在自然条件下，通过盆栽试验研究了丛枝菌根真菌与菜豆丝核菌根腐病的相互作用。使用埃及配制的AM（Multi-VAM）混悬液混合物（浓度为1 × 10（6）单位L-1），稀释至5 ml L-1水。结果表明，AM真菌在菜豆植株上的定殖显著提高了菜豆的生长参数、产量参数和矿质营养浓度，降低了对这些参数以及病害严重程度和发病率的负面影响。不同的物理和生化机制已被证明在增强植物对立枯丝核菌的抗性中发挥作用，即改善植物营养、改善植物生长、增加细胞壁增厚、细胞质颗粒化和积累一些抗微生物物质（酚类化合物和防御相关酶）（C）2010 Elsevier GmbH。All rights reserved.
Interaction between arbuscular mycorrhizal fungi as a bio-agent and Rhizoctonia root rot disease of common bean plant was investigated in this study under natural conditions in pot experiment. A mixture of Egyptian formulated AM (Multi-VAM) in suspension form (1 x 10(6) unit L-1 in concentration) was used at dilution of 5 ml L-1 water. The results demonstrated that colonization of bean plants with AM fungi significantly increased growth parameters, yield parameters and mineral nutrient concentrations and reduced the negative effects on these parameters as well as both disease severity and disease incidence. Different physical and biochemical mechanisms have been shown to play a role in enhancement of plant resistance against Rhizoctonia solani, namely, improved plant nutrition, improved plant growth, increase in cell wall thickening, cytoplasmic granulation, and accumulation of some antimicrobial substances (phenolic compounds and defense related enzymes) (C) 2010 Elsevier GmbH.
