Abstract
The effects of magnesium(Mg) deficiency on the growth and assimilation of mineral nutrition of cucumber seedlings were studied through hydroponic experiment.The results showed that: under the Mg deficiency stress,(1) the dry weight of cucumber roots,stems and leaves reduced significantly;(2) phosphorus concentration increased conspicuously up to 2.11% in leaves,but had no change in roots;potassium concentration did not change in roots and leaves;calcium concentration increased significantly in roots and leaves,it reached 73.7 g/kg in leaves;(3) the concentration of manganese(Mn),iron(Fe) and zinc(Zn) increased both in roots and leaves,especially for Mn,Fe concentrations in roots and Mn,Zn concentrations in leaves,they were twice as much as or even higher than those in the control treatments,respectively;and copper increased in leaves,but had no change in roots,compared with the control.
