摘要：The impact of ozone and α-tocopherol on Withania somnifera has been assessed withreference to plant height and leaf area. The control plants of Withania somnifera attaineda height of 21.43 cm in 30 days. Their fully expended leaves attained 37.74 cm 2 area(per leaf). Ozone exposure resulted in a sharp decline in plant height and leaf area.The percentage decline was 70.14 % and 52.60 % respectively. The simultaneousapplication of α-tocopherol with ozone exposure nullified the ozone impact. In 200 ppmα-tocopherol, the plant height mounts to 22.47 cm which is even more than that ofcontrol. Similarly, the negative impact of ozone on leaf area was almost neutralized by200 ppm α-tocopherol.
