伞形科植物染色体数目报告 总被引:3,自引:0,他引:3
In the present paper, chromosome numbers are reported for 33 species
and varieties of Chinese Umbelliferae which belong to 17 genera in the subfamily Api-
oideae. Chromosome number of each species is shown in Table I. Eighteen countings
are newly reported. Chromatin bridges and fragments were observed at anaphase I in
some materials. It is suggested that the fertility reduction in some species is due to
the chromosome aberrations. 相似文献
