Objective:
Compared the difference of the configuration of vegetative organs of medicinal Chrysanthemum in the same habitats but from various original locations and species, in order to provide scientific basis for the study of introduction, differentiation within the species, breeding and genetic diversity.
Methods:
The experimental plot were divided into some groups randomly in design and the configuration of vegetative organs were observed, measureed and analysed.
Results:
The differences of the type and shape of the leaves were obvious. All the Chrysanthemum morifolium cv. 'Gongju' had deep notch long-leaves; Chrysanthemum morifolium cv. 'Boju', Chrysanthemum morifolium cv. 'Chuju', Chrysanthemum morifolium cv. 'Hang bai ju' and Chrysanthemum morifolium cv. 'Hang huang ju' had deep notch correctitude-leaves; Chrysanthemum nakingense and Chrysanthemum indicum had long-leaves; Chrysanthemum indicum had clump-leaves. All the 12 medicinal Dendranthema material had auricle except Chrysanthemum morifolium cv. 'Boju' and Chrysanthemum morifolium cv. 'Chuju'. The young leaves of Chrysanthemum morifolium cv. 'Gongju', Chrysanthemum morifolium cv. 'Gongju' and Chrysanthemum morifolium cv. 'Hang bai ju' did not split and the rest were all splitting.
Conclusion:
The differences of the configuration of vegetative organs were obvious and the Key of Vegetative organs was built.
