摘  要：
对头季稻收获时单本株的农艺性状与其再生力的强弱进行了相关性研究。结果表明 :头季稻收获时 ,单本株的每穗实粒数、结实率与再生芽数、再生率存在显著相关性 ,其他农艺性状均不存在显著相关 ;头季稻收获时 ,单本株头季稻的每穗实粒数、结实率与再生芽、再生率达极显著正相关 ,其中以幂回归相关为最大。表 2 ,参 14。

摘  要：
The relationship between agronomic traits per single plant during the harvest of main crop and their ratooning ability in hybrid mid rice was studied. The results are the followings:1.During the harvest of the main crop, the filled grains per panicle or fertility per single plant was significantly correlated with their ratooning ability in hybrid mid rice, but the others weren't interrelated.2.During the harvest of the main crop, highly significant positive correlations between the filled grains per panicle or fertility per single plant and their ratooning ability in hybrid mid rice was observed, optimum significant positive correlation was the power curvilinear regression.
