Abstract
With the stem segments as explants of superior clone Lonicera japonica Thunb.of Cangyuan 1#,the rapid propagation techniques in vitro were developed in this paper.The results showed that the optimum medium of shoot induction was MS +BA 0.5 mg/L+ IBA 0.5 mg/L,and the middle stem section was the suitable material for the explants;the appropriate proliferation medium was MS + BA 0.1~0.5 mg/L + NAA 0.1~0.3,the multiplication coefficient can reach 6.5;and the effective medium for rooting was MS+IBA 2.0 mg/L,the rooting rate can reach 93%.
