The ROS level in the pistil under heat stress sprayed with NAA or AOPP. a-l the fluorescent images of pistil in NPB (a-f) and HTS (g-l) under natural and heat stress conditions; m and o show the average ROS levels, under heat-stress and natural conditions, in the NPB pistil and HTS pistil, respectively; n and p show the relative ROS levels, under heat stress and natural conditions, in the stigma, style and ovary of NPB and HTS, respectively. The levels of ROS in the three components of the pistil, the stigma, style and ovary, were found to be different. Vertical bars denote the standard deviation (n = 10). Different letters indicate significant differences between control and heat-stress treatments (P < 0.05)
