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.

摘要

采用电感耦合等离子体发射光谱法（ICP - AES）分析了野菊花不同器官中的矿质元素。结果表明：（1）在大量元素中，根、茎、叶和花中钾的含量最高，分别可达15.84、17.74、31.52和37.55 mg x g(-1)，而在微量元素中，根、茎、叶和花中铁的含量最高，分别可达3219.90、433.36、1519.46和1426.63 μg x g(-1)。（2）野菊花茎中钾、磷、钙、镁、锰、锌和钼的积累量最高，分别可达240.61、19.67、74.87、18.31 mg x 株(-1)以及893.00、1039.08、2.85 μg x 株(-1)，而钠、铁和铜的积累量在根中最高，分别可达11.51 mg x 株(-1)、11725.27 μg x 株(-1)和235.24 μg x 株(-1)。（3）不同器官中钾:磷、钙:镁、铁:锰、锌:铜的比例各不相同。该研究结果明确了野菊花不同器官中的矿质元素，将为施肥提供科学依据。
