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...

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...

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...

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...

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...

Creator:: Wieneche, David L.
Abstract:: Temperate climates are particularly conducive to growth of annual bluegrass which readily invades and dominates most cool-season turfgrasses. Ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate) is one herbicide available which will selectively control annual bluegrass. The primary objectives of this research were to determine optimum application rates and timing of ethofumesate for control of...
