Field and controlled environment chamber studies were carried out
to evaluate modes of action of post-harvest treatments on the development
and seed yield of cool season grasses. Red fescue (Festuca rubra
L.) was used as the primary test species.
There was no difference in total biomass production of red fescue...
Experiments were conducted to determine the effects of
certain plant regulatory chemicals on seed production of
alfalfa (Medicago sativa L.). Two plant regulators, SADH
(succinic acid 2,2-dimethylhydrazide) and TIBA (2,3,5-
triiodobenzoic acid), received particular attention.
Replicated field tests of the plant regulators were
carried out on the cultivar 'Talent' in...
The variable length, six-electrode plasma source for atomic
emission spectroscopy described here is operated from three
compact, simple, and inexpensive direct current power supplies. The
vertical arcs formed between the three electrode pairs completely
entrain the sample and are typically operated at 40 V and 20 A.
Three concentric quartz...
Developing sea urchin eggs (Strongylocentrotus purpuratus),
reared at 15° C, were subjected to single 15-minute treatments with
disodium versenate in calcium-free sea water, applied at 10-minute
intervals, from 4 minutes after insemination to the second cleavage.
These versene pulses produced specific degrees of retardation in
the mitotic process and delayed...
Taste responses of the Columbian black-tailed deer,
Odocoileus hemionus columbianus (Richardson), were determined
by use of the two-choice preference test method, where the choices
were tap water and tap water-chemical solutions in ascending
concentrations. The chemicals tested were: the sugars, glucose
and sucrose; the sodium salts of chloride (NaC1) and...
