| 摘 要： | 本文对３个不同基因型玉米在不同磷水平培条件下，根系形态和Ｈ２ＰＯ＾－４吸收动力学参数的变化进行了研究。随供磷水平提高，根／冠比降低，根长增大，Ｋｍ和Ｃｍｉｎ提高，在缺磷条件下，白单１３对磷的亲合力（１／Ｋｍ）高于铁单４和四单８，吸磷临界浓度（Ｃｍｉｎ）也最低。

| Abstract: | in This paper, variation of root morphorlogital and P uptake was studied for three genotypes of maize under water culture of different P level. Root/cap ratio desend, root length K. and Cmin raise with P level raised. The 1/Km of Baidan 13 is higher than that of Tiedan 4 and Sidan 8, the Cmin of Baidan 13 is more lower. |

| Keywords: | maize genotypes P level root morphorlogical knietics parameter |
