Res lts showed that the K andelia candel seedling had a high potential resistance to artificial w astew ater by changing itsphysiological activities and microstr cters in all plant organs to adapt the poll tants within wastewater, b t the growth of root w as restricted w ith w astew ater to some ex- tent.
