摘　　要：通过对全年 8次分期播种的 5个较具代表性的早籼稻品种的各项稻米品质与结实期日均温的相关分析 ,结果表明 :稻米品质与结实期日均温有一定的负相关性 ,它们之间存在的很可能是某种另外较复杂的关系。不同品种及不同性状对温度的反应不一样 ,品质较好的品种受结实期日均温的影响要小于品质较差的品种 ,糙米率、粒长、G .T等 3项米质性状与日均温的相关性密切。The result of correlation analysis for quality of 5 representative early indica rice which were planted for 8 times during a whole year and daily average temperature in ripening period shown as follows: There are negative correlation coefficient somehow between quality of rice and daily average temperature in ripening period. May be more compulsive coefficient exist. Different varieties or characters answer for change of temperature independently, varieties of better quality have a little transformation with the change of temperature than varieties of worse quality. Brown rice yield, length of grain and G.T have notable correlation coefficient with daily temperature in ripening period.
