摘　　要：维生素E是人和动物必需维生素。本文以2 0份向日葵种质资源为实验材料,通过对维生素E含量、含油率、皮壳率以及百粒重的测定及统计分析,试图了解向日葵种质资源中维生素E含量变异及相关数据。结果表明,在2 0份向日葵种质资源中,油葵的维生素E含量和含油率明显高于食葵;含油率与维生素E含量在0 0 1水平呈极显著正相关,含油率与百粒重在0 0 5水平呈显著负相关;百粒重与皮壳率在0 0 1水平呈极显著负相关。通过初步评价,发现3份富含天然维生素E的向日葵种质资源。Vitamin E is essential to human being and animal. Primary evaluation of 20 sunflower （Helianthus annuus L. ） seeds was carried out with the characters of vitamin E content, oil content, hull content and 100-seed weight. The results showed that vitamin E content of oil sunflower was significantly higher than that of confectionary sunflower. Vitamin E was correlated with oil content positively at 0.01 levels. Oil content and hull content affected 100-seed weight with a significant negative correlation at 0.05 and 0.01 levels, respectively. Three valuable germplasm were selected for sunflower breeding to improve vitamin E content.
