| 摘 要： | 本文对我国原始木本被子植物木兰科中的木兰属Magnolia、木莲属Manglietia、含笑属Michelia、
合果木属Paramichelia、观光木属Tsoongioderdron、拟单性木兰属Parakmeria、鹅掌楸属Liriodendron、
华盖木属Manglietiastrum 8属代表种的核型进行了研究。各属代表种的核型公式如下:夜合Magnolia
coco 32m+4sm+2st(2SAT)；灰木莲Manglieatia glauca 32m+4sm+2st(2SAT)；合果木Paramichelia
baillonii 34m(2SAT)+2sm+2st(2SAT)；观光木Tsoongiodendron odorum 32m+6sn(2SAT)；拟单性木
兰Parakmeria omeiensis 56m+16sm+4st(2SAT)；鹅掌楸Liriodendron chinense 32+4sm(2SAT)+2st
(2SAT)；华盖木Manglietiastrum sinicum 28m+4sm+6st(6SAT)；白兰 Michelia alba 34m+4sm(2SAT)。作者对木兰科核型进化问题进行了讨论。

| 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. |
