Abstract:

Moringa oleifera Lam is tropical and subtropical fast-growing tree species. It has excellent resistance to high temperature,barrens,and drought. It is rich in nutrient and functional ingredients,and thus it can be used in various fields such as food,health product,and fodder. The changes of global environmental and human activities have aggravated abiotic stress. The resistances of M. oleifera to abiotic stress,including drought,low temperature,and salt,have been attracted growing attentions. At the same time,the extract from M. oleifera can be used as a safe and effective biostimulant for alleviating the damage caused by abiotic stress,promoting plant growth,increasing stress resistance,and improving the yield and quality of plants. In either the study of abiotic stress resistance of M. oleifera or the study of M. oleifera growth regulators,the resistances of M. oleifera plant and species as well as the improvements to the plant damages by the stress were evaluated by the changes of relevant parameters,such as morphology,yield and quality,osmoregulatory systems,protective enzyme systems,photosynthetic systems,molecular levels,etc. This review summarizes the research status in last few years on the stress resistance of M. oleifera and the application progress of its extract in the stress resistance of plants,discusses the existing issues,and proposes the research prospects,aiming to provide references for studying the stress-resistant breeding,the mechanism of stress-resistance,as well as the application research of inducing plant stress resistance.

Key words: Moringa oleifera, extract from Moringa oleifera, stress resistance, plant growth regulator
