RESUMEN
OBJECTIVE: To study leaf ultrastructure in varieties of Chrysanthemum morifolium. METHOD: The ultrastructure of leaves was observed through the transmission electron microscope. RESULT AND CONCLUSION: 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.

OBJECTIVE: To study the effects of climate factors on the Chrysanthemum morifolium originated from Wenxian county (i. e "huaiju") for assuring the quality of medicinal C. morifolium. METHOD: The content of water-soluble extracts, protein, sugar, flavonoid and chlorogenic acid of "huaiju" collected from Henanwenxian, Jiangsunanjing and Zhejiangtongxiang were selected as the indicator and determined, climate data of the corresponding places were collected for studying the effects on "huaiju" quality through path analysis and correlation analysis. RESULT AND CONCLUSION: There existed no obviously differences among the detected indicators except the soluble sugar content. Sunlight, temperature and precipitation showed more effects on quality of "huaiju", the sunlight had the most direct effect on flavonoid, the 10 cm ground temperature had the most direct effect on chlorogenic acid.
