An Evaluation of the Oil Concentration in Sesame Seeds in Relation to Developmental Stage, Node Position and Capsule Age
Published online by Cambridge University Press: 03 October 2008
Summary
Weekly measurements were made of the seed oil concentration (% dry weight) in five sesame genotypes (Sesamum indicum) from flowering to maturity. During early but not late development the oil concentration of main shoot capsules was less variable than that in capsules taken from branches. The oil concentration of seeds from capsules at different nodes decreased from 67 to 22% between the lowest (oldest) capsule at node 8 and the youngest one at the uppermost node (25) in 1976, and from 65 to 19% for the same nodes in 1977. Variations in oil accumulation in relation to capsule age revealed that oil formation begins within 5 days after fertilization and maximum accumulation (52% oil) was achieved after 30 days. The implications of these findings for the assessment of oil yield potential are discussed.
