[Comparative study on leaf ultrastructure in varieties of Chrysanthemum morifolium].
OBJECTIVE
To study leaf ultrastructure in varieties of Chrysanthemum morifolium.


METHODS
The ultrastructure of leaves was observed through the transmission electron microscope.


CONCLUSIONS
Chloroplast, mitochondria, starch grains and peroxide were observed in the ultrastructure of leaves, but the organelle, ultrastructure and their quantity showed differences in various cultivars. The results may explain, why hangju'has a better resistance to the adversity and is planted in large scale.
