摘要：

Fatty acid profiles, starch content and germination of watermelon seeds differing in seed vigour were determined for 4 triploid and 2 diploid lines. There were major differences in the fatty acid profiles between diploids and triploids. A major increase in the relative amounts of the unsaturated linoleic acid (C18:2) was found in triploids. Diploids had significantly higher starch levels than triploids. There was a high correlation between starch content and mean germination time. Conversions of seed storage reserves during early germination events may differentially affect seed vigour in triploid and diploid watermelon seeds.
