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...
Computer decision aids can help integrate and apply diverse sources of information and expertise to problems of integrated pest management (IPM) in agriculture and forestry. AppleMgr combines a rule-based expert system with databases and spreadsheets in a prototype decision aid intended to be expanded and modified for use by extension...
Under defined cultural conditions, large populations of zygotes
of the brown algae Fucus vesiculosus L. and F. distichus L. Powell
synchronously form a cell wall shortly after fertilization. Intact cell
walls, free of cytoplasm and maintaining shape properties of early
stages of embryo development, have been isolated from these zygotes....
Size and color are important visual quantity attributes of the fruit of strawberry (Fmgaria x ananassa Duch.). Strawberry cultivars produce fruit of a characteristic size and color, the later being the result of accumulation of particular anthocyanins. This research sought to determine the basis for genotypic differences in fruit size...
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...
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...
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...
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...
