Analysis of DNA C-value and Ploidy of Five Species in Magnoliaceae

doi:10.7525/j.issn.1673-5102.2016.06.008

Abstract

Abstract: In this study, the C-value and ploidy of five species in Magnoliaceae was estimated by flow cytometry using Magnolia liliiflora as the reference. The results showed that the two species of Michelia are diploid, Magnolia grandiflora is hexaploid, and M.soulangeana is tetraploid. The C-Values of five species are different from each other. The C-value of M.grandiflora is the largest among the five species investigated, while the C-value of Liriodendron chinense×tulipifera is the smallest. The sizes of C-values of the five species are small to medium level.

Key words: flow cytometry, C-value, ploidy, Magnoliaceae
