| 摘 要： | 为了研究拧筋槭种子深度休眠的原因，以拧筋槭种子为试验材料，采用甲醇浸提液提取种子的果皮、种皮及胚中抑制物质，研究各浸提液对白菜种子发芽率、苗高及根长生长的影响。研究表明，除30％种皮浸提液对白菜苗高生长略有促进作用外，各浸提液随着浓度比例的提高，对白菜种子的发芽率、苗高、根长生长及简化活力指数的抑制作用都逐渐增强。各浸提液浓度比例相同的情况下，胚的甲醇浸提液对白菜种子的发芽率、苗高、根长的生长抑制活性最强，果皮和种皮次之。说明拧筋槭种子的果皮、种皮及胚中均含有一些抑制物质，这些抑制物质的存在可能是拧筋槭种子休眠的主要原因之一。

| Abstract: | To study the reasons for dormancy of Acer triflorum, seed germination and seedlings growth of Brassica campestris in different concentrations of the methanol extract from Acer triflorum seed coats, pericarp and embryo were study in order to investigate the relationship between the restraining substraces in seed coat ,pericarp and embryo in dormancy of Acer triflorum. The results showed that with the extract concentration increased ,the inhibitory effects of Brassica campestris seed germination rate,seedling shoot elongation,stem length and simplified vigor index were gradually increased except the 30% pericarp methanol extract. In the same concentrations, the inhibitory effect of the embryo was relatively strong, the pericarp and the seed coat were relatively weak. It is concluded that the inhibitors were distributed in all fractions of the seeds,and the existence of inhibitors in components of Acer triflorum seeds is the main cause of dormancy of Acer triflorum seeds. |
