The lower solar radiation (437 and 377g cal/cm^2/day, respectively for the ripening stage in the first and second crop season, respectively) might be a main cause attributed. However the morphologically inferior light receiving system of the plant in the second crop might also be a factor attributable since IR 8, a variety with a better plant type, got a higher yield with a higher optimum LAI in the same crop season.
4第二期作登熟期间叶面净同化率之低落予料和该生育期间之平均日射量较低事实有关（第一、二期各为437及377g cal/cm^2/day），但从IR 8品种以更大叶面积指数获得更多收量一事可以予料第二期作水稻受光态势较劣亦是一个因素而将来由於品种之改良提高收量之希望很大。
