| 摘 要： | 研究了不同地区的4种栽培蕌头(Allium chinensis G.Don)的染色体组型,结果表明:兰蕌的染色体组型为2n=4x=32=24m+8sm(SAT);桃源蕌2n=4x=32=28m(SAT)+4sm;利川蕌2n=4x=32=24m(SAT)+4sm+4st;丝蕌2n=3x=24=21m+3sm。通过分析比较4种蕌头的染色体组型,对蕌头的品种分类问题及蕌头常开花而不易结子的原因进行了探讨。

| Abstract: | The karyotype of four Chinese scallions (Allium chinensis G. Don) was studied. The results showed that the karyotype of blue scallion is 2n=4x=32=24m+8sm(SAT); Taoyuan scallion is 2n=4x=32=28m(SAT)+4sm; Lichuan scallion is 2n=4x=32=24m(SAT)+4sm+4st; and silk scallion is 2n=3x=24=21m+3sm. Meantime, according to the karyotype analysis, Classification of chinese scallions and problem of its blooming but rare seeding are discussed. |
