对中国稀有濒危植物永瓣藤( Monimopetalum chinense Rehd.) 的自然营养繁殖特性进行了调查, 并进行了迁地保存及人工营养繁殖试验, 结果表明:( 1) 永瓣藤在自然生境中主要靠营养繁殖来维持种群生存, 但受其生境郁闭度的影响, 繁殖率较低。 ( 2) 人工扦插繁殖是永瓣藤生物多样性迁地保存的有效方法。 ( 3) 生根剂处理能提高扦插繁殖率, 尤以 ABT-1 的效果最佳。 ( 4) 压条繁殖是一种培育大苗的可靠方法, 但有一定的局限性。
 

This paper deals with the features of natural vegetative propagation of Monimopetalum chinense Rehd .The result reveals that :( 1 ) M .chinense population survival is maintained by vegetative propagation, but its propagational efficiency is low because of the effects of habitat crown density .( 2) Artificial cutting propag ation is an effective method of ex situ conservation of this species biodiversity .( 3) All the three rooting substances can raise propagational efficiency of its cuttage, in w hich ABT-1 has excellent result especially .( 4) Layering propag ation is a reliable means of breeding large sprouts, but existing some limitations.
