Interactive effects of Arbuscular mycorrhizal fungi and rhizobial strains on chickpea growth and nutrient content in plant

摘要

Legumes form a tripartite symbiosis with?Arbuscular mycorrhizal?fungi (AMF) and rhizobia. Chickpea plants were inoculated with six strains of?Mesorhizobium?ciceriand three AMF species,?Glomus?intraradices?(GI),?G. mosseae?(GM) and?G. etunicatum?(GE). The plants inoculated with a number of AMF species and bacterial strains increased overall plant dry mass compared to non-inoculated plants. GE was the most efficient in increasing plant dry matter. Individual AMF species were more effective than when mixed (GI+GM+GE). Bacterial treatments had increasing effect on root colonization by GI, GM and GI+GM+GE. The results revealed that dual inoculation with AMF and rhizobium enhanced?nitrogen, phosphorus, zinc, iron and copper content in??plants but these increasing effects was different between fungal and bacterial treatments.
