摘    要:为获得龙牙百合高品质的鳞球种球,加快组培快繁进程,以龙牙百合小鳞芽为试材,通过组织培养的方法进行了鳞球增重及生根培养研究.结果表明,诱导龙牙百合小鳞芽生长发育成鳞球的最适培养基为MS+IAA1.0mg/L;龙牙百合鳞球增重的最佳培养基为MS+6-BA1.0mg/L+2,4-D0.5mg/L,培养基蔗糖质量分数影响鳞球的增重,适当提高蔗糖质量分数对鳞球的增重有促进作用,以5%效果最好;鳞球生根的最适培养基为1/2MS+IBA0.5mg/L.

关 键 词:龙牙百合  鳞球增重  生根

Abstract:Using buds in Lilium brownii var. viridulum as research material,by the way of tissue culture,we have drawn the following conclusions:The experiments showed that the medium MS supplemented with 1.0 mg/L IAA was fitting for inducing buds change to bulbs.The medium MS supplemented with 6-BA1.0 mg/L and 2,4-D 0.5 mg/L was fitting for putting on weight,and the density of bagasse affected putting on weight,using 5 percent bagasse will get better result.The medium 1/2MS supplemented with IBA 0.5 mg/L was perfect for growing roots.
Keywords:Lilium brownii var. viridulum  bulbs putting on weight  growing roots
