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.
The experiment was conducted to study the effect of holocarp and seed coat on the water permeability and the content of seed coat on the dormancy of holly seed. The results showed that the holocarp shell and seed coat had certain water permeability and could provide the necessary for the germination of holly seed Permeable and breathable condition.The research on the effect of seed coat extracts on the seed germination, seedling height and root length growth of Chinese cabbage showed that the inhibitory substances existed in the seed coat of holly seed, and these inhibitory substances inhibited the seed germination of holly seed effect.
