栝楼(Trichosanthes Kirilowii Maxim)种子发芽特性的研究

Studies on Germination of Trichosanthes Kirilowii Maxim

本文研究栝楼种子的发芽特性。结果表明栝楼种子具有休眠特性，其休眠原因由种皮障碍引起。用25～35℃变温发芽可打破其休眠，但浸种48小时的粘接种子产生二次休眠。栝楼种子的最适发芽条件是砂床、25～35℃变温。本文还提出了栝楼种子生活力的快速测定方法。

The seed of Trichosanthes Kirilowii Maxim is domant. The dormancy is caused by its seedcoat and can be broken by changing temperature (25 - 35 ℃ ), Seeds soaked in water (48hours ) go into second dormant state. The fittest germination condition is sand bed and changing temperature (25 - 35 ℃ ). The rapid testing method of seed viability of Trichosanthes Kirilowii Maxim is offered in this paper.
