The measuring values of growth parameters of Solanum melongena were highly affected by the different stresses of O₃. The plant height was highly significant affected (P<0.0001) by ascorbic acid (AA) (32.66±8.08 cm/plant) followed by the control treatment (29.00±5.19 cm/plant) and the lowest highest was found by the plants grown in the second power plant (SPP II) (12.00±2.00 cm/plant). Moreover, the growth parameters were positively highly affected P< 0.001) by treatment of AA. The introducing of AA with the plants grown in the second industrial city (SIC II) which has an O₃ with a concentration of 136.66 pbb, didn’t significantly enhanced the growth parameters. The growing plants planted in SPP II (exposed to approximately 92 ppb) and enhanced by introducing of AA (SPP II+AA), exhibited the higher amounts of Chl a (27.45± 1.03mg g^-1 FW), Chl b (10.43±1.05 mg g^-1 FW), T Chl (47.35±3.41 mg g^-1 FW) and Caro (9.46±1.35 mg g-1 FW). On the other hand, the Pro content was affected by SIC II (8.69±0.61 g/100 g^-1 Fw), SIC II+AA (8.07±0.27 g/100 g^-1 Fw) and SPP II (8.92±2.08 g/100 g^-1 Fw). The different parameters of anatomical features or stomatal parameters and vessels diameters of S. melongena grown in the locations with high level of O₃ in comparisons with the control plants were significantly affected (P<0.0001).
