the variant was grafted on orchard seedlings at the U. S. Pecan Field Station, Brownwood, Texas, in April 1973 and on 1-year-old greenhouse-grown Riverside seedlings in Feb. 1974. This paper reports observations of the growth and gross morphology of this unusual variant.

Grevillea chrysodendron R. Br.: Potential Weed in South Florida1
Authors: Neel P. L. , Will Albert A. 
Published: September 2022

Abstract
Grevillea chrysodendron, an ornamental tree similar to Grevillea robusta Cunn., the silk oak, is native to North Queensland, Australia, and was grown and observed for 6 years at the Agricultural Research Center (ARC), Ft. Lauderdale. During that time 28 trees flowered and shed over 300,000 seeds of which over 300 sprouted in an adjacent fallow field and attained heights of 1 to 2 meters within 2 years. Because of its potentially weedy nature, the planting and the seedlings have been destroyed. The Florida ecosystem is a fragile one which already contains too many escaped, exotic ornamentals.

Published: September 2022

Abstract
We prepare large numbers of samples of short segments of 1 and 2-year-old stems for use in laboratory tests in connection with hardiness studies with woody plants. This is a tedious and time-consuming task when done by hand, so we have developed an apparatus which performs this task efficiently. A description of this apparatus is presented here.
Ancymidol Decreases Chrysanthemum Sensitivity to SO2 Fumigation1
Authors: Johnson C. R. , Joiner J. N. , Gower D. N. 
Published: September 2022

Abstract
‘Shasta’ chrysanthemum (Chrysanthemum morifolium Ramat) showed less SO2-induced leaf necrosis than ‘Hurricane’. The growth retardant a-cyclopropyl-a-(4-methoxy-phenyl)-5-pyrimidine methanol (ancymidol) at 0.16 and 0.48 mg ai/2.5 cm pot reduced SO2 damage on both cultivars. There was positive correlation between stomatal activity (water diffusion resistance) and degree of leaf necrosis from SO2.
Diffusible Inhibitor(s) of Imbibition from Senescent Soybean Pods1
Authors: Krul William R. 
Published: September 2022

Abstract
I noticed that seeds of soybean [glycine max (L.) Merrill cv. Dunn] remained dry and brittle after a prolonged period of rain, even though the senescent pods were thoroughly wetted. This observation led me to hypothesize that pods might contain substances which block imbibition of water by seeds.
Firmness of Harvested Rin and Normal Tomatoes as Affected by Ethylene1
Authors: Gonzalez Alfredo R. , Brecht P. E. 
Published: September 2022

Abstract
Firmness values were determined for isogenic normal and rin tomato fruits (Lycopersicon esculetum Mill.) that were held at 20°C in air or 10 ppm ethylene. Exogenous ethylene induced a slight increase in softening of detached rin fruits but these fruits do not soften as much as normal fruit. A two step sequence for softening is postulated.
Inheritance of Flower Bud Abortion in Cucumber1
Authors: Miller J. C. , Quisenberry J. E. 
Published: September 2022

Abstract
Flower bud abortion, which can influence crop maturity, has been observed in gynoecious and/or predominantly pistillate strains of cucumber (Cucumis sativus L.) Pre-anthesis abortion was completely dominant to non-abortion. The flower bud abortive trait tentatively assigned the symbol Fba was shown to be linked with femaleness with an average map distance of 18 crossover units.
Chilling Injury of ‘Honey Dew’ Muskmelons: Symptoms and Relation to Degree of Ripeness at Harvest1
Authors: Lipton Werner J. 
Published: September 2022

Abstract
Chilling injury (CI) of ‘Honey Dew’ muskmelons (Cucumis melo L.) induced by 2½ weeks of storage at 0 or 2.5°C is characterized by a reddish-tan discoloration of the surface. Affected areas may be diffuse or discrete. CI was less severe at 2.5° than at 0°C and was absent at 5°C. The diffuse type of discoloration disappeared during 3 days at 20°C, particularly if the melons had reached full rather than only minimum horticultural maturity at harvest. Melons of minimum maturity accounted for 44% of the samples, but for 77% of those with CI.

