Many researches have showed that Outside stress has great inf uence on the growth and deve op ment of p ants. In this paper the studies of the bio ogica effects caused by stress on p ant in the domestic and abroad are reviewed. We first y discussed the macroscopica y bio ogica effects caused by environmenta stress stimu ation, . Second y the studies of bio ogica effects of p ant caused by environmenta stress stimu ation in the eve of ce s and mo ecu es are chief y expounded, main y inc uding the bio ogica effects caused by sing e ce oaded, e ectromagnetic, microgravity, u trasonic and strong sound, and some possib e mechanisms are in troduced and discussed. At ast, the research tendency of p ant perceiving stress is prospected. Key words p ant ce ; stress st imu ation ; bio ogica effects , , , , , 1 ,
