Abstract: Super hybrid rice Liangyoupeijiu and Zhongyou 6 were used to analyze the relationship between specific leaf weight and photosynthetic rate at panicle initiation stage under different transplanting densities. Results showed that there was significant difference in the specific leaf weight and photosynthetic rate under various densities. The linear and positive relationship between the specific leaf weight and photosynthetic rate was observed from the same material.

Key words: specific leaf weight, photosynthetic rate, panicle initiation stage, super hybrid rice

摘要: 以超级杂交稻两优培九和中优6号作为研究材料, 研究了不同密度处理叶片比叶重和光合速率的关系,结果表明叶片比叶重和光合速率不同密度之间有明显差异,相同品种叶片的比叶重与光合速率呈线性正相关。
