摘要
地球上大多数植物对病虫害的侵袭具有诱导防御反应。植物地上部与地下部之间存在着密切的生理生态关系，因此，地上部处理是否影响地下部的防御反应以及地下部处理是否影响地上部的防御反应，进而分别影响到地下部和地上部生物的行为成为当前研究的热点。本文系统地综述了地上部机械损伤、害虫取食、信号物质处理对植物地下部防御反应及生物行为影响以及地下部机械损伤、害虫取食、信号物质处理对植物地上部防御反应及生物行为影响的研究进展，并在此基础上提出了未来该领域值得进一步研究的方向，以期为深入研究植物地上部与地下部诱导防御间的相互关系提供科学依据。
Defense response can be induced in most terrestrial plants after they are attacked by disease and insects. On a basis of the close ecophysiological relationship between aboveground and belowground parts in plants, increasingly great attention has been paid to whether the treatment to the aboveground/belowground part in plants can induce the defense response in belowground/aboveground part, hence affecting the biological behavior of belowground or/and aboveground part. This paper summarizes the recent advances on the effects of mechanical damage, insect feeding and signal chemicals to aboveground/belowground part on the defense response and biological behavior in belowground/aboveground part in plants. Besides, future development direction in such fields is also put forward so as to provide a scientific foundation for in-depth studies on the interaction between the inducible defense response in aboveground and belowground parts in plants.
