摘 要 ：作者对重楼属（Paris）的几个种：球药隔重楼（P.fargesii) ，毛重楼（P.mairei)花叶重楼(P.marmorata),黑籽重楼（P.thibetica)，海南重楼（P.dunnianaa)，巴山重楼( P.bashanensis),以及多叶重搂（P.polyphylla)的两个变种狭叶重楼（var.stenophylla)华重搂（var.chinensis)的染色体核型进行了研究，发现种间及种内不同居群(population）间的核型都存在不同程度的差别。

Abstract:Karyotypes in eight of Paris, namely, P. fargesii, P. mairei, P. thibetica, P. dunniana, P. bashanensis, P. marmorata, P. polyphylla var. stenophylla and P. polyphylla var. chinensis, were studied. The karyotypes can be formulated as follows: P. fargesii K(2n) = 2x= 10 =6m+ 2t (SAT) + 2t+ 3bs; P. mairei K (2n) ==2x= 10=6m+ 4t+ 1bs; P. thibetica, K(2n) =2x= 10 =2m+ 4m (SAT) + 4t; P. dunniana K(2n) = 2x= 10= 6m+ 2t (SAT) + 2t3 P. bashanensis, K(2n) = 2x= 10=6m+ 4st; P. marmorata K(2n) = 2x== 10 = 6m + 4t3 P. polyphylla var. stenophylla K(2n) = 2x= 10 = 6rn+ 1st + 3t3 and P. polyphylla var. chinensis, K(2n) =2x= 10 =6m+ 4t.
