| 摘 要： | 以粒重差异明显的个大穗型两系杂交水稻组合为材料,对粒重与光合特性的关系进行了初步研究.结果表明:供试组合整穗实粒平均千粒重与结实期顶部3片功能叶的"净光合速率/实粒"及"叶总面积/实粒"成正相关,实粒平均千粒重差异程度随结实期顶部3片功能叶的净光合速率和叶面积的变化而异.

| Abstract: | The hybrid rice combinations contrasting in grain weight were used as the materials to study the relationship between grain weight and net photosynthetic rate. The results showed that the weight averaged of the filled grains of a whole panicle was positively correlated with both net photosynthetic rate and leaf area of the uppermost three leaves per the filled grain at the grain-filling stage. The weight averaged over the filled grains charged of the net photosynthetic rate and leaf area of the upper three leaves at the grain-filling stage. |
