Abstract
Abstract Thirty‐six lots of eight Cuphea species grown at nine geographical locations from 1983 to 1985 were analyzed for seed weight, oil percentage, fatty acid and crude protein content. Twenty‐two samples were separated into two distinct seed maturity groups and also analyzed. Seed maturity varied widely but had little effect on oil percentage, even though mature seeds were significantly heavier than less mature seeds. Lauric acid content generally increased and capric acid decreased with increasing seed maturity. Crude protein of whole seeds and defatted seed meal increased with increasing seed maturity. The net effect of harvesting Cuphea wrightii seeds at full maturity in comparison with that for less mature seeds was to increase seed weight by 12%, decrease capric acid by 3%, increase lauric acid by 2% and increase crude protein of whole seeds and defatted meal by 5% and 4%, respectively. Seed oil content was decreased by a statistically nonsignificant 1%. The effect of seed maturity was comparable for the other four lauric acid‐ and three capric acid‐rich species, even though distinct species differences in all factors were measured. Location and environment contributed to some quantitative and qualitative changes, but these factors are not considered to be major sources of variation. It is concluded that variation in seed maturity does not present a major constraint to commercialization of Cuphea as a new, alternative source of lauric and other medium‐chain fatty acids. The ultimate significance of these minor changes will depend upon relative yields, demands and values of the various seed components.
