Abstract
Notice of Retraction

We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.

Ecological restoration of abandoned mining region has been one of urgent tasks in China. Some plants can play a key role in restoration of the abandoned mining wasteland owing to capability in accumulation of heavy metals. Koelreuteria paniculata trees grow well in the manganese mining wasteland with a survival percent up to 95.6%. In order to study ecological adaptation and resistant mechanism of K. paniculata to manganese pollution, seedlings of K. paniculata potted in six soil treatments set as tailings, tailing mud, fifty-fifty of tailings and soil, fifty-fifty of tailing mud and soil, admixture of fifty-fifty of tailings and tailing mud, and control soil continued for one year. Based on the experiments, the results showed that a) the content of Mn was obviously higher in lateral roots than that in stumps, leaves, and stems, whereas the content of Mn was lower in stems than all the other organs in all the treatments with the exception of lower content in leaves than that in lateral roots grown in the control, b) the content of Mn in the organs aboveground was below the critical standard for hyperaccumulators, c) the ratio of the content of Mn in organs aboveground to that in roots was not more than 1. These results indicated that K. paniculata was a kind of manganese resistant plant, not a manganese hyperaccumulator, and its manganese-resistant capability might be relative to accumulation of Mn in lateral roots and not translocating to the other organs aboveground.
