Abstract

Abstract:

The present work reports the chromosome numbers of 30 species of 7 ge-

nera of Magnoliaceae in China. The chromosome numbers of Liridendron chinense, Ma-

gnolia officinalis, M. liliflora, Michelia rigo and M. champaca are consistent with those

previously reported Magnolia denudata was reported 2n=114, but our result shows 2n=

76; M. grandiflora was reported 2n=112, 114, but here 2n=114. Chromosome numbers of

the other 23 species are reported for the first time. Vouchers for experimental materi-

als have been preserved in Herbarium of the Department of Biology, Nankai University,

Tianjin.

Key words: Chromosome number, Magnoliaceae.
