Concerns regarding the most effective means of evaluating
segregating generations of spring barley prompted this investigation. Three methods of selection were considered: bulk, pedigree, and single seed descent. F₆ lines derived by each method
were grown in a replicated yield trial. The effectiveness of each
method was measured in terms...
The purpose of the present study was to investigate the effect
of a number of physical and chemical attributes upon muskmelon
texture as described by sensory evaluation. Measurements of turgor
pressure, percent moisture, total sugars, alcohol-insoluble-solids,
three pectic fractions, total pectic materials, starch and cellulose
were performed on 50 melons....
The volatile components of rye flour were isolated
by steam distillation and trapped in cold traps under
vacuum. After preliminary tests indicated the presence
of carbonyl compounds, the distillate was reacted with
2,4 dinitrophenylhydrazine to convert the carbonyl compounds
to their stable derivatives, 2,4 dinitrophenylhydrazones.
Three classes of monocarbonyls were...
