Abstract:

The karyotype of representative species of eight genera in Magnoliaceae, including

Magnolia,Manglietia ,Michelia ,Paramichelia , Tsoongiodendron ,Parakmeria, Lirioden-

dron and Manglietiastrum, was studied. Their karyotype formulas are as follows: Magno-

lia coco 32m + 4sm + 2st(2SAT); Manglietia glauca 32m + 4sm + 2st(2SAT); Paramiche-

lia baillonii 34m (2SAT) + 2sm + 2st (2SAT); Tsoongiodendron odorum 32m + 6sm

(2SAT); Parakmeria omeiensis 56m + 16sm + 4st(2SAT); Liriodendron chinense 32m +

4sm(2SAT) + 2st(SAT); Manglietiastrum sinicum 28m + 4sm + 6st(6SAT); Michelia al-

ba 34m+ 4sm(2SAT). The karyotype evolution of Magnoliaceae is discussed.

Key words: Magnoliaceae, Karyotype analysis, Karyotype evolution
