[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.
