Abstract:
Rice (Oryza sativa L.) is third important cultivated crop in Pakistan and it is second staple food of our country. It is the primary source of energy for half of the world population and is enriched with protein, vitamins, fibers and other essential nutrients. The present study was aimed to evaluate the effects of foliar application of fulvic acid (FA) and silicon dioxide (SiO2) on growth, yield and quality of rice as well as their molecular interaction with enzyme through molecular docking. The treatments in the study were used as FA (0.5ml) and SiO2 (0.6ml) individually as well as in combination FA+SiO2 (0.5 + 0.6) ml. The experiment was conducted at Seed Center, University of the Punjab, Lahore. All treatments significantly affected all the parameter under study compared to control. However, the combined application of FA+SiO2 was more efficacious than individual. The results depicted that combined treatment of FA+SiO2 significantly increased the leaf length (27.16cm), leaf width (0.39cm), leaf area (7.47cm2), number of leaves (5.50), number of tillers (13.00), plant height (46.16 cm) similarly the biochemical parameters including chlorophyll (0.60 mg g-1) and carotenoid (6.52 mg g-1) increased significantly by the combined treatment of FA and SiO2. However, the remarkable increase was observed in yield parameters such as grain fill rate (9.38), panicle length (13.83cm), 1000-grain weight (31.12g), yield per plot (408.75g) at sole application of SiO2. The nutritive value of rice such as dry matter, crude protein, crude fiber, fats and ash were found to be influenced by exogenous application of these treatments. Moreover, molecular docking of FA through Auto dock tool 1.5.7 also give the precise bonding with protein dehydroascorbate reductase (DHAR) at molecular level.
