Effects of Durum Wheat (Triticum durum Desf.) Inoculation with PGPR (Azospirillum brasilense, Bacillus sp and Frankia CcI3) and Its Tolerance to Water Deficit

Abstract

Plant-growth-promoting rhizobacteria can improve plant growth, development and stress adaptation. However, the underlying mechanisms are still largely unclear. We investigated the effects of Azospirillum brasilense, Bacillus sp and Frankia CcI3 on durum wheat. Our study consisted in the evaluation of the interaction between rhizosphere microorganisms isolated from soils of different regions of Eastern Algeria and two varieties of durum wheat (GTA- dur and WAHA). Furthermore, our studies have also been carried out on the same durum wheat varieties under water deficit condition for the evaluation of the capacities of these PGPR in the restoration of their growth and in the increase of the production. The obtained results confirm the significant abilities of PGPR under these stress conditions for maintaining growth and plant survival.

Impact of Plant Growth Promoting Rhizobacteria in Restoring Soil and Crop Attributes

“…and P. polymyxahad significantly increased grain yield and dry matter content, N and P uptake (Silva et al, 2015). Benmati et al (2020) investigated the effects of Azospirillum brasilense, Bacillus sp. and Frankia CcI3 on durum wheat under water deficit conditions also.…”
