A study was made on the effect of CCC (2-chloroethyl)-trimethyl-ammonium
chloride), a plant growth retardant, on the RNA (ribonucleic
acid) content of wheat plants, It was found that the RNA content of
wheat leaves generally decreased with increasing levels of CCC up to
1x10⁻⁵M. Thereafter, the RNA content again increased...
The effect of soil temperature and soil water suction on the rate
of phosphorus uptake and growth rate of wheat (Triticum aestivum
VILL. ,
Host) was studied.
Plants were grown in perlite slabs
separated from an osmotic solution by a semi-permeable membrane.
Measurements were made at temperatures of 10.0, 18.3,...
The purpose of this study was to evaluate the effect of seed
protein content on plant growth of barley (Hordeum vulgare L. )
and wheat (Triticum aestivum L. ). The effects of nitrogen application
on chemical and morphological characteristics of the seed
were also studied.
Seeds of 'Casbon' winter barley...
The need to develop a shorter life cycle wheat cultivar which
would be more adapted to multiple cropping systems prompted this
study. Thus the following information was obtained.
Greatest variations in developmental patterns were found in the
stem elongation, booting, inflorescence emergence and anthesis for
five winter and five spring...
Increases in wheat production due to breeding may be reaching
a plateau. The application of N-fertilizer beyond optimum levels
leads to lodging and to an increase in tiller death. The use of
plant growth regulators (retardants) may be an answer for future
increases in production.
Experiments were conducted in 1983...
The effect of four basic liquid fertilizers: Solution 32, 10-34-0-.9, Thio-Sul, and Potash solution; and one commercial liquid fertilizer, Feast 9-18-9, on germination, emergence, and seedling growth of wheat (Triticum aestivum L.) were evaluated under laboratory, greenhouse, and field conditions. Experiments included: 1) preliminary study of basic fertilizer sources to...
An understanding of the effect of environment on
phyllochron (degree-days between two successive leaves) is
necessary to model cereal crop canopy growth. This study
was designed to investigate the relationships of phyllochron
to temperatures and daylengths in winter wheat (Triticum
aestivum L.) and spring barley (Hordeum vulgare L.). A
series...
No-tillage winter wheat (Triticum aestivum L.) grown in a
wheat-fallow cropping system has consistently produced lower grain
yields than conventionally tilled soils in the semiarid Pacific
Northwest. A 2-year study was conducted in a long-term tillage trial
at Moro, OR to determine factors responsible for differences in wheat
growth and...
