Effects of Combined Inoculation of Pea Plants with Arbuscular Mycorrhizal Fungi and Rhizobium on Nodule Formation and Nitrogen Fixing Activity
نویسنده
چکیده
The response of pea (Pisum sativum cv. Avola) to arbuscular micorrizal fungi (AM) species Glomus mosseae and Glomus intraradices and Rhizobium leguminosarum bv. Viciae, strain D293 regarding growth, nodulation and nitrogen fixing activity was studied. Pea plants (Pisum sativum cv. Avola) were grown in a glasshouse until flowering stage (35 days) in 4 kg plastic pots using leached cinnamonic forest soil at low phosphorus level (60mg P2O5 kg soil -1). The obtained results demonstrated that dual inoculation of pea plants increased plant biomass, nodulation parameters, N2 fixation activity at varying levels compared to plants submitted to single inoculation with Rhizobium leguminosarum, strain D293, and depended on AM fungi species. Coinoculation increased significantly total P content in plant tissues and percentage of root colonization. Coinoculation efficiency of Rhizobium bacteria and Glomus mosseae was higher compared with Glomus intraradices regarding biological N2 fixation and AM colonization at the tested P concentration.

Nitrogen-fixing bacteria (rhizobia) form a nodule symbiosis with legumes, but also induce certain effects on non-host plants. Here, we used a split-root system of barley to examine whether inoculation with Rhizobium sp. strain NGR234 on one side of a split-root system systemically affects arbuscular mycorrhizal (AM) root colonization on the other side. Mutant strains of NGR234 deficient in Nod ...
