盐穗木的染色体数目与核型分析

摘要: 盐穗木（Halostachys caspica）是新疆荒漠盐碱地常见的盐生植物。本研究以盐穗木萌发种子的根尖为材料，采用常规压片法对根尖细胞有丝分裂中期染色体进行数目统计及核型分析。结果表明，盐穗木体细胞染色体数目为2x=18条，染色体核型模式为2n=2x=18m，4号染色体含两个随体（SAT），属于1A染色体核型。

Abstract: Halostachys caspica is a dominant halophyte, which is widely distributed in Xinjiang desert region. The chromosome number and karyotype of H.caspica were analyzed by using cytological observation on the roottip. The results showed that the chromosome number of H.caspica is 18 with karyotype formula being 2n=2x=18m. There are two satellite chromosomes in the forth chromosome. The karyotype of H.caspica belongses to 1A type.
