THE INFLUENCE OF SHELTERBELT ON MUSKMELON PRODUCTION.
Authors: Daningsih Entin , Hodges Laurie , Brandle James R. , Stroup Walter W. 
Published: February 2019

Windbreaks can increase crop growth and improve crop quality. The effects of shelter on vegetable production varies with crop, location, and farming practices. While the advantages of minimizing wind stress on vegetable production is well-known, little research documents the specific response of vegetables to microclimate modification through the use of shelterbelts.
During the summer, 1991, a preliminary experiment was conducted on the effects of tree windbreaks (shelterbelts) on muskmelon plant growth, yield, and fruit quality. A split-plot design was used with shelter and exposed areas as main treatments with 3 replications. Subtreatments were 7 combinations of anti-transpirant and time of application. Leaf growth was measured 4 and 6 weeks after planting. Muskmelon fruit were harvested over a 6 week period at 2 day intervals. Muskmelon yield, fruit and cavity diameter, fruit color, and total sugar content were obtained.
The use of anti-transpirant did not significantly affect total yield, fruit or cavity diameter, total sugar content, or early leaf growth. The effect of shelter varied with the measured variable.
EFFECT OF TEMPERATURE ON KIWIFRUIT MATURATION
Authors: Seager Nicky G. , Hewett Errol , Warrington Ian J. 
Published: February 2019

In New Zealand, harvest maturity for kiwifruit is determined by the soluble solids concentration (SSC) of juice (minimum 6.2%). Commercial maturity differs in various regions of the country within each season and between years and may be due to differences in temperatures during growth.
Mature `Hayward' kiwifruit vines were grown in controlled environment temperature treatments of 14/8, 18/8, 22/8, 26/8, 14/12 and 22/12C to determine whether the increase in SSC at low night temperatures recorded in a related study was a result of the mean temperature, the min. daily temperature, or the magnitude of the max./min. temperature difference. Measurement was made of fruit size, firmness, starch and total sugar concentrations in the fruit at 10 day intervals.
SSC increased fastest with the coolest mean temperature irrespective of the min. temperature or max./min. difference. In the coolest treatment the concentration of starch decreased rapidly with a rise in total sugar, in the warmest treatment the change in the carbohydrate components was slower. Data will be used to predict harvest date at commercial orchard sites based on field temperature measurements.
USING INTERACTIVE C.A.D., VIDEO DISC, AND COMPUTER-ASSISTED PLANT SELECTOR TO TEACH LANDSCAPE DESIGN.
Authors: Vanderploeg John F. 
Published: February 2019

Computer assisted plant selection coupled with video disc technology allows students with limited experience in plant identification and selection to successfully complete landscape design plans.
The plant selector and video disc components have been integrated into a C.A.D. program producing a complete work station. Students preparing computer generated designs can refer to both the selector and video disc without leaving the C.A.D. environment. This integration has proven to be an effective teaching tool in landscape design instruction.

The State Of Illinois passed legislation banning landscape wastes deposition in land fills. Approximately 18% of all solid wastes going into Illinois landfills were landscape wastes including grass clippings, branch prunings, leaves and wood. A cooperative program between the Horticulture Department, the Cooperative Extension Service and the Illinois Department of Energy and Natural Resources was initiated to train county extension advisers, municipalities, and the consuming public on methods for landscape waste reduction and recycling.
Workshops, video tapes, Master Composters, mobile displays, fact sheets and a model municipal composting facility were developed. Publications and other educational materials will be displayed.
CALORIMETRIC MEASUREMENTS OF STRATIFYING PEACH SEEDS AND SEEDLING GROWTH
Authors: Moreno Y. M. , Gardea A. A. , Azarenko A. N. 
Published: February 2019

`Lovell' peach seeds were stratified for 0 to 13 weeks at 4C under moist conditions. Heat of metabolism and CO2 evolution, measured by Differential Scanning Calorimetry, increased with stratification time. The calorespirometric ratio increased between 0 and 6 weeks and then remained constant until 13 weeks. Germination percentages paralleled this ratio and reached 80% only after 6 weeks of stratification.
After radicle emergence, seedlings from different stratification treatments were grown for 3 weeks. Increasing stratification time resulted in taller seedling growth. Calorimetrically measured CO2, evolution and the calorespirometric ratio of the apex (one cm) of the seedling increased with longer stratification time. Contrary to the observations of the seeds, metabolic heat rates decreased as stratification time increased. Yet, seedling sustained higher growth rates. These data suggest that the stratification treatment resulted in an improvement in metabolic efficiency.
INFLUENCE OF INCREASED ROOT MEDIA PHOSPHORUS LEVELS IN POINSETTIA PRODUCTION
Authors: Whipker Brian , Hammer P. Allen 
Published: February 2019

