花楸树果实浸泡液的萌发抑制作用

摘要/Abstract

摘要： 对花楸树种子形态及果肉、种子、去皮种子不同浸泡时间下的浸泡液对小麦和白菜种子发芽率及幼苗生长的抑制作用进行了研究。结果表明，花楸树果实果肉、种子、去皮种子浸泡液中均含有水溶性萌发抑制物质，不仅抑制小麦、白菜种子萌发，而且抑制其幼苗高生长和根的伸长。在几种浸泡时间中，浸泡8小时的去皮种子浸泡液对白菜、小麦种子发芽率的抑制作用最为明显，其发芽率分别为65%、89%，但随着浸泡时间的延长而降低；浸泡8h的果肉浸泡液对白菜和小麦幼苗高生长和根伸长的抑制作用最为明显，种子和去皮种子浸泡液(8h)的抑制作用对小麦和白菜的抑制作用次之，随着浸泡时间的延长，果肉浸泡液的抑制作用逐渐减弱，因而采收下来的果实及时净种是清除果肉水溶性抑制物质简单有效的方法。种子内部所含的一些成分是引起种子休眠及发芽率低的内因。

Abstract: Seed morphology and effects of water extracts of pulp, seed and decoated seed on germination of cabbage and wheat seeds were studied. The results showed that the pulp, seed and decoated seed contain soluble inhibiting substances and the content decreased as the increasing of soaking time. The inhibition substances in Sorbus pohuashanensis(Hance)Hedl fruit not only restrained the seeds of wheat, cabbage from germinating but also restrained height and root growth. After the seeds of wheat, chinese cabbage had been soaked in the water extraction of pulp, seed and decoated seed for 8h, the seed germination rates were 92% and 84%, 89% and 65%, 94% and 78%, lower than the control, especially the water extract of decoated seed; and the root length and seedlings height were lower than the control, especially the water extract of pulp, and decreased in sequence of soaking time from short to long. So the simplest and effective method to eliminate pulp soluble inhibiting substances is to wash fruits by flowing tap water soon after collection. The seed contains some substances that inhibit seed germination, and lead to low germination.
