VA菌根营养生理研究概况及其应用前景

A review of the nutrient physiology of VAM and its potential application

菌根能促进植物生长,改良植物品质,增强植物抗性等,都与其对多种营养的吸收有关。本文从营养生理角度对VA菌根的研究进行了综述,包括VA菌根营养吸收特点、营养效应、吸收养分的机理、对养分的运输和传递,最后分析了VA菌根的生物学意义及其应用前景,指出VA菌根技术的深入研究与开发利用对我国农业可持续发展具有重大意义。

Many functions of Vesiculararbuscular mycorrhiza(VAM) such as accelerating the growth of plant seedlings,improving the quality of plant productions and strengthening the resistant abilities of plants are correlated to nutrientabsorption.The nutrient physiology of VAM is reviewed,including nutrientabsorption characteristics,nutrient effects,nutrientabsorption mechanism and nutrient transference.Biological significance of VAM and its potential application are also analyzed,and concluded that deep and thorough researches into VAM technical development are of great significance for our sustainable agriculture development in 21st century.