Acidification of the irrigation water with phosphoric acid is a common practice to avoid nutrient deficiencies/toxicities from alkaline root media. It has been suggested high phosphorus levels could cause phosphorus toxicity.
Euphorbia pulcherrima Willd. cultivars Supjibi and Celebrate 2 cuttings were potted on June 6, 1991 in a root medium of peat, perlite and soil (40:40:20 by volume) amended with N, K, Ca and micro-nutrients, plus six phosphorus (0-40-0) rates of .89, 1.78, 3.55, 7.11, 10.67, and 14.22 kg/meter3. Foliar samples were analyzed for NH4, P, and K every two weeks after the start of short days. Root media samples were also collected and analyzed pH, SS and NO3, P, K and NH4. Bract diameter, bract edge burn, days to anthesis, and plant height were recorded at anthesis.
Media P levels increased as the phosphorus rate increased, but a significant treatment*harvest interaction for media P was observed. There was decreased bract size and increased incidences of bract edge burn as phosphorus rate increased. Root media P levels did not affect the levels of other nutrient elements in the foliar samples. No visual symptoms of phosphorus toxicity was observed except for bract edge burn at anthesis.
CONTAINER ELECTROCONDUCTIVITY STRATIFICATION IN METROMIX 350 AFTER HARVEST OF TOP- AND SUBIRRIGATED GERANIUMS
Authors: Khoury N.S. , Holcomb E.J. , White J.W. , Rand M. 
Published: February 2019

Excessive electroconductivity measurements have been observed in the surface layer of subirrigated substrates. A hydrophilic gel and rockwool were used as pot mulches in order to reduce the surface layer salt buildup by absorbing the salts and/or reducing evaporation.
Six treatments of `Crimson Fire' and `Victoria' CVI geraniums were grown in 11 cm. pots. Treatments were: Trt 1 - top irrigation, N source 20-10-20; trt 2 - subirrigation, N source 20-10-20; trt 3 - subirrigation, N source in equal portions of 20-10-20 and CRF, gel mulch; trt 4 - subirrigation, N source CRF, gel mulch; trt 5 - subirrigation, N source in equal portions of 20-10-20 and CRF, wool mulch; trt 6 - subirrigation, all N source CRF, wool mulch.
Pots were divided into 3 equal volume portions. Electroconductivity, as a measure of soluble salt (SS) level, was taken. All treatments had increasing SS levels with increasing pot height. Trt 2 had surface layer salt levels significantly higher than trt 1. `Victoria' trts 3,4,5 and 6 surface layers had significantly lower SS levels than trt 1 surface layers. `Crimson Fire' trt 4's surface layer had significantly lower SS levels than the surface layer of trt 1. Trts 4 and 6 bottom layers of both cultivars had significantly lower SS levels than all other treatments.
ACTIVE SUBSATNCES IN CHINESE CHIVE AND RAKKYO PLANTS FOR BREAKING BUD DORMANCY IN GRAPEVINES
Authors: Kubota Naohiro , Kawazu Kazuyoshi 
Published: February 2019

We previously found that volatile substances in Chinese chive (Allium tuberosum) and rakkyo (A. chinense) as well as garlic (A. sativum) stimulated budbreak in vines. But the active substances stimulating budbreak in Chinese chive and rakkyo have not yet been identified.
The volatile sulfur—containing substances in fresh Chinese chive and rakkyo were identified by GC—MASS. The main volatile substances in Chinese chive and rakkyo were allyl and methyl mercaptans, and dimethyl disulfide, respectively.
Cuttings witn a single bud obtained from `Kyoho' vines in dormancy were exposed to vapors of different concentrations of the three compounds for 12 or 24 hr in a desiccator, and they were kept at 25C, mounted on styrofoam plate floated in water. Diallyl disulfide, a main component in garlic, was also tested for comparison. Irrespective of concentrations and exposure periods of sulfide compounds, sprouting was greatly accelerated with diallyl disulfide. In mercaptan homologues, allyl mercaptan accelerated sprouting more effectively than in methyl mercaptan. A solution of 75% dimethyl disulfide accelerated sprouting on exposure for 12 hr, while inhibited budbreak for 24 hr.

Published: February 2019

Since 1987 some chemicals have been examined for thinning of apple, while concidering the safety for humans, animals and bees. Ethyl 5-chloro-3 (1H) - indazorylacetate (Ethychlozate) had the same effect as Carbaryl on `Fuji' cultivor Suitable results were obtained by 40ppm solution spray at 2 to 3 weeks after full bloom. An addition of 300ppm Ethephon increased thinning effects on `Fuji'. But over thinning occured on `Tsugaru'. `Jonagold' and `Jonathan' by same concentration of Ethychlozate or Ethychlozate plus Ethephon.
Thinning effects were more severe on the lateral fruits than on the center fruits. The results were advantageous for apple growing in Japan as center fruits are very important. Epinasty, russet and other injuries caused by Ethychlozate sprayed were not recognized.

