摘要: 异戊二烯为植物挥发的众多有机碳氢化合物中的主要成分,它的合成和释放对全球尺度上的C素平衡、温室效应和大气污染都有极其重要的作用.本文系统论述了影响异戊二烯释放的主要因子,异戊二烯的释放量及其计算方法,以及它可能的生态意义,指出了研究多重环境胁迫与异戊二烯合成和释放的关系的必要性.

关键词: 异戊二烯, 植物释放, 环境胁迫, 生态意义

Abstract: Isoprene is the main component of numerous volatile hydrocarbons emitted by vegetation. Its biosynthesis and e-mission from vegetation plays an important role in global carbon balance, greenhouse effect, and atmospheric pollution. In this paper, the main factors determining isoprene emission rate, isoprene emission amount and its calculation methods, as well as its potential ecological functions were reviewed. The importance of further study on the relationships between multiple stresses and isoprene biosynthesis and emission was emphasized.

Key words: Isoprene, Plant emission, Environmental stress, Ecological significance
