摘　　要：野生保护被子植物存在共同的特点就是更新困难,数量稀少。我国重点保护野生被子植物有66个科190多种。选取了国家重点野生保护植物种中的12种植物,对这些植物种子的生理基础研究表明,这些植物普遍存在种子活力低的问题;绝大多数野生保护被子植物的种子存在休眠现象,新生幼苗对生境的适应能力差。这些是导致更新能力差的主要原因。Endangered plants of angiosperms is characterized by the common update problems.The conservation of wild flowering plants ,there are 66 families and over 190 kinds of plants focused in China.12 kinds of national key protected wild plant species were selected,plant seeds of the physiological basis of them showed that these plants widespread the problem of low seed vigor; the vast majority of wildlife existence of dormancy of seeds of angiosperms, newborn seedlings could not be adapt to poor habitat.These are the main reasons leading to poor updates.
