Chromosome Number of Isoetes sinensis Palmer, A Rare and Endangered Pteridophyta Plant

    摘要
  • Abstract: Aresearch of interphase nuclei and chromosome number of Isoetes sinensis Palmer was made in the article. The chromosome number of Isoetes sinensis Palmer was 2n=4x=44. The interphase nuclei were categorized to be simple chromocenter type. The metaphase chromosomes were about 5 μm in length.In addition,the mitotic process was observed. These results could supply the cytological evidence for the exploration of the biosystematics and endangerment mechanism of this species.
