植物VOCs信号是植物间进行信息交流的“语言”, 可由多种生物和非生物因素诱导产生。非寄生植物释放的VOCs信号可影响其所在群落中其它植物的种子萌发与幼苗生长; 而寄主植物释放的VOCs信号却是诱导寄生植物种子萌发和幼苗生长的信号物质。VOCs作为植物间的伤害信息可以诱导临近的同种或异种植物做好防御准备, 从而通过主动或间接防御以减少外界的伤害。植物间通过VOCs信号进行信息交流, 从而实现其繁衍与防御。该文通过对VOCs信号的种类、诱导产生因素、传递及作用进行综述, 以期对VOCs信号的研究有所帮助。

Plant volatile signal is the language used in plant-plant communication and can be induced to be released by many biological and abiotic factors. Volatile signaling influences the seed germination and seedling growth of other plants in the community for non-parasitic plant. However, the volatile organic com-pounds (VOCs) from the host plant can induce seed germination and seedling growth of the parasitic plant. With the “hurt” message, VOCs can induce defense in neighboring homogeneous or heterogeneous plants, so they can reduce the hurt by direct or indirect defense. Plants communicate with others using a volatile signal, so their progenitive and defensive strategies can be realized successfully. To aid in helping the study of volatile signals, this review summarizes the kinds, inducing factors, transmission and functions of volatile signals among plants.
