A Karyological Study of Six Species of Cleisostoma from Hainan
海南隔距兰属植物6个种的核型分析

采用压片法对海南产隔距兰属植物6个种,即:大序隔距兰Cleisostoma paniculatum (ker-Gawl.) Garay、短序隔距兰C.striatum (Rchb.f.) Garay、短茎隔距兰C.parishii (Hook.f.) Garay、金塔隔距兰C.filiforme (Lindl.) Garay、尖喙隔距兰C.rostratum (Lodd.) Seidenf.、红花隔距兰C.williamsonii (Rchb.f.) Garay的染色体数目和核型进行了研究.结果如下:大序隔距兰2n=2x=38=36m+2sm;短序隔距兰2n=2x=38=2M+36m;短茎隔距兰2n=2x=38=2M+34m+2sm;金塔隔距兰2n=2x=38=38m;尖喙隔距兰2n=2x=38=36m+2sm;红花隔距兰2n=2x=38=34m+4sm(2SAT).主要由正中部着丝点区染色体组成.除尖喙隔距兰核型分类为1A型外,其他的都为1B型.
