摘要/Abstract

摘要： 新疆是我国沙拐枣属植物种类分布最多的省份, 有19 种, 约占总种数的82 . 6% , 其中刺果组中新疆特有种就有5 个。利用体视显微镜观察了新疆沙拐枣属刺果组野生的11 种植物的种子形态, 并编排分种检索表。结果表明: 该组植物的种子可分为3 大类: (1) 瘦果每肋上长一行刺; (2) 瘦果每肋上长二行刺; (3) 瘦果每肋上长三行刺。瘦果肋上刺毛的列数、交织和软硬程度显示出显著的差别, 可以作为沙拐枣属刺果组植物种间分类的依据。

关键词: 沙拐枣属刺果组, 种子形态, 分类学

Abstract: Species of Calligonum are xerophytes growing extensively in sand deserts and Gobi Deserts in China . Xinjiang is an area where the most species ( as many as 19 species) of Calligonum grow in China, and these species occupy 82.6% of the total species in China, in which 5 species are endemic to Xinjiang. In this study, the seed morphology of 11 species of Calligonum sect.Eucalligonum growing in Xinjiang is observed using a stereomicroscope, and a key to the species is provided. The results show that the species can be divided into three groups in terms of their seeds morphology: (1) species with one row of bristles along each rib of achene; (2) species with two rows of bristles along each rib of achene ; and (3) species with three rows of bristles along each rib of achene are significantly different , and these properties can be regarded as the taxonomic bases among the species of the sect. Eucalligonum.

Key words: Calligonum sect. Eucalligonum
