摘　　要：对百合鳞片各部位在不同贮藏温度下的游离氨基酸含量和组分进行了定量分析。结果表明:百合鳞片各部位的游离氨基酸含量总体呈先上升后下降的趋势,冷藏的第4周游离氨基酸含量发生显著变化。游离氨基酸含量以内部鳞片>中部鳞片>外部鳞片。各部位鳞片以精氨酸的含量最高、变化最大,其次是谷氨酸、苏氨酸等,精氨酸、谷氨酸等谷氨酸族在百合鳞茎休眠解除过程中起重要作用。The study analysised quantitatively the content and composition of free amino acids in different parts of lily scale in a different store temperature. The results showed that contents of free amino acids in different parts of lily scale increased at the beginning, and then decreased, it changed evidently at the 4^th week of storage. Free amino acids in lily scale existed mostly inner scales, Arginine was the most amino acid and it changed greatly. Amino acids belong to glutamic acid family such as arginine and glutamine acted important effect during dormancy release of lily bulb.
