Abstract: Drought and salt are abiotic stresses which affect plant growth and productivity, it is very important to research the drought and salt resistant mechanism for agricultural production and ecological building. Plant could change the osmotic substances and protective enzyme activity to improve the ability of drought and salt tolerance when suffered drought or salinity-alkalinity stress. Many genes related to plant drought and salt tolerance had been cloned and analyzed, and inserted to plant genome via transgenic technology, which could improve the ability of drought and salt resistance. This paper summarized the mechanism of drought resistance and salt tolerance from plant morphology, physiological and biochemical index, active oxygen scavenging and transcription factors and so on.
