Phytoremediation capability and growth parameters of some tree species irrigated with treated sewage water a- vegetative growth

الملخص EN

This research was carried out at Serapium plantation located in northeastern Egypt on March 2019, to study the growth rate of three tree species Tectona grandis (Linn.

), Gmelina arborea (Roxb.

) and Azadirachta indica (A.

Juss.

) irrigated with treated sewage water after six years of planting in two sites at Serapium plantation, the first site is virgin soil, planted for first time (site1), "afforestation" and the other one is replanted (site2), "reforestation".

Results showed good vegetative growth parameters for trees at (site2).

On the other hand, Gmelina arborea recorded the maximum tree volume (1.16 m³ / tree) compared with the other studied species.

Followed by Azadirachta indica (0.74 m³ / tree), then Tectona grandis (0.24 m³ /tree).
