摘　　要：新疆有着丰富的旱生植物、盐生植物资源,其中有许多具有多型性种子的植物,猪毛菜属(Salsola L.)植物就是其中之一。中国有猪毛菜属植物37种、1个变种,主要分布于新疆(33种)地区。本文对新疆地区的粗枝猪毛菜(S.subcrassa M.Pop.)、东方猪毛菜(S.orientalis S.G.Gmel.)、短柱猪毛菜(S.lanata Pall.)、钝叶猪毛菜(S.heptapotamicalljin)、褐翅猪毛菜(S.korshinskyi Drob.)、浆果猪毛菜(S.foliosa(L.)Schrad.)、木本猪毛菜(S.arbuscula Pall.)、钠猪毛菜(S.nitraria Pall.)、天山猪毛菜(S.junatovii Botsch.)和小药猪毛菜(S.micranthera Botsch.)的种子进行观测。结果表明:这10种猪毛菜属植物的种子都具有种子多型性现象,每一种猪毛菜都有2种不同类型的种子,在颜色、直径、质量、形状等性状上表现不同。本文所研究的具有多型性种子的猪毛菜种类约占新疆猪毛菜属植物种类的30%、中国的26%。Xinjiang is rich in xerophyte and halophyte resources, many of which have seed pol- ymorphism phenomenon, and Salsola L. is one of them. There are 37species and one variety of Salsola L. in China, mainly distributed in Xingjiang（33 species）. Investigations on the seeds of the following species of S. subcrassa M. Pop. , S. orientalis S. G. Gruel. , S. lanata Pall. , S. heptapotamica lljin, S. korshinskyi Drob. , S. arbuscula Pall. , S. foliosa（L. ） Schrad. , S. arbuscula Pall. , S. nitraria Pall. , S. junatovii Botsch. and S. micranthera Botsch. in Xinjiang showed that seed polymorphism phenomenon was observed in all this 10 species of Salsola L. , and each had two different types of seeds and showed different in color, shape, diameter, quality and so on. The S. collina Pall. species having seed polymerphism phenomenon studied in this paper occupy about 30% of all the species of Salsola L. in Xin- jiang and about 26% of all the species of Salsola L. in China.
