十三个"汴京系列"地被菊花期及花器官色彩分析OA

Thirteen'Bianjing Series'ground cover chrysanthemums were used as experimental materials to study and observe the characteristics of important ornamental traits such as flowering phenology and flower type,in order to provide reference for the breeding and garden application of this series of ground cover chrysanthemums.The results showed that'Bianjing Xiaohuangqiu''Bianjing Hongsirong''Bianjing Zirongrong'and'Bianjing Xiaofentuan'had the earliest color stage,first flowering stage and full flowering stage.'Bianjing Hongri''s average was the latest;'Bianjing Qingdianhuang'had the longest total flowering period of 44 days,and'Bianjing Xiaotaiyang'had the shortest flowering period of 28 days.The 13 ground cover chrysanthemum types were divided into two types,flat petals and tubular petals,'Bianjing Honglingguan'was the tubular petal,and the rest were flat petals,all of which belong to the small chrysanthemum family.The color was divided into 3 color systems,yellow,red and pink.The color measurement results of the colorimeter showed that the brightness(L*)and the highest chroma(C*)of'Bianjing Xiaohuangqiu'were the highest,and its color was the most vivid.The ground cover chrysanthemums contained different degrees of anthocyanins and carotenoids,and the anthocyanin content of'Bianjing Hongsirong'was the highest(16.960 mg·g-1)and its petals were red.The carotenoid content of'Bianjing Qingdianhuang'was the highest(0.137 mg·g-1),and its petals were yellow.The whole petal cell fluid was acidic(pH 5.577-5.993).
