【摘要】 以小蔓长春花嫩枝的茎段和茎尖为外植体,经90天的增殖培养试验表明,最适宜的增殖培养基为MS+6-BA 0.8~1.2 mg.L-1+IBA 0.2~0.4 mg.L-1,诱导生根的最佳培养基为1/2MS+IBA0.1~0.5 mg.L-1,生根率为96.3%~100%。瓶外生根试验结果表明,用1 000~1 200 mg.L-1IBA蘸根,生根率达81%。更多还原

【Abstract】 Tissue culture was made with the stem-segments and shoot tips of Vinca minor as explants.By the multiplication culture of 90 days,the result showed that the optimum medium was MS + 6-BA 0.8～1.2 mg·L^-1+ IBA 0.2 ～ 0.4 mg·L^-1.The best rooting medium was 1/2 MS+ IBA 0.1～0.5 mg·L^-1.The rooting rate was 96.3%～100%.The rooting rate of Vinca minor tissue cultured shoots by treating with 1?000～1?200 mg·L^-1 IBA ex virto was 81%.更多还原
