Abstract

Hot water treatment at 60℃ for 10 min accelerated the germination of the seeds of japonica rice cultivars, Moeminori and Bekoaoba. Dry heat treatment at 50℃ for 7days decreased the germination percentage of Bekoaoba. However, hotwater treatment rather induced germination. It was suggested that hot water treatment was useful to improve the germinability of rice cultivars that were damaged by dry heat treatment. Hot water treatment also increased the germination percentage of the indica rice cultivars with strong dormancy, Takanari and Hokuriku193, though the promotion effect of germinability was weaker than that of dry heat treatment.
