Effect of high-temperature on the pollen viability of rice under high-temperature stress in the flowering stage. When exposed to high temperatures during the flowering stage, the number of pollens decrease sharply. It also triggered decreases in the rate of spikelet fertility and yield. Pollen viability decreased in both tolerant line and sensitive line during high-temperature treatment, but decreased more sharply in the sensitive line. Pollen grains were stained using I2-KI. Nagdong, CNDH22, CNDH71, and CNDH75 were tolerant to high-temperature, and Cheongcheong, CNDH11, CNDH48, and CNDH109 were susceptible to high-temperature. Scale bars, 100 μm
