The need for field and laboratory studies of the physical and
chemical behavior of environmentally significant organic molecules often
poses problems because of the toxicity of the chemical and the difficulty
of detecting it at environmentally significant concentrations.
Two dysprosium tracers, dysprosium (III) trisacetylacetonate trihydrate
and dysprosium(III) trisdibenzoylmethane monohydrate, were...
The focus of this study was to determine if S₁ family recurrent
selection might be successfully used for barley improvement.
Objectives were: 1) to identify suitable methods of evaluating grain
yield in small plots, 2) to study the effects of intermating on mean
values and variances of selected agronomic characters,...
Cell aggregate size in both Douglas-fir and poplar suspension cultures was reduced by the addition of the chelator compounds EDTA and CDTA at concentrations under 100 ppm. Reduced cell aggregate size increased growth efficiency of suspension cultures of both species. Cell aggregates 550 j.z. or smaller in size were used...
