摘　　要：研究了不同叶龄光周期诱导对圆果种黄麻营养期长短、产量和产量性状的影响 ,结果表明 :营养期长短受 7叶龄以上光周期诱导的影响是随叶龄的增大呈显著或极显著负相关 ;7叶龄前的与 7叶龄后的处理 ,其产量和产量性状有明显差异 ;在 7叶龄之后 。Responses of different leaf number of White jute to photo-period were studied on the duration of vegetative growth,yield and yield components.The results showed that the duration of vegetative growth was affected by the photoperiod induction when the plants were over 7 leaf number,which was significant or highly significant negative correlation with the leaf number increased.There was an obvious difference in yield and yield components from 7 leaf number,and the yield coponents were increased with the leaf number added.
