本文研究了红茶、花茶和绿茶对果蝇寿命的影响。实验组培养基中茶的浓度分别为5％、10％和15％;对照组用基础培养基。结果发现红茶、花茶和绿茶三组果蝇的寿命均显著高于对照组(P<0.05),表明茶叶有明显延长果蝇寿命的作用,其中以红茶效果最好。 This paper studied the effects of black tea, flower tea and green tea on the life span of fruit flies. The concentration of tea in the medium of the experimental group was 5%, 10%, and 15%, respectively; the control group used basic medium. The results showed that the life spans of black tea, flower tea and green tea were significantly higher than those of the control group (P<0.05), indicating that tea had a significant effect on prolonging the lifespan of fruit flies, with black tea being the best.
