| 摘 要： | 在大田条件下．以汕优63为对照，分析了超级稻玉香油占、胜泰1号和准两优527的产量构成持点。结果表明：玉香油占和胜泰1号的高产主要是因为颖花数和结实率的优势，而准两优527高产的获得主要是由于结实率和千粒重的优势。在此基础上．进一步采用Logistic方程拟合了上述4个品种的籽粒灌浆进程，分析相关参数后得知：各供试超级稻品种的粒重潜力存在差异，且弱势粒的充实均不如对照品种汕优63。此外。各供试超级稻品种的灌浆均表现出了异步性，但异步的程度并不一致。因此，在生产上应当根据各超级稻品种本身的特性来制定配套的栽培方法，进而使其产量潜力得以更加充分的发挥。

| Abstract: | In order to find out the reasons of yield difference between super hybrid rice and conventional rice,the yield components of the super hybrid rice(Zhunliangyou 527 and Shanyou 63) and conventional rice(Yuxiangyouzhan and Shengtai No.1) were compared in this paper.The results showed that the superiority in 1000-grain weight was the main reason for super hybrid rice to obtain higher yield.Furthermore,the grain filling courses of 4 tested cultivars were analyzed by Logistic equation,and the results were showed... |
