摘　　要：为探讨酚类物质与百合鳞茎休眠的关系,研究了3种不同浓度下对羟基苯甲酸、阿魏酸、水杨酸和香豆素处理对鳞茎萌发的影响。结果表明：在100-500 mg/mL浓度范围内,中、低浓度的对羟基苯甲酸和水杨酸抑制了鳞茎萌发,随着浓度升高,鳞茎萌发率显著增加,顶芽在鳞茎内的萌动加快,鳞茎出苗日期提前。香豆素对百合鳞茎萌发有明显促进作用,500 mg/mL处理鳞茎发芽率最高,200 mg/mL处理的出苗一致性最好。阿魏酸与百合鳞茎休眠没有显著相关关系。For making clear the relationship between phenolics and dormancy in Lily bulb, the effects of 4-hydroxybenzoic acid, ferulic acid, salicylic acid and coumarin with different concentration on sprouting of bulb were studied. The results indicated that 4-hydroxybenzoic acid and salicylic acid under middle and lower concentration restrained the sprouting. Along with the increasing of concentration, the sprouting percentages, developing of bud in the bulb and plantlet emergence were improved significantly. Coumarin advanced the sprouting of bulb obviously, especially 500 rng/mL and 200 mg/mL was the best treatment for the sprouting percentage and plantlet emergence regularity, respectively. Ferulic acid was not related to the dormancy of bulb.
