摘要
以 15个杂交中稻品种为材料 ,研究了发根力及根系活力与地上部性状的关系。结果表明 ,杂交中稻品种间发根力与有效穗、产量呈显著或极显著正相关 ,与着粒数呈极显著负相关 ;根系活力与结实率和产量呈极显著正相关。分蘖力强。
Fifteen hybrid mid season rice combinations were used to study the relationship between root growth ability and root flux activity and plant characteristics over ground There was significantly positive relationship between root growth ability and productive panicles,grain weight;and there were significantly negative relationship between root growth ability and grains per panicle Significantly positive relationship between root flux activity and seed setting rate,grain weight were observed Stronger tillering ability and higher seed setting rate might be used as an indirect index of good root growth ability and root flux activity of hybrid mid season rice
