獐牙菜属5种植物的核型研究(英文)
A karyomorphological study on 5 species of Swertia (Gentianaceae)
【摘要】 首次报道了中国 5 种獐牙菜属植物的染色体数目和核型。它们染色体中期核型和相对长度组分分别是:四数獐牙菜为 2n= 14= 4m + 8sm + 2st= 2 L+ 6 M 2 + 4 M 1+ 2 S;华北獐牙菜 2n = 28= 12m + 14sm + 2st= 6 L+ 8 M 2 + 8 M 1 + 6 S;二叶獐牙菜为 2n = 28= 14m + 4sm +10st= 2 L+ 14 M 2+ 10 M 1 + 2 S;抱茎獐牙菜为 2n= 20= 6m + 12sm + 2st= 8 M 2+ 12 M 1 ;浙江獐牙菜为 2n= 20= 8m + 4sm + 8st= 8 M 2+ 12 M 1。
【Abstract】 he present paper reports the karyomorphological data of 5 species of Swertia .The karyotype formulae are as follows: S.teraptera 2n=14=4m+8sm+2st=2L+6M 2+4M 1+2S; S.wolfangiana 2n=28=12m+14sm+2st=6L+8M 2+8M 1+6S; S.bifolia 2n=28=14m+4sm+10st=2L+14M 2+10M 1+2S; S.franchetiana 2n=20=6m+12sm+2st=8M 2+12M 1; S.hickinii 2n=20=8m+4sm+8st=8M 2+12M 1.The chromosome numbers and karyotypes of all species are reported for the first time.
