The effects of five cytokinin antagonists on the growth
of cytokinin-autonomous lines of Phaseolus lunatus cv.
Kingston, Phaseolus vulgaris cv. Great Northern, and
Nicotiana tabacum cv. Wisconsin 38 callus tissues have been
compared. The antagonists tested included four N⁴-substituted 4-amino-2-methylthiopyrrolo[2,3-d]pyrimidines
bearing the following N⁴ side chains, 4-n-pentyl-
(ms²pnN⁴Prp), 4-n-hexyl- (ms²HxN⁴Prp),...
Paired 30-day trials were conducted to evaluate
Agropyron spicatum germination when treated with two
concentrations of throughfall leachates from western
juniper slash in two stages of decomposition. Data from
a second pair of 49-day greenhouse trials were analyzed
to evaluate emergence and growth of Aqropyron spicatum,
Oryzopsis hymenoides, and Poa...
Behavior of grizzly bears (Ursus arctos) toward people was
studied by examining hikers' reports of grizzly bear observations
and by intensively observing grizzlies in an area of Glacier National
Park that was heavily used by day-hikers. Of concern were the apparent
habituation of grizzly bears to people in the study...
Interactions between Bacillus sphaericus and Bacillus
thuringiensis israelensis (Bti), persistence of insecticidal
activity in the mosquito habitat, and suitability of enzyme-linked
immunoabsorbent assay (ELISA) for detecting and
quantifying bacterial endotoxin in the mosquito habitat were
investigated. Interactions between the two bacterial
species were examined by laboratory and field bioassays with...
Methylthioadenosine (MTA) is a naturally occuring nucleoside formed during
the synthesis of polyamines in mammalian cells. MTA is rapidly catabolised
by MTA phosphorylase (MTAase), eventually yielding methionine and
adenine. MTAase has been shown to be active in all normal cells, but
deficient in some cells and tissues of malignant origin....
Results of a study of spatial and temporal utilization of a tidal river estuary by hatchery and wild juvenile salmonids
(Oncorhynchus spp. and Salmo spp,), of overlap in food habits of hatchery and wild juvenile salmonids, and of size and relative
abundance of associated fish species are reported in this...
