In this paper, the main vegetative growth indexes of chrysanthemum such as height of plant, number of ground stem diameter, number of branches and the main reproductive growth indexes of chrysanthemum such as number of flower, weight of flower, diameter of flower, thickness of flower which were introduced and cultivated at different altitude in Baoxing of Sichuan Province were measured by field trials and the main quality indexes of the chrysanthemum samples such as content of Chlorogenic acid, contents of Luteolin and Isochlorogenic acid A were measured by laboratory analysis. The measured data were prossed by variance and correlation analysis to find the difference of plant growth and quality for medication of chrysanthemum which were introduced and cultivated at different altitude at high altitude area. The results showed that the vegetable growth index such as height of plant,the reproductive growth indexes such as number of flower, weight of flower, diameter of flower, thickness of flower and the quality indexes such as content of Luteolm and Isochlorogenic acid A of chrysanthemum were affected significantly by the elevation gradient at high attitude area(P>0.05). The vegetable growth indexes such as diameter of groung stem, number of braches and the quality index such as content of Chlorogenic acid of chrysanthemum were affected insignificantly by the elevation gradient at high attitude area (P<0.05). The vegetable growth index such as height of plant and the quality indexes such as number of flower, diameter of flower of chrysanthemum had a significant correlation with the elevation gradient at high attitude area (P<0.05). The elevation gradient at high attitude area had a significant effects on the plant growth of chrysanthemum exclude a few vegetable growth indexes such as the number of braches and diameter of ground stem. Within a certain range of altitudes(2 051--2 405 m) at high attitude area, the elevation gradient had insignificant effects on the quality formation of chrysanthemum. The quality of chrysanthemum all met the medicinal condition within the altitude of 2 051-2 598 m according to the minimum limits standard of active ingredients of chrysanthemum in the "Pepole's Republic of China Pharmacopoeia (2010 edition)" and the chrysanthemum had a best quality for medication which were introduced and cultivated around the altitude of 2 329 m. This study provided a theoretical basis for the introduction and cultivation of chrysanthemum for medication in the high altitude area. [ABSTRACT FROM AUTHOR]
