Abstract: A greenhouse experiment was performed for one year to research the effect of wastewater on Kandelia candel seedlings. Artificial seawater was used as the control, three different strengths of artificial wastewater had been discharged into the simulated system in fixed time and quantity. Results showed that the Kandelia candel seedling had a high potential resistance to artificial wastewater by changing its physiological activities and microstructers in all plant organs to adapt the pollutants within wastewater, but the growth of root was restricted with wastewater to some extent.

Key words: Kandelia candel, artificial wastewater, morphology, anatomical structure
