野百合试管鳞茎诱导与增殖的研究（英文）

With different parts of bulb scale as explants,the proliferation method of Guizhou Lilium brownii were studied with 3% sodium hypochlorite and MS medium with different concentrations of hormones.The results show that it is feasible to disinfect the bulbs of Lilium brownii with 3% sodium hypochlorite,moreover,the sodium hypochlorite is very cheap and harmless to researchers,experimental materials and environment.MS+NAA 0.3 mg/L+6-BA 1.5 mg/L is optimum for the induction of bulbs and,the basal part of Lilium brownie is the optimum explants.After culture for 25 d on the same medium,the tube bulbs could be obtained with the characteristics of high propagation coefficient,strong and new roots.The survival rate is over 90% for transplantation of tube bulbs with diameter between 1-2 cm.The method developed in the present study can proliferate abundant Lilium brownii seedling in short time.
