The karyotypes of the three annuals,Microseris bigelovii, M. douglasii andM. pygmaea, consist of 2n = 18, small, submetacentric chromosomes. Length, centromere position, C-banding pattern, silver staining of NOR's, and the use of base specific fluorochromes, allow the identification of four of the nine chromosome pairs. The banding pattern ofM. bigelovii andM. pygmaea is identical, but intraspecific differences are found between strains ofM. douglasii. 相似文献
