| Abstract: | The grain-filling of rice is an important physiological process in rice growth and development,and affects directly the rice seed-setting rate and yield.The causes and mechanism of poor grain filling of super rice and the regulations approaches to increase grain plumpness of super rice were analyzed from grain-filling characters,hormones and enzymes.The aim was to reveal the metabolic mechanism of grain-filling of large-panicle rice varieties and provide theoretical basis for digging high-yield potential in super rice. |
