Variation of antioxidant content by capsule position in sesame

The study was conducted to provide basic information to breeder and agronomists working with sesame. Antioxidant contents, oil content and seed weight were investigated for two plant type identified and classified by branching habit. Changes of Antioxidant contents, oil content and seed weight as affected by capsule position in different plant type o sesame were estimated. Eight capsule positions, five on the main stem and three on the branches, were selected and the results obtained are as follows. The sesamin and sesamolin content of branch type was greatest at positions on the lower central part of the main stem and branches. The sesamin and sesamolin content of nonbranch type was greatest at positions on the upper bottom part of the main stem, the central part of the branch and smallest at the position on the top part of the main stem and branches. The oil content and seed weight was greatest at positions on the lower bottom part of the main stem, the bottom part of the branches. Non-branch type was better than branch-type in variation of sesamin and sesamolin content. Side capsule on main stem and branch were better than center capsule of main stem and branch in variation of sesamin and sesamolin content. The sesamin, sesamolin, oil content and seed weight of 4~9th node was shown lowest variation in comparison with those of other nodes.
