The inhibition substances in Sorbus pohuashanensisHedl 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.

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。
