Abstract :Cadmium insert ignore into journalissuearticles values(Cd); is one of the main elements that cause heavy metal pollution, which is one of the important types of environmental pollution. There is a constant quest to reduce or eliminate the effects of Cd pollution. Plant growth-promoting rhizobacteria insert ignore into journalissuearticles values(PGPR); is one of these possible solutions. PGPRs not only increase plant growth but also protect plants against organic and inorganic stresses. In this study, the effects of three different Pseudomonas strains insert ignore into journalissuearticles values(MS-7, MS-12, and MS-13); on morphological and pomological characteristics of three different strawberry cultivars insert ignore into journalissuearticles values(Rubygem, Kabarla, and YFL); exposed to three different Cd doses insert ignore into journalissuearticles values(0, 100 and 300 mg kg-1); were investigated to determine the effectiveness of PGPR against Cd toxicity in strawberry. To this end, root collar diameter insert ignore into journalissuearticles values(RCD);, root length insert ignore into journalissuearticles values(RL);, root fresh weight insert ignore into journalissuearticles values(RFW);, root dry weight insert ignore into journalissuearticles values(RDW);, shot fresh weight insert ignore into journalissuearticles values(SFW);, shot dry weight insert ignore into journalissuearticles values(SDW);, leaf area insert ignore into journalissuearticles values(LA);, mean fruit weight insert ignore into journalissuearticles values(MFW);, mean fruit length insert ignore into journalissuearticles values(MFL);, and mean fruit diameter insert ignore into journalissuearticles values(MFD); were examined. It was observed that the effects of different Pseudomonas strains were cultivar-specific and affected some parameters more. Rubygem MS-7 bacterial strain preserved SDW insert ignore into journalissuearticles values(3.21 g); and MS-12 bacterial strain preserved RFW insert ignore into journalissuearticles values(13.01 g); at 300 mg kg-1 Cd dose significantly better against Cd toxicity than other bacterial strains. In Kabarla MS-7 bacterial strain preserved RDW insert ignore into journalissuearticles values(3.72 g); at 300 mg kg-1 Cd dose and MS-12 bacterial strain preserved SFW insert ignore into journalissuearticles values(15.27 g); at 100 mg kg-1 Cd dose significantly better against Cd toxicity than other bacterial strains. Likewise, in YFL, MS-13 bacterial strains preserved MFW insert ignore into journalissuearticles values(7.509 g); and RL insert ignore into journalissuearticles values(30.00 cm); at 300 mg kg-1 Cd dose, and MS-7 bacterial strain preserved LA insert ignore into journalissuearticles values(57.87 cm2); at 100 mg kg-1 Cd dose significantly better against Cd toxicity than other bacterial strains. The results of the study showed that formulations containing Pseudomonas sp. can be used as an agricultural improver in areas with heavy metal pollution. As a result of the study, it was observed that PGPR applications were effective in preserving the morphological and pomological characteristics that decreased with the increase in Cd dose.
