Fig. 2.

(A) Abscisic acid (ABA) contents and (B) stomatal opening (%) in leaves of Chinese cabbages (‘Ryeokkwang’ and ‘Buram-3-ho’) at 24 h after heat and drought stresses treatment. Plants were drenched with strain H26-2 and H30-3, and 10mM MgSO₄ solution as untreated control, one week later, heat and drought stresses were performed. Error bars indicate the standard errors of eight (for ABA contents) or 16 (for stomatal opening) replications from two experiments. An asterisk on bars with error bars indicate significant (P < 0.05) differences between treatments according to the least significant difference test.