Published: February 2019

Lack of winter chilling periodically becomes a serious problem for commercial peach producers in the Southeast, especially along and near the Gulf Coast areas. Studies were conducted over 3 years (1989-1991) to evaluate the effects of hydrogen cyanamide (Dormex - SKW) on replacing lack of winter chilling in 7 varieties of peaches.
Initial findings using whole tree sprays to point of runoff indicated a problem with efficacy and phytotoxicity. A combination of hydrogen cyanamide rates (0, .5, 1, 2 and 4% V/V) and timings (0, 25, 50 and 75% of chilling level) were evaluated in 1991. Rates above 2% were phytotoxic. Rates of 0.5 to 1.0% were safe and effective when applied at 75% chilling.

Authors: Arif Mahmoud B. , Khatamian Houchang 
Published: February 2019

Surface sterilized stem nodal sections of western soapberry (Sapindus drummondii Hook. & Arn.) were cultured on Murashige and Skoog (MS) medium. The basal media consisted of one half and full strength MS medium each supplemented with the following (mg-1): Nicotinic acid 0.5, pyridoxine Hcl 0.5, Glycine 2.0, myo-inositol 100, sucrose 30,000 and agar 8000. Each medium also was supplemented with either 0, 0.01, 0.1, 1.0 and 10 mg/l Thidiazuron (TZD) or 0, 0.5, 2.0 and 5 mg/l 6-Benzyladenine (BA). The pH of all media was adjusted to 5.8 ± 0.1. The culture media were autoclaved at 120°C at 1.5 Kgcm-1 pressure for 15 min.
The highest percentage of nodal sections resulting in shoot regeneration occurred on 1/2 MS with TZD at 0.01 mg/l and MS medium containing 0.5 mg/l of BA Increasing the TZD concentration above 0.1 mg/l resulted in callus formation on cut surfaces.
BREEDING STRATEGIES AND METHODS FOR FOLIAGE AND FLOWERING ORNAMENTALS
Authors: Donselman Henry M. 
Published: February 2019

Tissue culture labs based in countries with high labor costs are becoming more dependent on proprietary plants. This has increased the necessity of high profile plant breeding programs. Foliage and flowering plant breeding programs have evolved rapidly to take advantage of the benefits associated with tissue culture labs.
Breeding strategies and methods will be discussed on existing flowering and foliage programs for Anthuriums, Euphorbia, Aloe, Spathiphyllum, Homalomena, and Dieffenbachia. Embryo rescue in the lab has increased the survival of wide crosses from different species within a genera. Rapid multiplication of selected clones has increased the efficiency of screening for disease and insect resistance in the selection of new cultivars. Marketing, along with improved horticultural characteristics, determine the success of new releases.
EFFECT OF DAMONOZIDE, ANCYMIDOL AND PACLBUTRAZOL ON HEIGHT CONTROL OF POTTED MUSSAENDA
Authors: Cramer Christopher S. , Bridgen Mark P. 
Published: February 2019

Mussaenda, a tropical, hybrid ornamental plant from India and the Philippines, is being evaluated as a potential greenhouse ported crop in the united States. Showy sepals of white, picotee (White with rosy edges), light pink, dark pink, or red complemented by fragrant, yellow flowers and dark green, pubescent foliage make Mussaenda a very attractive potted plant. However, sometimes the height of Mussaenda is unsuitable for pot plant culture. With the use of chemical growth regulators. plant height is reduced thus making Mussaenda a more feasible potted crop. In the summer of 1992, a growth regulator study was conducted to evaluate three growth regulators and concentrations capable of reducing plant height in Mussaenda. Daminozide (B-Nine SP), ancymidol (A-Rest), or paclobutrazol (Bonzi) was applied at two concentrations each. Daminozide was tested as a spray at 2500 ppm and 5000 ppm. Ancymidol was applied as a spray at 33 ppm and 66 ppm or as a drench at 0.25 mg/pot and 0.50 mg/pot. Paclobutrazol was tested as a spray at 25 ppm and 50 ppm or as a drench at 0.125 mg/pot and 0.25 mg/pot. Growth regulators were applied as a single application or a double application with two weeks separating applications. Daminozide at 2500 ppm and 5000 ppm was most effective in controlling plant height. Ancymidol as a drench at 0.25 mg/pot and 0.50 mg/pot was also effective in plant height control. Two applications of these growth regulators were more effective in controlling plant height than a single application.
FUNGAL PATHOGENS FOR BIOCONTROL OF INSECTS IN GREENHOUSES.
Authors: Brownbridge Michael , Parker Bruce L. , Skinner Margaret 
Published: February 2019

Western flower thrips (WFT), green peach aphid (GPA) and sweet potato whitefly (SPWF) are major pests of the greenhouse industry. Chemical control of these pests is not desirable. Alternative approaches to pest management need to be developed. Entomopathogenic fungi hold great promise as sustainable biological control options. A broad range of indigenous fungal isolates have been screened for activity vs. WFT and GPA. Strains of Metarhizium anisopliae, Beauveria bassiana and Verticillium lecanii have been shown to be particularly effective. Plant and soil trials vs. WFT are now underway to permit selection of the best strains for further development. To date, assays vs. SPWF indicate that strains of Paecilomyces farinosus and B. bassiana are the most pathogenic.

