摘要
对两种采自宁夏沙坡头的沙生植物骆驼刺和苦豆子进行了染色体观察。观察结果表明：骆驼刺的体细胞染色体数目为 2n = 16，其和型公式为 2n = 2x = 16 = 8sm + 8st。苦豆子的体细胞染色体数目为 2n = 36。
The chromosomes of A.sparsifolia and S.alopecuroides have been studied. The results show that the numbers of the xomatic chromosomes of A.sparsifolia is 2n = 16, and the karyotype formula is 2n =2x = 16 = 8st + 8sm, the number of the somatic chromosomes of S.alopecuroides is 2n = 36.
