Germination of immature (Stage III) and mature (Stage V) wheat (Triticum aestivum L. var. Chinese Spring and Yamhill) embryos is prevented by the inclusion of 10⁻⁴ M abscisic acid (ABA) in culture medium. In addition, Stage III embryos develop into mature embryos in culture medium containing ABA. In the absence...
Electrical stimulation of beef carcasses (n=18) did not cause a
significant reduction in microbial population on three different sampling
positions immediately following slaughter. In constrast, significant
microbial reduction (P > 0.05) was found at position 2 (muscle
above aitch bone), but not at position 1 (inside of neck) or position...
This seventh annual report outlines our continued progress on each of six
objectives.
Improved fumigants: We continue to evaluate previously established field
tests, which inlicate that chioropicrin continues to protect Douglas-fir poles
after 17 years and piling after 12 years. Vorlex treated poles are being
gradually recolonized by decay fungi,...
This fifth annual Cooperative Pole Research Program report
outlines our progress in the six project objectives.
Improved Fumigants
Sampling of previously established field tests revealed that
Vorlex and Chloropicrin continued to perform well after 15 years,
while Vapam was slightly less effective. Solid methylisothiocyanate
(MIT) also performed well in the...
After 14 years, chloropicrin, Vapam and Vorlex continue to effectively
control internal decay of pressure-treated Douglas-fir
transmission poles, but 6 years after application of methylisothiocyanate
(MIT) some poles are becoming reinfested by decay fungi
although NIT residues remain high in these poles. The closed-tube
bioassay, developed through our research, is...
Two experiments were conducted on wine grapes 'Chardonnay' and
'Gewurtztraminer' (Vitis vinifera L.) in 1986 and 1987 to
investigate the performance of grapes in competition with perennial
ryegrass (Lolium perenne L.) 'Manhattan 11' sod, the competition
between sod and grapes for nutrients and moisture and the effects
of nitrogen fertilization...
Rates of predation on artificial nests and nests of pen-reared
ring-necked pheasants (Phasianus colchicus), released in spring, were
compared between strip and block habitats at different densities of
nests. Nests in strips had rates of predation 4-7 times greater than
nests in blocks, regardless of nest density. Differences between
successful...
A small-scale test was developed to evaluate the ability of fungicides to control decay fungi established in wood. The test, which uses blocks 2.5 x 2.5 x 10 cm, tests the ability of a chemical to migrate from the middle of the block to control a previously established decay fungus,...
