摘要/Abstract

摘要： 对云南省西双版纳地区三叶橡胶（Hevea brasiliensis（H.B.K）Muell.-Arg）异戊二烯和单萜烯排放的研究发现，三叶橡胶排放很少量的异戊二烯（排放速率大约0～1μgC·g^-1h^-1），而排放大量的单萜烯（排放速率大约10～100μgC·g^-1h^-1）。造成这种排放特征的原因可能是橡胶树树叶叶绿体中合成异戊二烯所必需的异戊二烯合成酶（Isoprene Synthase）缺乏所致。

Abstract: Based on the authors investigation of the isoprene and monoterpene emissions from Hevea brasiliensis (H.B.K) Muell.-Arg in Xishuangbanna, it was found that the isoprene emission was low (emission factor varies between 0 and 1μgC·g^-1h^-1) and the monoterpene emissions were high (emission factor varies between 10 and 100μgC·g^-1h^-1). It was presumed that the scarcity of the isoprene synthase in the chloroplast of hevea brasiliensis leaves dominated the special emission character.

Key words: Hevea brasiliensis (H.B.K) Muell.-Arg, isoprene, monoterpenes, isoprene synthase
