| 摘 要： | 以中大粒品种郑引1号为试验材料,研究了不同粒重种子对幼苗长势及幼穗发育的影响.结果表明,大粒种子出苗迟,生长发育快,叶片分化持续时间短,幼苗长势壮;大粒种子的幼穗发育开始早,分化强度大,形成小穗数多.茎生叶分化总数不因粒重不同而发生变化.

| Abstract: | Zhengyin No.1, the mid big grain variety, is chosen as experiment material, effect of different grain weight seed on seedling and its young spike development are studied. Results show that the seedling is late, growth and development is quick, the time of leaf to divide is short and its seedling is strong for the big grain seed. Young spike development of the big grain seed starts early, the strength to divide young spike is big. In the end the big grain seed comes into being more spikelets. The total amount of the foliation in stalk to divide is not changed because of the different grain weight seeds. |