Published: February 2019

The effects of sequential foliage topping on two sweetpotato [Ipomoea batatas (L) Lam cvs Georgia Jet, TU-82-18921 cultivars were investigated in a field trial. Three initial foliage cuttings (15 cm cutting from the growing tip) were initialed at 45.60 and 75 days after planting (DAP). Each initial cutting date was followed by zero, one or two cuttings at biweekly intervals. Total storage root yields were not affected by cutting treatments regardless of the cultivar investigated. Both cultivars differed in their response in dry matter accumulation, while Georgia Jet was not affected by cutting treatments, TU-82-1892 accumulated less dry matter when foliage tips were removed twice during the growth cycle (75.90 DAP) compared to all other cutting treatments. The amount of foliage tips removed from each cultivar differed significantly over all treatment levels with Georgia Jet producing more foliage tips than TU-82-1892. However. production of foliage tips for both cultivars was greatest when foliage cutting was delayed until 75 DAP.

001 COLLABORATIVE LEARNING AND PARTICIPATORY ON-FARM RESEARCH: COVER CROPS AND VEGETABLE PRODUCTION SYSTEMS
Authors: Luna John M. , Green-McGrath Daniel , William Ray , Seiter Stefan , Tenas Tom 
Published: February 2019

A participatory, on-farm research project was initiated in 1992 in an effort to enhance mutual learning, knowledge, and experience of integrating cover crops into western Oregon vegetable production systems. A major goal of the project was to include growers, agribusiness representatives, governmental agency, Extension and university researchers in a collaborative learning process, emphasizing grower participation in the design and implementation of on-farm research and demonstration projects. To facilitate this participation from the planning stage forward, four “focus sessions” were hosted by lead farmers in different areas of the Willamette Valley to define growers' needs and interests relating to on-farm research and demonstration trials.
Based on individual growers' specific experimental objectives, cover crop evaluation trials were established on ten farms. Typically on each farm, 5 to 10 cover crop species or mixtures (grain and legume) were planted in large plot strips. Twenty five different cover crop species, varieties, and mixtures were planted. Seasonal cover crop biomass and nitrogen accumulation rates were determined, with cover crop impacts on crop yields and economic returns evaluated at selected sites.
017 GROWTH REGULATOR EFFECTS ON HEIGHT CONTROL OF POTTED MUSSAENDA QUEEN SIRIKIT
Authors: Cramer Christopher S. , Bridgen Mark P. 
Published: February 2019

Mussaenda, a tropical ornamental shrub developed in the Philippines is being examined as a potential greenhouse potted crop in the United States. Showy sepals of white, picotee, pink or red and fragrant, yellow flowers make Mussaenda an attractive patted plans however, the profuse upright growth habit of some Mussaenda cultivars is undesirable for pot plant culture. With this in mind experiments were conducted to determine the effects of three growth regulators at two concentrations each, as well as the application method and the number of applications on Mussaenda plant height.
Three growth regulators, daminozide (B-Nine), ancymidol (A-Rest), and paclobutrazol (Bonzi) were applied at two commercially recommended rates and two application methods (spray or drench). The treatment were daminozide at 2500 ppm and 5000 ppm (spray), ancymidol at 33 and 66 ppm (spray) and at 0.25 and 0.50 mg/pot (drench), and paclobutrazol at 25 and 50 ppm (spray) and at 0.125 and 0.25 mg/pot (drench). In subsequent experiments, the same growth regulators were applied with an increase in concentration and either two or three applications. The treatments were daminozide at 5000 ppm (spray), ancymidol at 66 and 132 ppm (spray) and at 0.50 and 1.0 mg/pot (drench), and paclobutrazol at 50 and 100 ppm (spray) and at 0.25 and 0.50 mg/pot (drench).
The most attractive potted plants were produced with two applications of daminozide at 5000 ppm or two applications of ancymidol at 0.5 mg/pot (drench). Higher concentrations or additional applications excessively reduced plant height. Three spray applications of 132 ppm ancymidol also produced an attractive potted plant. Paclobutrazol sprays or drenches at any concentration or application number were ineffective for reducing Mussaenda `Queen Sirikit' plant height.
