Effect of Variety and Growth Conditions on the Ability of Moist Oat Caryopses to Hydrolyze Triglycerides.

Nine early and 11 midseason oat cultivars grown at 18 locations in the central and eastern United States were used to evaluate the ability of whole moist caryopses immersed in soybean oil to hydrolyze the oil. Significant differences in cultivars for mean of percentage hydrolysis were observed in both early and midseason groups. Percentage hydrolysis was correlated negatively with groat percentage for both early and midseason oat cultivars. Percentage hydrolysis was negatively correlated with the caryopsis weight for early cultivars. Oat caryopses harvested 15 days postanthesis had greater hydrolytic activity per unit weight than those harvested 30 days postanthesis. The hydrolytic activity of oat line B605-1085 varied significantly from year to year and was markedly higher in 1988, a very dry year.
