Abstract:

Triazole fungicides have double functions in the agriculture. In addition to be the efficient and harmless specific fungicides, they also have function as non-traditional plant growth regulators which protect plants against various environmental stresses. In this paper, the specificity and superiority of triazole fungicides have been clarified by summarizing the regulatory function to plants growth and their influence on promoting stresses tolerance of plants including enhancing plant photosynthesis and the anti-oxidation potential, improving cell membrane lipid stability and the level of ABA. Triazole fungicides have resistance to various environmental stresses efficiently by promoting plant photosynthesis, improving the concentration of antioxidants including enzymatic and nonenzymatic, decreasing the level of MDA, increasing the accumulation of proline, and enhancing the level of ABA. There are scanty reports on the molecular mechanism of fungicides promoting plants stress resistance. Thus valuable references for the research and development of novel agriculture chemicals will be provided.
