树胡椒繁殖后代叶油及成分的变化

Variations in Chemical Components of Leaf Oil from Reproductive Progenies of Piper hispidinervum

富含黄樟素的树胡椒 (Piperhispidinervum)无性后代扦插树叶油化学成分保持着母本的特性 ,主成分黄樟素含量无明显的变化、其它成分基本一致。有性繁殖后代实生树叶油成分发生了很大的变化 ,成分比母树复杂 ,主成分黄樟素低 ,仅为 32 .2 0 %— 4 1.95 % ,而肉豆蔻醚 (2 1.5 5 %— 2 9.4 1% ) ,肉豆蔻醚异构体 (8.0 8%— 10 .6 2 % )、芹菜脑 (4.6 0 %— 6 .74 % )、c- β -罗勒烯 (1.0 9%— 2 .37% )等在母树叶油中未发现。

The chemical components of leaf oil from cutting seedlings through vegetative propagation of Piper hispidinervum C.DC, which is rich in safrole keep the features of the parent, i.e. the content of the main component, safrole, is without obvious variations and other components are almost the same as those of the parent. However, the leaf oil components from seedlings through sexual reproduction are quite different from thoes of the parent and the main component, safrole' content is much lower,32.20%～41.95% only, myristicin (21.55%～29.41%)?apiol(4.60%～6.74%)and c-β-ocimene (1.09%～2.37%)which haven't been found in the leaves of the parent have not been gotten from the sexual reproductive progenies.
