Abstract

One of the methods of priming is biopriming with growth promoting bacteria to increase seed germination and stimulate seedling growth. In this study, different effects of gamma ray on bacteria as mutants, irradiated (wild type) and control bacteria and then their effect on germination and vegetative traits of seeds were investigated. Seeds were selected from the legumes, cereal and garden plants. Experiments were conducted in a completely randomized design with 3 replications. The results showed that germination in the seeds had a positive reaction to the bacteria. But bean seeds had different responses to treatments. Reaction of different seeds to mutant and wild bacteria was different. Chickpeas achieved 100% germination with growth-promoting bacteria. Soybeans, flax, mung bean, wheat and lettuce had higher germination rates than controls. In the other measured vegetative traits, the bacteria showed different responses to the bacteria compared to the control and should be carefully studied for their use. But in general it can be said that all seeds increased in most of the traits compared to control and showed a positive reaction.
