Changes in of ABA, H2O2, and heat shock proteins in leaves of rice plants under heat stress. a, ABA content; b, H2O2 content; c, Relative expression level of HSP71.1; d, Relative expression level of HSP24.1. Vertical bars denote standard deviations (n = 3). A t-test was conducted to compare the differences between control and heat stress within a cultivar on the same day. * denotes P < 0.05
