Abstract:

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.

Key words: tobacco, exogenous substance, abiotic stress, moisture, temperature, saline-alkali, heavy metal
