非洲堇无根苗的试管内外生根研究

Research on Rooting of Saintpaulia ionantha in Vitro and in Vivo

以非洲堇的无根苗为试材,研究了其试管内和试管外的生根情况。结果表明,试管内生根以1/2 MS+0.20 mg/L NAA处理的生根情况最好,生根率为100%,平均生根数量35条,平均根长16.4 mm;试管外的生根率为98%,平均根长为15～20 mm,平均生根27条。

Taking rootless seedlings of Saintpaulia ionantha as materials, the rooting of Saintpaulia ionantha in vitro and in vivo was researched. The results indicated that the rooting of Saintpaulia ionantha in vitro was best when treated with 1/2 MS＋0.2 mg/L NAA.In this eonditon, the rate of rooting was 100 %, the average number of roots was 35, and the average length was 16.4 mm. while the rate of rooting in vivo was 98 %, the average length of roots was 15-20 mm, and the average number of roots was 27.
