| Abstract: |
| Biological water-saving agriculture mainly includes breeding of new cultivars, addition of exogenous beneficial substance and hormone, and establishment of efficient water-saving cultivation method. Trehalose, which is an oligosaccharide, is used as an exogenous beneficial substance in agricultural production. On the basis of comprehensive domestic and foreign related research literature, the properties of trehalose as well as their mechanism of improving plant resistance and the relationships between trehalose and stomatal immunity were analyzed. It is found that exogenous trehalose has nonspecific protective effect, which can effectively improve plant resistance and the ability to resist diseases and pests. In addition, trehalose can further enhance the drought resistance of crops by regulating stomatal development and stomatal movement. Thus, it is considered that trehalose has broad application prospects in biological water-saving agriculture, and it is an important way to improve the water use efficiency of crops. |
