毛竹叶及其竹鞭生化物质对杉木种子的发芽效应

通过杉木种子发芽试验,检测毛竹叶及竹鞭生化物质对杉木的化感作用;就总体而言,毛竹叶和竹鞭生化物质对杉木种子发芽有着一定程度的促进作用;毛竹叶及竹鞭非极性与极性生化物质的差异而言,毛竹叶及鞭弱极性生化物质对杉木种子发芽的促进作用强于极性生化物质。

Effect of leaf and root allelochemicals of Phyllostachys heterocycla cv. pubescens on germination of Chinese fir seed

Pinus massoniana seed germination was used to bioassary allelopathic of allelochemicals from Phyllostachys heterocycla cv.pubescens leaf and root to Chinese fir in this paper.The result showed that: As a whole,the allelochemicals of P.heterocycla cv.pubescens leaf and root had positive effect on Chinese fir seed germination;As far as the allelochemicals were concerned,litter-polar allelochemicals from P.heterocycla cv.pubescens leaf and root had positive allelopathic effect on P.massoniana seed germination.
