title: [Analysis of mineral elements in different organs of Chrysanthemum indicum L. based on ICP-AES].
abstract: ICP-AES technique was used to analyse the mineral elements in different organs of Chrysanthemum indicum L. The results show that: (1) The content of K in root, stem, leaves and flower was the highest among macroelements, and can respectively reach to 15.84, 17.74, 31.52 and 37.55 mg x g(-1), while the content of Fe was the highest in microelements in root, stem, leaves and flower, and can respectively reach to 3 219.90, 433.36, 1 519.46, and 1 426.63 microg x g(-1). (2) The accumulation of K, P, Ca, Mg, Mn, Zn and Mo was highest in stem of Chrysanthemum indicum L, and can respectively reach to 240.61, 19.67, 74.87, 18.31 mg x plant(-1) and 893.00, 1 039.08, 2.85 microg x plant(-1), while the accumulation of Na, Fe and Cu was highest in root, and can respectively reach to 11.51 mg x plant(-1), 11 725.27 microg x plant(-1), and 235.24 microg x plant(-1). (3) The proportion of K:P, Ca:Mg, Fe:Mn, Zn:Cu was varied in different organs. The results of the study pinpoint the mineral elements in different organs of Chrysanthemum indicum L. and will be a scientific basis for fertilization.
