褪黑素在植物抵御逆境胁迫过程中的作用.

Studying the role of exogenous substances in plant stress resistance physiology is of great significance for agricultural production. Melatonin, as a new-style plant growth regulator, has played an important role in plant defense against adversity stress. The article reviews the latest research on melatonin in plant drought resistance, salt alkali resistance, cold resistance, and heavy metal resistance in recent years, and looks forward to future research hotspots, in order to provide information reference for related research in the future.
