摘 要:

硼不仅是植物生长必需的营养元素, 也可减少和降低植物病害的发生。本文总结了硼抑制植物病害发生的作用机制: 参与植物细胞壁和膜形成, 增强植物细胞稳定性; 诱导植物产生系统获得性抗性; 诱导植物细胞产生适量的酚类和过氧化物; 抑制病原菌菌丝生长, 扭曲病原菌菌丝结构形态; 破坏病原菌活性氧代谢系统, 加快膜脂过氧化作用; 与生防菌协同控制植物病害发生等。另外, 还探讨了矿质元素防治植物病害可能存在的问题以及应用前景, 以期为进一步的研究提供参考。

Abstract:

Boron is not only an essential nutrient for plant growth, and it can also reduce the occurrence of plant diseases. Here the inhibition mechanisms of boron on plant disease are reviewed in this paper. At first, boron is effective in enhancing plant disease resistance, involving in plant cell wall and membrane formation to enhance the stability of plant cell, inducing plant to produce systemic acquired resistance, and inducing plant cells to produce the right amount of phenols and peroxide. Moreover, boron could inhibit the growth of pathogen hyphae, distort the structure of pathogen hyphae, destroy the reactive oxygen metabolism system of pathogen, and accelerate the membrane lipid peroxidation. Last but not least, boron can be used with mixed application of biocontrol agents, cooperative control pathogens. In addition, the possible problems and application prospect of mineral elements on controlling plant disease are also discussed. Therefore, the review might provide the reference for further research.

Key words: boron; plant disease; inhibition mechanisms
