Abstract:

With the global environmental change and the irrational use of land resources, the issue of soil salinization is becoming increasingly serious, which casues a huge threat to agricultural production. Melatonin, as a small molecule substance widely existing in organisms, has received extensive attention in the study of crop stress physiology in recent years. In this paper, the research progress of the effects of melatonin on the physiological mechanism of salt and alkali tolerance of crops is reviewed, mainly from the latest research results of melatonin on crop growth and development, maintenance of ion balance, enhancement of antioxidant system, osmotic adjustment, improvement of photosynthesis and molecular level of transcriptome and metabolome, and the future research direction is explored, aiming to provide theoretical basis and technical support for the use of melatonin in improving the salt and alkali tolerance of crops.

Key words: saline-alkali stress, melatonin, crops, physiological mechanism, transcriptome, metabolome
