Evaluation of stability of characteristics in seasonal low temperatures of spray cut chrysanthemum
Abstract：Spray cut chrysanthemum varieties in seasonal low temperatures differ in their stability of characteristics,to evaluate stability of characteristics,the height of the stalk, the thickness of the stem, the diameter of the flower, the height of the branch, the number of branches and the length of the branch were studied in 31 cultivars.Principal component，subordinate function analyses and one-way analysis of variance were used. Results showed that the characteristics of ‘Xuesong’，‘Xiaocaomei’，‘Jingli’，‘Xiaozikou’and‘Yanzhi’were very stable.The characteristics of ‘Ziyunying’，‘Liangfengdian’ ，‘Beileisi’，‘Xiangcunyinyue’，‘Zizhu’，‘Songmang’，‘Fenbaijianse’，‘Yuhu’，‘Qiaofengche’，‘Mengshenfen’and ‘Mengbai’were relatively stable.However,the characteristics of ‘Daihua’，‘Liangchendian’，‘Yunyi’，‘Binjie’，‘Baidiandian’，‘Biyun’，‘Fangzhou’，‘Fenying’，‘Hongdiandian’，‘Fendujuan’，‘Honglou’，‘Lianghongdian’，‘Dianyou’，‘Daifen’and‘Xiaojinxing’ were not stable.What’s more,the low temperature have a great impact on the flower and branch of spray cut chrysanthemum.The diameter, the amount of flowers and the number of branches were significantly lower than the control group.
