摘要
电导率的高低与田间出苗率有显著的直线相关关系,种子批的田间出苗率随电导率的下降而增高;而电导率与种子植株的单株产量呈曲线相关关系,低电导率的种子在单株产量上仍具有优势;电导率对单株产量的影响通过产量构成因素实现,除百粒重外,电导率与其它产量构成因素的相关系数均达显著或极显著的水平,其中与空杆率的关系最密切。
There existed linear correlation between field emergence rate and electric conductivity and presented curve Correlation between individual yield and electric conductivity, The grain yield per plant and its components such as row mumler per ear and seed number per row have negative correlation with electric conductivity, and presented positive correlation with sterile plant rate.
