摘要
本试验通过对零式分枝和混生类型的长绒棉品种产量性状的调查对比分析 ,发现混生类型品种的现蕾总量多于零式分枝品种 ,但二者成铃总数差异不明显。混生类型品种的单铃重明显高于零式分枝品种 ,平均增加 0 .14g ,子指、衣指均高于零式分枝品种。
Non fruit branch and intergrown fruit branch are two usual plant types of Gossypium Barbadense L. The trial shows that the square number of intergrown fruit branch varieties is more than that of non fruit branch varieties.But since the abscission rate of limited fruit branch is higher, the difference of boll number between the two plant types is not so significant. The weight of single boll in intergrown fruit branch varieties is significantly higher than that of non fruit branch varieties. The average increse weight is 0.14 g. And both seed index and lint index of intergrown varieties are higher than that of non fruit branch varieties. Therefore, the varieties with intergrown fruit branch have significant yield dominance.
