摘要
利用常规根尖压片法对大花萱草4个优良品种的染色体数目进行了鉴定,其中吉星(Hemerocallis‘Butter Curls’)2n=2x=22;金娃娃(Hemerocallis‘Stella de Oro’)2n=2x=22;奶油卷(Hemerocallis‘Betty Woods’)2n=2x=22;红运(Hemerocallis‘baltimore Oriole’)2n=3x=33。同时对其中的奶油卷进行了染色体核型分析,其核型公式为2n=2x=10m+6sm+4st+2T,属于Stebbins核型的2B型。
The chromosome number of fine variety of Hemerocallis hybrida hort. was identified by the conventional squashing method. The results showed as follows： Hernerocallis ＇Butter Curls＇ 2n=2x=22; Hemerocallis ＇Stella de Oro＇ 2n=2x=22; Hemerocallis ＇Betty Woods＇ 2n=2x=22; Hernerocallis ＇baltimove Oriole＇ 2n=3x=33.The karytotype of Hemerocallis ＇Betty Woods＇was analyzed. The karyotype formula is 2n=2x=10m＋6sm＋4st＋2T, belonging to 2B type of Stabbings karyotypic symmetry.
