Studies on dormancy and germination of rice seed. 8. Temperature treatment effects on rice seed dormancy and hull tissue degeneration in rice seed during the ripening period and after harvest


Bulletin of the Faculty of Agriculture, Kagoshima University (29): 21-32
Studies on dormancy and germination of rice seed. 8. Temperature treatment effects on rice seed dormancy and hull tissue degeneration in rice seed during the ripening period and after harvest
Rice Ketaktara was subjected to natural conditions or temp. of 25 deg or 30 deg C for various periods from flowering to harvest at a seed m.c. of 20%. Seed dormancy was investigated at 10-day intervals after harvest. Dormancy of seed ripened at 30 deg was lower than that of seeds ripened in natural conditions, while dormancy tended to be increased in seeds ripened at 25 deg. The level of germination inhibitors was lower in seed ripened at 30 deg than in seed ripened at 25 deg.
