CYTOLOGICAL STUDIES ON SOME PLANTS OF WOODY FLORA IN HUANGSHAN,ANHUI PROVINCE

  • 摘要: 报道了黄山地区18种木本植物的染色体数,分属于15个科中的18个属,其中14种和2个属为首次报道;同时对Aphananthe,Fortunearia,Loropetalum,Holboellia,Platycarya属的染色体数及其在分类上的意义作了简单讨论。

     

    Abstract: chromosome numbers of 18 taxa belonging to 18 genera of 14 families in Huangshan are reported in this paper,the 14 taxa and 2 genera among them are reported for the first time.The cytological results revealed the chromosome number of Aphanan the aspera 2n=28,which is different from that of Oginuma reported in 1990 Platycarya strobilacea,the cytological results revealed 2n=22,is the only genus having the diploid in the Juglandaceae as reported so far.This shows that the genus Platycarya is isolated from the other groups of the family.The chromosome number of Holboellia coriacea is 2n=32.There are three forms of chromosome number,2n=28,30, 32 in the Lardizabalaceae,the genera having 2n=28 are native to south America,the genera having the other two forms of chromosome number are native to Eastern Asia.Author considers that Decaisnea is isolated from the other genera in Lardizabalaceae.
