Comparison of botanical characteristics of cultivated Chrysanthemum morifolium cv.'Hangju' of different origins

Objective To compare botanical characteristics of cultivated Chrysanthemum morifolium cv. 'Hangju' of different origins in order to provide the basis for introduction and cultivation of Ch. morifolium cv. 'Hangju'. Method The characteristics of plants, leaves and capitulum of Ch. morifolium cv. 'Hangju' were measured, and the obtained data were analyzed and compared. Result The range of plant height was 60.87-99.47 cm, number of branches 2.76-5.20, leave length 4.90-8.40 cm, leave width 3.25-5.38 cm, aspect ratio of leave 1.35-1.83, number of leave split 1.92-3.08. Numbers of capitulum were 21.92-53.12, diameter of capitulum 3.41-5.48 cm, lays of ray florets 3.28-7.16, number of ray florets 55.32-114.60, ray florets length 1.58-2.37 cm, ray florets width 0.50-0.69 cm, aspect ratio of ray florets 2.90-3.99, diameter of tubular flower 1.10-1.58 cm. Conclusion The botanical characteristics of cultivated Ch. morifolium cv. 'Hangju' were distinguished from different origins. With the cultivation environment change, the botanical characteristics of the cultivars are changed.
