(A) Growth promotion by Bacillus aryabhattai H26-2 and Bacillus siamensis H30-3 compared to 10 mM MgSO₄ solution (control) in Chinese cabbage (‘Ryeokkwang’ and ‘Buram- 3-ho’) under non-stress condition; (B) Leaf wilting score (0–5) under heat and drought conditions; (C) fresh weight after rewatering of Chinese cabbages (‘Ryeokkwang’ and ‘Buram-3-ho’). Plants were treated with bacterial strains H26-2 and H30-3, or 10 mM MgSO₄ solution (untreated control), one week later, heat and drought stresses were treated; Twenty-four h after end of stress treatment, fresh weight were assessed. Error bars indicate the standard errors of 20 replications from two experiments. An asterisk on bars with standard errors indicate significant (P < 0.05) differences between treatments according to the least significant difference test.
