摘　　要：概述了低温胁迫对植物质膜系统、保护酶系统和渗透调节系统的影响,探讨了外源化学物质调控烟草抗寒性的作用,认为利用外源化学物质提高实际生产中烟草的抗寒性是可行的。最后,提出了今后利用外源化学物质提高烟草抗寒性的重点研究方向。The effects of low temperature stress on plant cell membrane system, protective enzyme system and osmotic adjust-ment system were overviewed. The function of exogenous chemical compounds in the cold resistance regulation of tobacco was inves-tigated. It was feasible to improve the cold resistance of tobacco in the actual production through the use of exogenous chemical com-pounds. Finally, the key research direction of improving the cold resistance of tobacco by using exogenous chemical compounds was proposed.
