An investigation was undertaken to determine whether
potassium is indeed necessary for the in vivo synthesis of a
specific protein. The effects of univalent cations on the
inductive formation of nitrate reductase and on the level of
activity of representative non-adaptive enzyme are presented.
Cultures of Neurospora crassa were grown...
Three greenhouse experiments were designed to measure the
effects of N, K and Cl on the nutrient uptake by Russet Burbank potatoes
(Solanum tuberosum). A Deschutes sandy loam soil from Powell
Butte area in Central Oregon, low in potassium, was used to study
these effects.
Nitrogen applications produced significant increases...
Field experiments were conducted with cauliflower (Brassica oleracea var.
botrytis cv. Snowball Y ) to determine crop development, yield, quality and
maturity response to various seasonal water levels, and to specific water stress
timing in relation to curd initiation. The effects of nitrogen rate, timing, and
source and the application...
Reports of previous research indicated a stimulatory effect of
triazine herbicides on growth, yield and protein content of plants and
seeds of various species.
Studies were conducted in the greenhouse, laboratory and field
to investigate the effects of atrazine (2-chloro-4-ethylamino-6-a sopropylarnino-
s-triazine) on growth, yield, seed composition, and
seed germination...
