摘要
报道了三种植物的染色体数目及核型.紫花地丁( Viola yedoensis Makino) 染色体数目为2 n = 24 ,核型公式 K(2 n) = 24 = 24 m ,核型“1 A”型;酸模叶蓼( Polygonum laphathifoliu m L·) 染色体数目为2 n = 22 ,核型公式 K(2 n) = 22 = 12 m + 10 sm ,核型“2 A”型;射干( Belamcanda chinensis ( L.) D C) .染色体数目为2 n = 32 ,核型公式 K(2 n) = 32 = 16 m + 2 m(sat) + 6 sm + 4 sm(sat) + 4st,核型“2 A”型.
This paper reports the results of some karyotype studies of 3 species of plants from Shandong.The results showed:the chromosome number of Viola yedoensis Makino is 2n =24,its karyotype formula is K(2n )=24=24m,belonging to “1A”of Stebbins;the chromosome number of Polygonum laphathifolium L.is 2 n =22,its Karyotype formula is K(2n) =22=12m+10sm,belonging to “2A”of Stebbins;the chromosome number of Belamcanda chinensis (L )DC.is 2 n =32,its karyotype formula is K(2n) =32=16m+2m(sat)+6sm+4sm(sat)+4st,belonging to“2A”of Stebbins.
