| 摘 要： | 研究不同类型水稻籽粒灌浆特性及其与内源激素的关系结果表明,籽粒灌浆前期强势粒灌浆速率均高于弱势粒,后期则相反。新株型稻“IR_(65600-85)”强、弱势粒属异步灌浆型,导致弱势粒充实度更差。籽粒灌浆过程中内源激素含量变化为灌浆前期强势粒IAA及ABA含量较高,ABA/IAA、ABA/GA_(1 3)和ABA/(IAA GA_(1 3) ZR_S ABA)值均较高,而弱势粒则相反,尤以“IR_(65600-85)”弱势粒更突出,籽粒充实度最差,结实率较低。

| Abstract: | The difference of grain filling on sink basis and the related endogenous plant hormones contents of rice are studied with different types of rice.The results show that the superior grains of rice in each entry have higher grain-filling rates than the inferior grains and it is contrary in the late grain-filling stage.Among the three rice cultivars concerned,the superior-inferior grains of "IR65600-85" are an asynchronous grain-filling type,in turn leading to much lower grain filling in the inferior grains.Analyzing from the hormones of grains,the superior grains perform higher contents of IAA and ABA,higher ratios of ABA/IAA,ABA/GA1 3 and ABA/(IAA GA143 ZRs ABA) than the inferior grains in each entry during the early stage of grain-filling.The situations in the inferior grains are contrary,especially those in "IR65600-85",therefore they show lower grain filling and percentage of filled grains. |
