【摘要】 水稻籽粒灌浆是水稻生长的重要生理过程,直接影响到水稻的结实和产量。强、弱势粒异步灌浆往往导致结实率降低和产量下降。其生理活性是影响灌浆的重要因素,主要包括蔗糖合成酶类和淀粉合成酶类等的活性。同时,ABAI、AA、ALA和Z+ZR等激素以及CO2、温度和水分等外界环境因子对籽粒灌浆有着较大的影响。综述了籽粒灌浆的研究进展,并提出了今后加强不同因子对籽粒灌浆影响的深入研究。更多还原

【Abstract】 The grain-filling of rice is the important physiological process in the paddy rice growth,and affects directly the rice seed setting rate and yield.The superior and inferior grains asynchronous filling often causes a decline in them.Their biological activity is the important factor which affects the grain-filling.They include activities of sucrose synthase and starch synthesis enzymes.Meanwhile,some hormones and environmental factors have profound effects on grain-filling.In this article the aspects mentioned above about grain-filling of rice were reviewed and it was pointed out that some further studies on effects caused by various factors on grian-filling should be strengthened.更多还原
