酚类物质对百合鳞片扦插繁殖的影响

Effects of Phenolic Compounds on Scale Cutting Propagation in Lily

为进一步完善百合鳞片繁殖技术,以兰州百合及东方百合‘Sorbonne’为材料,研究了酚类物质对百合鳞片扦插繁殖的影响。结果表明,酚类物质的种类对兰州百合鳞片繁殖小鳞茎大小及生根量的影响大于处理浓度和时间,其中对羟基苯甲酸处理可促进小鳞茎膨大。处理时间对小鳞茎的繁殖系数及平均级数的影响效力较大,其中处理8h有利于提高小鳞茎的数量。进一步研究发现,100mg/L对羟基苯甲酸浸泡鳞片8h更有利于兰州百合和‘Sorbonne’小鳞茎膨大和增重,为提高小鳞茎质量的最佳处理。50mg/L水杨酸处理8h也可提高小鳞茎质量。

In order to further improve the techniques of scale propagation in Lilium,the effects of phenolic compounds on Lilium davidii var.unicolor and Lilium Oriental hybrid ＇ Sorbonne ＇ were studied for scales cutting propagation.The results showed that the effect of kind of phenolic compounds on the size of bulblets propagated by Lilium davidii var.unicolor as well as the number of roots was higher than concentrations and duration of treatments,in which 4-Hydroxybenzoic acid treatments could enlarge the bulblets.The effects of treatment duration on propagation coefficient and average grade was larger,in which disposed for eight hours was propitious to promote the number of bulblets.It was found that the bulblets both propagated by Lilium davidii var.unicolor and ＇ Sorbonne ＇ were much bigger and heavier when the scales was put in 100 mg/L 4-Hydroxybenzoic acid for eight hours in the further study,which was the best treatment for promote the quality of bulblets.The treatment of 50 mg/L salicylic acid disposed for eight hours could also promote the quality of bulblets.
