丛枝菌根真菌提高植物耐盐性的机理研究进展

Research Progress on Salt-Tolerant Mechanisms of Plants Enhanced by Arbuscular Mycorrhizal Fungi

土壤盐渍化是影响植物正常生长的主要因素之一,丛枝菌根真菌能提高植物的耐盐性。分析了土壤盐渍化对丛枝菌根真菌生长、发育的影响,重点从营养吸收、光合作用、根系、抗氧化防御系统和脯氨酸等5个方面阐述了丛枝菌根真菌提高植物耐盐性的机理。

Soil salinization was a factor affecting normal growth of plants.Arbuscular mycorrhizal fungi could improve the salt tolerance of plants.The effects of soil salinization on the growth and development of arbuscular mycorrhizal fungi was analyzed,and the possible mechanisms that arbuscular mycorrhizas enhance the salt tolerance of plants from aspects of nutrient uptake,photosynthesis,antioxidative defence system,root and proline were elaborated.
