| 摘 要： | 以Ⅱ优107(大穗)和汕优63(中穗)为试验材料,研究了2个品种灌浆结实期非结构性碳水化合物运转特征.结果表明,灌浆前期Ⅱ优107比汕优63具有较强的光合物质生产能力,齐穗期汕优63叶鞘和茎秆非结构性碳水化合物含量均高于Ⅱ优107.在物质主要输出期(齐穗后10 d内)和齐穗至成熟期间,非结构性碳水化合物输出量汕优63除倒1鞘略低于Ⅱ优107外,倒2、倒3鞘均高于Ⅱ优107,汕优63茎秆输出量要远高于Ⅱ优107.

| Abstract: | The field experiment was conducted in 2006 to determine the translocation of non-structural carbohydrates(NSC)from the stem to the grains of two indica rice cultivars with contrasting panicle traits,i.e.Eryou 107 with large panicle and Shanyou 63 with medium panicle.The results showed that during the early filling stage the photosynthetic productivity of Eryou 107 was higher than that of Shanyou 63,and that during the full heading stage,the content of NSC in the sheath and stem of Shanyou 63 was higher than... |
