Mitigating Drought Stress of Korean Radish and Chinese Cabbage Through the Variovorax sp. YNA59 Treatment

Because of the recent abnormal climate, drought is severe worldwide. Drought stress causes ABA accumulation in plants, closing stomata, reducing gas exchange, and inhibiting photosynthesis. This, in turn, inhibits the growth and development of plants and leads to a decrease in yield, which has a major impact on the agricultural environment. Therefore, Variovorax sp. YNA59(hereinafter referred to as YNA59), a rhizobacteria that resist to drought stress was selected and inoculated into Korean radish and Chiness cabbage. In addition, the growth regulator Dadmi (paclobutrazol 0.39%(경농), hereinafter referred to as PBZ) known to be effective in drought was compared with the YNA59 treatment.
