摘要: 利用扫描电镜对安徽省栽培的莴苣Lactuca sativa及其变种的果实进行观察,结果发现涡阳县义门镇特产的苔菜既不同于莴笋L.sativa var.angustata,也不同于莴苣,应将其建立在莴苣种下作为新变种苔菜L.sativa L.var.yemensis X.S.Shen et R.L.Lu var.nov.更为合适。

Abstract: The scanning electron microscope observation was given for the achenes of Lactuca sativa, L.sativa var.angustata, L.sativa var.romana and L.sativa L.var.yemensis X.S.Shen et R.L.Lu which was reported as a new variety in this paper.The stem and leaves of the new variety are covered with white wax powder.Its vascular tissue is not developed very well.The stem is even from base to top.The structure of the leaf is isobilateral.The obovate-elliptic achene possesses sparsely 8-12 rhaphes, and part of them are disappear in the top of the achene.
