EFFECT OF LEAD TOXICITY ON THE GROWTH OF RICE (ORYZA SATIVA L.) PLANT
TALIYAH SHAUKAT
Abstract
Much of the world’s population relies primarily on rice (Oryza sativa L.) as one of their main staples; however, heavy metals like lead harm the crop's yield. Heavy metals refer to any metallic chemical element with a comparatively high density that is dangerous or poisonous in small amounts. The present study aimed to compare the toxicity level and its effects on the rice (Oryza sativa L.) plant under different concentrations of lead and investigate the response of the rice (Oryza sativa L.) plant under lead toxicity. In the present study, the Basmati rice seeds (PK 1171) were treated with three different lead acetate Pb (CH3COOH)2 concentrations (0, 250 ppm, 500 ppm, and 1000 ppm) to evaluate the effect on morphological parameters. Lead treatments caused significantly (p ≤ 0.05) reduced the number of leaves (-24%), shoot length (-39%), seed vigor index (-39%), root length (-42%), fresh plant weight (-49%), dry plant weight (-28%), leaf area (-55%), leaf area index (-80%), and specific leaf area (-41%). Lead also reduced the relative water content and tolerance indices, measured at 84% and 58%, respectively. The whole result showed that lead-treated plants harmed plant growth.
