摘要
对分布于我国的木来木属CornusL .(广义 ) 4个主要类群的 5种植物进行了细胞学研究。结果表明 ,这 5种植物的染色体数目和核型分别为 :灯台树C .controversaHemsl.2n=2 0 =2m +8sm +1 0st;红瑞木C .albaL .2n =2 2 =8sm +1 2st+2t;毛木来C .walteriWanger.2n =2 2 =8sm +1 4st(0_2SAT) ;山茱萸C .officinalisSeib .etZucc .2n =1 8=8m +1 0sm (0_2SAT) ;四照花 (变种 )C .kousavar.chinensisOsborn 2n =2 2=2sm +6st (0_2SAT) +1
Five species of four main groups of Cornus L. (s.l.) from China were investigated cytologically. The chromosome numbers and karyotype formalas are as follows: C. controversa Hemsl. 2n=20=2m+8sm+10st; C. alba L. 2n=22=8sm+12st+2t; C. walteri Wanger. 2n=22=8sm+14st (0-2SAT); C. officinalis Seib. et Zucc. 2n=18=8m+10sm (0-2SAT); C. kousa var. chinensis Osborn 2n=22=2sm+6st (0-2SAT)+14t.
