[Effects of nitrogen and calcium on polyphenol oxidase, peroxidase and leaf spot in carnation].
Carnation inoculated with leaf spot was cultivated under different concentration of nitrogen and calcium in this experiment. The result showed that the nutrition state [NO3- (0.024%-0.025%), Ca2+ (0.022%-0.0342%)] was helpful to keep higher activity of POD and PPO and enhance the carnation's resistance to the germs.
