| 摘 要： | 以块根着色程度不同的2个紫心甘薯品系‘A3’和‘山川紫’为试材,以白心甘薯‘禺北白’为对照,对其不同器官(叶、茎和块根)的花青素含量和苯丙氨酸解氨酶(PAL)的活性进行了测定,对它们之间的变化趋势进行了相关性分析并建立了回归模型.结果表明:不论是不同品系的整株水平,还是同一品系的不同器官,着色程度深的部位,花青素的含量较高,PAL活性也较高.相关性分析以及回归模型显示,花青素含量与PAL活性之间呈极显著的线性正相关.说明PAL是紫心甘薯花青素合成的关键酶.

| Abstract: | The contents of anthocyanin and the enzyme activities of phenylalanine ammonialyase(PAL) in different organs of three strains of sweet potato Ipomoea batatas(L.) Lam.],including two purple-fleshed strains(A3 and Yamakawamurasaki) and one white-fleshed strain(Yubeibai) were determined.The relationship between anthocyanin content and PAL activity was investigated by correlation analysis,and a linear regression model was established.The results indicated that the activity of PAL was significantly and positive... |
