【摘要】 1999年和2002年在田间条件下,对水稻群体光合速率及稻米碾磨和外观品质进行了研究。结果表明,不同水稻品种群体光合速率和稻米品质各指标存在差异,齐穗后15天左右的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,与精米率呈显著负相关。更多还原

【Abstract】 The canopy apparent photosynthetic rate (CAP) and grain quality of rice were investigated in the field experiments from 1999 to 2002.The results indicate that the CAP and grain quality are different among rice varieties. There is significant or highly significant positive correlation between the CAP of 15 days after heading and the chalky rice percentage/chalkiness; and there is significant negative correlation between the CAP of 15 days after heading and the white rice yields from paddy.更多还原
