摘要:

本文对云南西北部百合科6属15种的染色体和核型进行了报道。 (1)Clintonia udensis Trautv.et Mey间期核属于浓密分散型,前期染色体属于渐变型,分裂中期体细胞染色体2n=14=8m+4sm+2st(2SAT),核型不对称性属于2A型;(2)鹿药属四个种间期核属于复杂中央微粒型,前期染色体属于中间型,分裂中期体细胞染色体分别为Smilacina henryi(Baker)Wang et Tang,2n=36=12m+16sm+6st+2t(2SAT),  核型不对称性属于2C型;Smilacina fusca Wall., 2n=36=14m(2SAT)+12sm+10st(2SAT),  核型不对称性属于2B型;  Smilacina tatsienensis(Franch.)Wang et Tang,  2n=36=22m+2sm+2st(2SAT),  核型不对称性属于2C型;Smilacina atropurpurea(Franch.)Wang et Tang,2n=36=18m+6sm(2SAT)+12st,核型不对称性属于2C型;(3)黄精属四个种的间期核属于复杂中央微粒型,前期染色体属于中间型,分裂中期体细胞染色体分别为Polygonatum kingianum Coll.et Hesml.,2n=30=12m(2SAT)
+6sm+lst+2t,  核型不对称性属于2C型;  Polygonatum cirrhifolium(Wall.)  Royal,2n=30=10m+4sm+12st+4t,  3C型;  Polygonatum  curvistylum  Hua,  2n=78=24m(2SAT)+14sm(6SAT)+40st,  核型不对称性属于3C  型;  Polygonatum  cathcartii  Baker,2n=32=12m+6sm+10st+2t+2bs,核型不对称性属于2C型;(4)百合属,假百合属,豹子花属三个属的间期核和前期染色体形态相似,都属于复杂中央微粒型,前期染色体属于中间型,分裂中期体
细胞染色体分别为Lilium  henricii Franch,2n=24=2m(2SAT)+2sm+10st+10t,核型不对称性属于3A型;Lilium bakerianum Coll.et  Hesml.var.  rubrum  Stearn,    2n=24=4m  (2SAT)+10st+10t(2SAT),核型不对称性属于3A型;Nomocharis bilouensis Liang 2n=24=2m(2SAT)+2sm+12st+8t,核型不对称性属于3A型;Nomocharis pardanthina Franch.,2n=24=4m(2SAT)+12st (2SAT)+8t,核型不对称性属于3A型;Nomocharis sauluensis Balf, f.,2n=24=4m(2SAT)+10st(2SAT)+10t,核型不对称性属于3B型;Notholirion campanulatum Cotton et Stearn
2n=24=2m(2SAT)+2sm+14st(2SAT)+6t,核型不对称性属于3A型。

Abstract:

 Fifteen  species  in  six  genera  of  the  family  Liliaceae  were karyomorphologically studied. They share the complex chromocenter type of the resting nuclei and the interstitial type of the prophase chromosomes in somatic cells except that Clintonia udensis Trautv. et Mey is of the densely diffuse type and gradient type respectively. Their karyotype formulas are listed as follows: Clintonia udensis Trautv. et Mey, 2n= 14=8m+4sm+2st (2SAT), belongs to 2A type;   Smilacina henryi (Baker) Wang et Tang, 2n=36=12m+16sm+6st+2t (2SAT),   2C   type;    Smilacina   fusca    Wall.,   2n = 36= 14m (2SAT)
+ 12sm+ 10st(2SAT), 2B type;  Smilacinata tsienensis (Franch.) Wang et Tang, 2n= 36=22m +2sm+ 2st(2SAT),  2C  type;   Smilacina  atropurpurea ( Franch.) Wang  et  Tang,  2n=36=18m+6sm(2SAT) +12st,  2C  type:  Polygonatum kingianum Coll,  et  Hesml.,  2n=30= 12m(2SAT) +6sm+ lst+2t,  2C  type;  Polygonatum cirrhifolium (Wall.) Royal, 2n=30= 10m+4sm+ 12st+4t, 3C type;  Polygonatum curvistylum Hua, 2n=78=24m (2SAT)+ 14sm (6SAT)+40st, 3C type;  Polygonatum cathcartii Baker, 2n = 32 = 12m + 6sm + 10st+ 2t + 2Bs, 2C type;  Lilium henricii Franch., 2n = 24 = 2m(2SAT) + 2sm + 10st+ 10t, 3A type;  Lilium bakerianum  Coll. et  Hesml.   var.   rubrum  Stearn,   2n=24=4m ( 2SAT) +10st+ 10t (2SAT), 3A type;  Nomocharis bilouensis Liang, 2n= 24= 2m (2SAT) +2sm+ 12st+ 8t, 3A type;  Nomocharis pardanthina Franch., 2n= 24=4m (2SAT)
+12st (2SAT)+ 8t, 3A type;  Nomocharis sauluensis Balf. f., 2n=24=4m(2SAT)  +10st (2SAT) + 10t,  3B  type;   Notholirion  campanulatum  Cotton  et Stearn 2n = 24 = 2m (2SAT) + 2sm + 14st(2SAT ) + 6t, 3A type.