Authors: Blumenfeld A. , Epstein E. , Ben-Tal Y. 
Published: September 2022

Abstract
Ethylene gas promoted abscission of mature-green fruits of olive (olea europaea L.) but did not induce endogenous ethylene production. Ethylene readily penetrated and moved through olive fruits. Mature-black olives did not respond to ethylene.
Translocation of ΝAA in ‘Washington’ Navel Orange1
Authors: Nauer E. M. , Boswell S. B. , Holmes R. C. 
Published: September 2022

Abstract
Naphthaleneacetic acid (NAA) applied to young ‘Washington’ navel orange trees [Citrus sinensis (L.) Osbeck] as a 1% sodium salt or ethyl ester formulation was translocated from the treatment site and inhibited growth of the untreated portion of the tree. The Na salt formulation translocated farther than the ethyl ester formulation.
Feasibility of Satisfying Total Nitrogen Requirement of Non-bearing Prune Trees with Foliar Nitrate1
Authors: Weinbaum S. A. 
Published: September 2022

Abstract
The feasibility of supplying the total Ν requirement of young, non-bearing ‘French’ prune (Prunus domestica L.) trees with foliar-applied NO-3 was assessed based on the amount of Ν absorbed following foliar application of 15N-enriched KNO3 and the seasonal Ν requirement as estimated by the total Ν accumulated over the growing season. Based on these data, 2-year-old prune trees would require more than 140 applications of 1.2% KNO3 per year to maintain normal growth if foliar NO-3 was the only Ν source.
Summer Defoliation Effects on Peach Spring Bud Development1
Authors: Couvillon Gary A. , Lloyd Donald A. 
Published: September 2022

Abstract
Peach (Prunus persica (L.) Batsch) trees defoliated from mid-July to late September of 1972 were observed in March of 1973. There was a relationship between foliation following defoliation and bloom delay the following spring. Trees defoliated on or before August 15, 1972 bloomed later than those not defoliated or trees defoliated after that date. Trees defoliated on August 29 were intermediate in bloom delay and trees defoliated later bloomed with the control. Vegetative shoot length on trees defoliated on July 18 was less than that from trees defoliated on August 1 which was less than trees defoliated on August 15. Other treatments did not differ in vegetative shoot length from the control.

‘Marian’ Geranium1
Authors: Buck Griffith J. 
Published: September 2022

Abstract
The garden, or zonal geranium (Pelargonium. X hortorum Bailey) has been a popular bedding plant in American gardens many years in spite of its sensitivity to high summer night temp and humidities. This sensitivity is not unexpected in a plant whose putative ancestors are native to the subdesert of South Africa, and it remains a dominant trait in both clonal and seed-propagated cultivars. A degree of tolerance to these climatic conditions is evident in the diploid cultivars, ‘Mme. Bucher’ and Mme. Landry’, and is more fully expressed in the tetraploid cultivars ‘Pink Cloud’, ‘Greg-erson’s White’, and ‘Olympic Red’ (2). The objective of our breeding program is to develop a group of cultivars with greater heat tolerance. The first cultivar to successfully combine a compact, floriferous plant habit with satisfactory heat tolerance was ‘Galaxie’. In spite of its obvious faults of botrytis susceptibility and relatively weak flower color, ‘Galaxie’ became an important parent numbering among its progeny ‘Toreador’, ‘Hawkeye’ (1), ‘Skylark’, and the newly named ‘Pearl Bailey’
Crop Intensity Index: A Research Method of Measuring Land Use in Multiple Cropping1
Authors: Menegay M. R. , Hubbell J. N. , William R. D. 
Published: September 2022

Abstract
A time weighted land use index known as the crop intensity index (CII) was developed to assess and compare the actual area-time devoted to crop production with the total area-time available to a farmer or group of farmers during a specified time period, usually one year. The basic CII equation may be adopted to relate the actual area-time devoted to a single crop or group of crops such as vegetables compared to the total area-time available for all crops grown on that farmer’s land, or to assess the relative area-time of a single crop or group of crops compared to the actual area-time relationship of all crops grown on that farmer’s land.
