Abstract

Drought stress is an important growth limiting factor for crop plants e.g. wheat. Large arable areas of Iran, where wheat is the main staple food, undergo drought stress. Therefore, it is necessary to investigate practical methods for increasing the yield of wheat in these conditions. Many plant growth promoting rhizobacteria (PGPR) contain 1-aminocyclopropane 1-carboxylate (ACC) deaminase enzyme that can convert the ACC, the immediate precursore of ethylene in plants, to ammonia and a-ketobutyrate and cause decrease in stress ethylene. In this greenhouse research, the effects of two strains of Sinorhizobium meliloti KYA40 and KYA71 that contain ACC DEAMINASE enzyme and KYA95 (without ACC DEAMINASE enzyme activity, used as a negative control) were investigated on growth and nutrients uptake of wheat under different levels of water stress. in a factorial randomized complete block design (RCBD). The water treatments consisted of d0=40-60% available water (AW), d1=20-30%AW, and d2=5-15 % AW. The results showed that inoculation with KYA40 strain increased the shoot length, shoot weight, root length, leaf area, and potassium uptake of wheat. The KYA40 strain increased the shoot weight in treatment d2. Strain KYA71 increased Cu and Mn uptake in treatment d0.
