From: Salicylic acid reverses pollen abortion of rice caused by heat stress
The changes in pollen viability, MDA and H2O2 of rice plants sprayed with H2O, SA, DMTU, H2O2, and PAC along or together under control and heat stress. A-(a-j), the photos of pollen grains was stained with 1% with KI/I2 by a microscope (Leica, DM4000). A-(a-e), pollen grains under control condition. A-(f-j), pollen grains under heat stress condition. B-a and B-b, MDA and H2O2 at anther respectively. The data in the Fig. (A-k) were shown as the mean of ten replicates and Fig. (B-a and b) were shown for three replicates. DMTU, dimethylthiourea, an H2O2 and OH· scavenger. PAC, paclobutrazol, a SA inhibitor. Different letters indicate significant differences between treatments under control and heat stress (P < 0.05)
