摘　　要：豫薯 8号茎叶生长快 ,结薯早 ,光合面积大 ,光合能力强 ,T/R进展合理 ,前期光合产物积累主要分配到地上部茎叶 ,中后期向地下部块根输送迅速增加 ,源库关系协调。其块根膨大有两个高峰期 ,分别为栽后的 50～ 70d和 90～ 1 1 0d。Vines of sweetpotatoes Yushu No.8 grew quickly;storage root expanded early,photosynthesis area and intensity was large, T/R ratio was rational. Its photosynthesis matter accumulation was distributed to vines mainly in early growth stage and moved to storage root speedily in middle and later stages. It had harmonious source-sink relationship and two storage root swelling peaks, at 50～70 days and 90～110 days after transplanting.
