The Zn concentration in leaf and leafstalk increased with increasing Zn supply from 0 to 160 mgL^(-1), but had no increase or even decreased when the Zn supply was higher than 160 mgL^(-1). The Zn concentration in root exhibited a positive correlation with Zn supply and its exposure time, and the kinetic curve of Zn uptake fitted linear-quadratic model, i.e., fast linear uptake first and slow saturation uptake later, with the dividing point at about 1-2 hours' exposure, which could be related with the Zn adsorption on root cell wall and the Zn transportation across the cell membrane.

在0160 mgL^(-1) Zn处理下，植株叶片和叶柄Zn含量随Zn处理水平的提高显著增加，Zn浓度大于160 mgL^(-1)后，植株叶片和叶柄Zn含量不再随介质中Zn浓度的提高而增加，根系含Zn含量与介质中的Zn浓度和培养时间呈正相关，且根系Zn吸收动力学曲线具有二型性，即开始为快速的线性吸收，随后是较缓慢的饱和吸收，两者分界点约在12h，这可能分别与根细胞壁吸附Zn和Zn跨根细胞膜运输有关。
