摘要
为使杂交辣椒规模制种中获得最高效益 ,对海南、山西、江苏辣椒制种基地的 3种不同栽培模式不同阶段影响授粉效率的因素进行相关分析及通径分析 ,结果表明 ,三大基地影响授粉效率因素变化规律较为一致 ;种子千粒重在各阶段变化幅度较小 ,其主要由亲本特性决定 ;坐果率和日授粉花数受亲本特性和栽培条件的共同作用 。
Relative analysis and path analysis were made on the elements influencing pollination efficiency at different stages in Hainan,Shanxi and Jiangsu where pepper was cultured under different culture models.The results show that variation laws of factors influencing pollination efficiency in 3 bases are identical.Weight per 1 000 hybrid seeds vary little at different stages and they are decided by their parents characteristics.Fruit setting percentage and pollination flowers per day are coated on by parents characteristics and culture conditions,which influence pollination efficiency greatly.
