摘　　要：以2010年辽宁省盐碱地研究所试验点省区试中晚熟组部分水稻品种为试材,测定稻米品质及水稻群体光合速率,结果表明:水稻品种间稻米品质及群体光合速率均存在差异,齐穗后14 d左右时水稻群体光合速率与稻米的垩白粒率、垩白度呈显著或极显著正相关。The rice quality and rice canopy apparent photosynthetic rate were tested by using varieties which were mid-late varieties and come from Liaoning Saline or Alkaline Land Utilization and Research Institute. The results indicated that rice quality and photosynthetic rate of filling stage exist difference among different varieties, there were significant or extremely significant positive correlation among rice canopy apparent photosynthetic rate, chalk rate and chalkiness degree.

关 键 词：水稻 光合速率 稻米品质
