Abstract: In order to explore function of different mineral element to Arabidopsis calcium accumulation,we used different concentration of Ca2＋, K＋, NO3-, Mg2＋, S04〉, NH4＋, P04〉, Fe〉, Zn〉 base on the hydroponic system and choose Arabidopsis as material.In this system,while the concentration of NH4＋ was 10 mmol/L,the accumulation of calcium reduced dramatically. While the concentration of K＋ was 0 mmol/L, the accumulation of calcium increased obviously. Under the low and high concentration of Mg2＋, Fe2＋, Zn〉, the accumulation of calcium all reduced markedly. It is suggested that NH4＋, K＋, Mg2＋, Fe2＋, Zn〉 possessed obvious effect on the accumulation of calcium.
