| 摘 要： | 以海滨锦葵(Kosteletzkya virginica)胚轴为外植体, 在9种不同激素配比的培养基上进行愈伤组织诱导、继代培养、不定芽分化及生根培养, 确定了植株再生的最适培养条件: (1)愈伤组织诱导最适培养基为MS + IAA 1.0 mg.L-1 + KT 0.3 mg.L-1 + sucrose 30 g.L-1 + agar 8 g.L-1, 愈伤组织诱导率为93.94%; (2)不定芽诱导最适培养基为MS + IAA 0.1 mg.L-1 + ZT 0.5 mg.L-1 + sucrose 30 g.L-1 + agar 8 g.L-1, 不定芽诱导率为65.83%; (3)生根最适培养基为MS + sucrose 30 g.L-1 +agar 8 g.L-1, 生根率为96.67%。炼苗移栽后, 成活率可达85%。

| Abstract: | The embryo exes of Kosteletzkya virginica were used as explants for induction of callus, buds and roots on nine culture media with different hormone combinations. The best results were achieved on the following media: (1) 93.94% callus induction on MS medium supplemented with 1.0 mg.L-1 IAA, 0.3 mg.L-1 KT, 30 g.L-1 sucrose and 8 g.L-1 agar; (2) 65.83% shoot induction on MS medium supplemented with 0.1 mg.L-1 IAA, 0.5 mg.L-1 ZT, 30 g.L-1 sucrose and 8 g.L-1 agar; and (3) 96.67% rooting on MS medium containing 30 g.L-1 sucrose and 8 g.L-1 agar. The survival rate of the plantlets was 85% after being transplanted into soil. |
