摘要
通径系数分析结果,有效茎数对蔗茎产量的直接正效应大于株高和茎径;蔗汁蔗糖分对甘蔗蔗糖分的直接正效应大于其它品质性状,蔗汁旋光度、锤度、纯度和田间锤度对甘蔗蔗糖分具有较大的间接正效应;纤维分和还原糖分对甘蔗蔗糖分分别具有较大的直接和间接负效应;甘蔗蔗糖分对蔗糖产量的直接正效应略大于蔗茎产量。
Path coefficient analysis indicated that the positive direct effect of millable stalks on cane yield was bigger than those of plant height and stalk diameter.Sugar content in juice had a bigger positive direct effect against sugar in cane in all quality attributes;pol,brix,purity in juice and brix in cane possessed Stronger positive indirect effect against sugar in cane.Fibre content and reducing sugar percentage respectively had stronger direct and indirect negative effect against sugar content in cane.The positive direct effect of sugar content in cane on sugar yield was a little stronger than that of cane yield.
