Abstract

Flotation of raw baby lima beans (Phaseolus lunatus L.) in salt brines and flotation combined with sieve sizing were found to be reliable methods of segregating such beans into quality classes for evaluation and grading. The shearpress gave only a general indication of the over-all quality of a lot, since it did not facilitate segregation of individual beans.

Abstract

‘Thaxter’ and ‘Fordhook 242’ lima bean (Phaseolus lunatus L.) cultivars were subjected to climatic variables in controlled-environment cabinets to determine conditions which were adverse to their reproduction. High night temperature promoted flower opening but was deleterious to pod set and retention. High humidity increased pod set and retention, apparently by promoting good pollen germination. High humidity, however, was unfavorable when it was combined with high temperature. Low night temperature was unfavorable when it was combined with low humidity. The most favorable environment for pod set and retention consisted of high humidity, low night temperature, and high soil moisture. ‘Fordhook 242’ set and retained fewer pods under environmental stress than ‘Thaxter’.

Abstract

Cluster-thinning of the French hybrid grape cultivar ‘de Chaunac’ (Vitis sp.) resulted in superior fruit quality and an increase in vigor of the vines in comparison to the unthinned vines in a similar pruning and management regime. The higher sugar levels associated with thinning are consistently desirable for wine making under Ontario conditions. The favorable test site used limited the expression of vine decline and winter injury usually associated with over-cropping of this cultivar in the Niagara Peninsula of Ontario.
