Purple nutsedge [Cyperus rotundas L.) has been recognized as one of the
most troublesome perennial weeds of agricultural lands in tropical and some
temperate regions. This research sought to determine the effects of timing of
herbicides, shading, and soil moisture on plant population growth and tuber
production of purple nutsedge...
This thesis concerns the alteration of the course of selective
protein synthesis and morphogenesis in plants treated with growth
regulating chemicals. Treatment of 48-hour-old "Alaska" pea seedlings
(Pisum sativum L.) with 2, 4-D, IAA, NAA or picloram caused
inhibition of epicotyl and primary root elongation and proliferation of
massed lateral...
The energy absorbed by microscopic volumes exposed to ionizing
radiation is not well represented by the average dose due to the small
number of discrete energy transfers involved. The energy deposited in
a microscopic volume can be determined by measuring the ionization in
a detector filled with gas at low...
