Abstract

Chromosome numbers and other karyological data for ten Stemona species and for Stichoneuron caudatum are presented, including first reports for Stemona burkillii, S. involuta, S. mairei and S. phyllantha. All investigated taxa of Stemona exhibit n = x =7 (2n =14) chromosomes. For Stichoneuron caudatum an earlier count revealing 2n =18 is confirmed. The observed chromosome lengths range between 0.9 and 6.9 μm (largest chromosome in Stichoneuron caudatum). Additionally, the genome sizes of seven Stemona species and of Stichoneuron caudatum are reported. The obtained results are compared with literature data and discussed.

茎科植物新染色体计数及其他核生物学资料

本文介绍了10种Stemona和Stichoneuron caudatum的染色体数目和其他核生物学资料，包括首次报道的burkillii、s.a involuta、s.m aei和s.p aylantha。所有被调查的Stemona类群都有n = x =7 (2n =14)条染色体。对于尾状下丘脑，较早的计数显示2n =18得到证实。所观察到的染色体长度在0.9 ~ 6.9 μm之间(尾状体最大的染色体)。此外，还报道了7种茎草属植物和尾尾刺神经元的基因组大小。所得结果与文献数据进行了比较并进行了讨论。
