Abstract

Abstract

To determine the effects of aluminum stress on the mineral contents in the seedlings of Chinese fir,apot experiment was conducted.Changes in the mineral contents of the roots and leaves of the seedlings induced by varying the aluminum in soil were monitored and analyzed statistically for possible correlations among them.The aluminum contents in the soil were adjusted to be 0,50,100,150,and 200mg·kg-1.The results showed that the contents of B,Mo,K,Fe,and Mn in the roots increased initially and decreased subsequently with increasing aluminum.It indicated that absorption of the elements by the plants was promoted at low level,but inhibited by excess aluminum presented in the soil.The content of B in the leaves showed a similar trend as well.In the leaves,the content of Mo increased slightly only at high level of aluminum,while K,Fe and Mn increased with the increasing aluminum.The statistical analysis showed that B had a significant correlation with both Mo and Fe in the roots,while that between Mo and Fe was highly significant.In the leaves,B significantly correlated with Mn,while Fe with both Mo and Mn.Moreover,there was a significant or highly significant correlation between K and other 4minerals.
