Influence of canopy orientation on fruiting of 'Ànjou' pears and postharvest urea spray on ovule longevity and fruit set of 'C̀omice' pears

Creator:: Khemira, Habib
Abstract:: The effect of canopy orientation on fruiting performance of 'Beurre d'Anjou' pears (Pyrus communis L.) and postharvest urea spray on ovule longevity and fruit set of 'Doyenne du Comice' pears were studied. Hedgerows of 'Beurre d'Anjou' pear trees planted in 1969 in two orientations north-south (N-S) and east-west (E-W) were...

Isozyme banding patterns and embryo development in interspecific crosses of Phaseolus

Creator:: Guo, Mei
Abstract:: Interspecific hybridization between Phaseolus vulgaris and P. coccineus results in the formation of either mature F₁ seeds or abnormal embryos, depending on the direction of the cross. However, normal as well as abnormal embryos occur in the reciprocal F₂ populations. The exact cause of abnormal embryo development is unknown. To...

Development of in vitro lily scale budlets as related to virus elimination

Creator:: Ruttum, Joanne C.
Abstract:: Lily hybrids vary in their ability to produce virus-free (VF) bulblets when grown from virus-infected scales in tissue culture. Asiatic hybrids typically produce a higher percentage of in vitro VF scale bulblets than do Lilium longiflorum cultivars. Three hypotheses concerning the cause of this variation are tested on five lily...

Fall applied ethephon and temperature effects on flower bud growth and ovule longevity in Prunus domestica

Creator:: Moreno-Simunovic, Yerko M.
Abstract:: In the Pacific Northwest some prune cultivars often exhibit inconsistent fruit set. Several factors have been associated with this characteristic. Temperature, genotype and boron content are among the most frequently mentioned. Studies were conducted to determine the effect of fall ethephon application on flower bud growth and ovule longevity in...

Effects of inoculation with rhizobium and nitrogen fertilizer on snap beans, soybeans and lima beans

Creator:: Ma, Mei-hwa Wang
Abstract:: The responses of 'Oregon 1604' snap beans (Phaseolus vulgaris L.), 'Early Thorogreen' lima beans (Phaseolus lunatus L.), and 'Takii's Extra Early' soybeans (Glycine max L.) to two methods of inoculation with rhizobium (seedcoating and furrow treatments) and rates of nitrogen fertilizer were studied in field experiments. Nitrogen rates ranged from...

Effect of nitrogen fertilization of wheat (Triticum spp.) on chemical and biochemical composition and performance of seeds

Creator:: Garay, Adriel Edgardo, 1945-
Abstract:: High protein wheat seeds frequently perform better than low protein seeds of the same variety. Protein content of seeds can be increased by management practices, the most important of which is rate and timing of N applications. The purpose of this study was to determine the chemical, biochemical and physiological...

Relationships between endogenous phenolic compounds of rhododendron tissues and organs and cold hardiness development

Creator:: Chalker-Scott, Linda
Abstract:: The leaching of water soluble phenolic compounds from cold stressed Rhododendron leaves was found to be a reliable indicator of tissue damage. In sublethally stressed leaf tissues, more and novel phenolic compounds appeared and were hypothesized to be precursors of cell wall components such as lignin and suberin. Subsequent radiolabeling...
