Effect of some Plant Growth Promoting Rhizobacteria (PGPR) and Arbuscular Mycorrhiza Fungi (AMF) on Physiological Traits of Tareh Irani (Allium ampeloprasum L.)

Phosphate solubilizing and nitrogen-fixing bacteria and mycorrhizal fungi play an important role in the supply of nutrients in plants. To evaluate the efficacy of plant growth promoting bacteria and arbuscular mycorrhizal fungi (AMF) on physiology traits of Tareh Irani a field experiment in a randomized complete block design with 10 treatments and 3 replications was conducted. In this experiment tareh Irani seeds, (Tabriz landrace) inoculated with bacteria 1) P. putida P13, Pantoea agglomerans P5 (the biofertilizer Barvar2), 2) Azotobacter sp. (in biofertilizer Nitroxin), 3) bacteria Azospirillum sp. AC46 I, Azospirillum sp. AC49VП, 4) bacteria P. fluorescens Chao, P. putida Tabriz 5) two species of AMF, Glomus versiforme, G. intraradices. Results indicated that the colonization percent, percentage of chlorophyll, vitamin C content, total poly phenoles, phosphorus and nitrogen (p ≤ 0.01) and pyruvic acid, soluble proteins, (p ≤ 0.05) were affected by biofertilizers. Combination of mycorrhizal fungi and nitrogen-fixing bacteria (Azotobacter sp.) was better than other biofertilizer treatments in aspect of improving of quantity and quality traits in Tareh Irani. So that the bacteria can increase the efficiency of mycorrhizal fungi treatments were combined because of better nutrition and more food is especially phosphorus and nitrogen.
