Drought is a major factor limiting agricultural crop productivity by decreasing water availability of plants, worldwide. In drought, it is usually presented by the simultaneous action of high temperature and drying. The aim of this study was to know the effect of drought stress tolerance by plant growth promoting rhizobacteria (PGPR) on high temperature and water shortage stress of leafy vegetables; Angelica acutiloba Kitagawa, Brassica juncea L., Brassica oleracea var. alboglabra Bailey. The YP2 strain was isolated from rhizosphere soil of tomato plant in Yangpyeong, Korea and the isolate was identified as Bacillus velezensis based on molecular analysis. As a result, the YP2 strain significantly promoted the growth of A. acutiloba seedlings in increasement of about 43.3% of plant height, 69.8% of root diameter compared to control. There were also significantly increased, compared with control, 36.7% of leaf area in Br. juncea seedlings as well as 26.7% of plant height and 41.4% of fresh weight in Br. oleracea seedlings. In addition, B. velezensis YP2 was also found to be effective for mitigation of high temperature stress (66.8%, at 35℃) and water shortage stress (72.9%, at 14th day after non water-treatment) compared to control. These results suggest that YP2 might be used as a good method for improving quality and productivity of leafy vegetables under drought stress conditions.
