摘　　要：以冬青为试验材料,研究冬青种壳与种皮透水性及种皮内含物对冬青种子休眠的影响,结果表明:冬青种壳与种皮具有一定的透水性,能为冬青种子萌发提供必要的透水、透气条件.通过种皮浸提液对白菜种子发芽、苗高及根长生长影响的研究,表明冬青种子种皮中存在着抑制物质,这些抑制物质对冬青种子萌发起着一定的抑制作用.Holly seeds are used as test materials to study, study on the water absorption of seed shell and the biotic measurement to the dormancy. The result showed： The seeds can sop some water. In the examination of the germination of cabbage, we know there some inclusion in the seed capsule, what can restrain the bourgeon of the holly seed.
