PHYTOCHEMICAL ANALYSIS OF NICOTIANA TABACAUM L UNDER HEAVY METAL LEAD (Pb) STRESS
Muhammad Saif Ullah
Abstract
Nicotiana tabacum L is a well-known crop of Swabi and people called it the land of maize and tobacco. Nicotiana tabacum L play a vital role in the economy of a country because of its high price and demand over worldwide. My present study aimed to observed the effect of Salicylic acid on the phytochemical substances of Nicotiana tabacum L grown under Heavy Metal Lead Stress. After Propagation Nicotiana tabacum L treated with Pb stress at different concentration like 5ppm, 5ppm+Sa, 9ppm, 9ppm+Sa and Control. Results revealed that those plants which have treated with Pb stress like 5ppm and 9ppm showed decline in the phytochemical substance like CAT, PO, ROS, GA3 AND ABA. While those plants which have treated with Pb as well as Sa like 5ppm+Sa and 9ppm+Sa showed progress in the phytochemical substances of Nicotiana tabacum L. Therefore, I can say that salicylic acid is the key product to remove the heavy metal stress and promotes the primary and secondary growth of Nicotiana tabacum L.
