Abstract研究了木兰科(Magaoliaceae)3个杂交组合的亲本和杂交后代的核型。结果表明,云南含笑(Michelia yunnanensis)、灰岩含笑(Michelia calcicola)及其杂交组合A的核型分别为2n=2x=38=36m+2sm、2n=2x=38=34m+4sm和2n=2x=38=26m+12sm;紫花含笑(Michelia crassipes)及其与云南含笑杂交组合C的核型分别为2n=2x=38=32m+6sm和2n=2x=38=24m+12sm+2st;山玉兰(Mognolia delavayi)、广玉兰(Mognolia grondiflora)及其杂交组合U的核型分别为2n=2x=38=28m+10sm、2n=6x=114=88m+lOsm+16st和2n=4x=76=57m+15sm+4st。杂交组合的核型与理论核型存在明显的差异,可能是在杂交组合的形成过程中,来自亲本的染色体发生了结构变异。
