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).
