摘要
水分、盐碱、温度和重金属等非生物逆境因子胁迫烟草的生长发育,研究发现外源物质在烟草逆境缓解中扮演十分重要的角色。文章归纳了非生物胁迫对烟草生长的不利影响,总结了外源物质缓解非生物胁迫的作用途径,分析了外源物质施用的最佳浓度,指出施用外源物质可能对烟草产生的不利影响,并指出了多种外源物质复配效果优于单一外援物质影响,同时展望了今后烟草非生物逆境研究的前景,以期为挖掘和应用新的外源物质以及阐明其缓解逆境影响的调控机制提供理论依据。
Abiotic stressors,such as water,saline-alkali,temperature and heavy metals,stress the growth and development of tobacco,and current research has found that exogenous substances play a very important role in tobacco stress mitigation.This paper summarizes the adverse effects of abiotic stress on tobacco growth,and the pathways of the action of exogenous substances in alleviating abiotic stress,analyzes the optimal concentration of exogenous substance application,and points out the possible adverse effects of exogenous substance application on tobacco.It also points out that the effect of multiple exogenous substances in combination is better than the effect of single exogenous substance,and discusses future prospects of tobacco abiotic adversity research,aiming to provide a theoretical basis for the exploration and application of new exogenous substances in tobacco cultivation and the elucidation of their regulatory mechanisms to mitigate the abiotic adversity.
