Abstract
Abscisic acid and gibberellin can regulate the growth of rice.In this study,effects of exogenous hormones on grain plumpness and quality of rice were analyzed by spraying ABA,GA3 and PR1(a mixture of GA3,triadimefon,naphthaleneacetic acid and potassium dihydrogen phosphate) 5 days before flower in field cultivation condition.The result showed that the thousand-grain weight of superior spikelets was enhanced 5.69%,4.67% and 8.27% by exogenous ABA,GA and PR1,respectively;the thousand-grain weight of inferior spikelets was enhanced 12.00%,7.67% and 13.89% by exogenous ABA,GA and PR1 respectively.The superior grains plumpness was enhanced 1.72%,1.12% and 1.20% by exogenous ABA,GA and PR1 respectively;the inferior grains plumpness was enhanced 9.71%,5.49% and 12.86% by exogenous ABA,GA and PR1 respectively.ABA and PR1 lower chalky rice rate,chalky area of grain and chalk degree,further more the chalky rice rate of superior and inferior grain highly significant differenced with the control.This study indicated that three exogenous hormones enhanced the thousand-grain weight and grain plumpness;ABA and PR1 lowered chalky rice rate,chalky area of grain and chalk degree.Exogenous hormones had greater effects on inferior spikelets than superior spikelets,and PR1 was better than ABA and GA3 to improve grain plumpness and quality of rice.
