【摘要】 对云南省西双版纳地区三叶橡胶 (Heveabrasiliensis(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～ 10 0 μgC·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 (IsopreneSynthase)缺乏所致。更多还原

【Abstract】 Based on the authors ’ investigation of the isoprene and monoterpene emissions f rom Hevea brasiliensis(H.B.K)Muell.-Arg in Xishuangbanna, it was found th at t he isoprene emission was low (emission factor varies between 0 and 1?μgC·g -1h -1) and the monoterpene emissions were high (emission factor varies between 10 and 100?μgC·g-1h-1). It was presumed that the scarcit y of the isoprene synthase in the chloroplast of hevea brasiliensis leaves d ominated the special emission character.更多还原
