摘　　要：６个早籼品种的分期播种试验结果表明：（１）强势粒与弱势粒的稻米垩白度差异，有强势粒显著高于弱势粒、强势粒显著低于弱势粒和强势粒与弱势粒无显著差异３种类型。（２）相同的温度变化对强势粒和弱势粒垩白度的影响不同，强势粒到达垩白最小时的温度可能高于弱势粒。（３）垩白与粒重之间的关系相当复杂，并受到供试品种和实验条件的强烈影响。In this experiment,six indica rice varietes of different grain chalkiness were sown in the field and grown in three different seasons The results showed:(1)The chalkiness of superiorgrains might statistically be higher,lower than or equal to that of inferior grains;(2)The ef-fects of temperature change on the chalkiness of supperior grains were different from those onthe chalkiness of inferior grains.It seems that the grain- filling temperature for the superiorgrains to get minimum chalkiness was higher than that for the inferior grains.(3)the relationbetween chalkiness and grain weight seemed to be quite complex and was dependent on the va-rieties tested and the experiment conditions.
