摘要
研究了驱蚊香草不同外植体的多酚氧化酶(PPO)活性,比较了单一抑制剂对驱蚊香草褐变控制的效果,采用正交试验,确定复合抑制剂在驱蚊香草褐变控制中的最佳组合。结果表明:驱蚊香草幼嫩芽的PPO活性最高,幼嫩叶片的PPO活性最低;单一抑制剂对驱蚊香草褐变抑制效果为:聚乙烯基吡咯烷酮(PVP)>抗坏血酸>柠檬酸>活性炭(AC),复合抑制剂对驱蚊香草的褐变最佳抑制效果为:抗坏血酸0.2%、PVP0.4%、柠檬酸0.5%。
In these experiment,the activity of polyphenol oxidase（PPO） in differentmaterials was studied on citrosum.Based on formal research results of single inhabitor anti-browing effects and orthogonal experiment,the optimum combined inhabitor and the reasonable anti-browing effects were obtained.The results showed that the activity of polyphenoloxidase in young buds was highest and young leave was lowest;the anti-browing effect sequence of single inhibitors was PVP〉ascorbic acid 〉aitric acid 〉AC.The best composition of combined inhibitors was 0.2% ascorbic acid,0.4% PVP and 0.5% aitric acid.
