Hydroponic experiment was carried out to analyse the effect of Zn on anti oxidative enzyme activity, zinc content in shoot and root of rice genotypes and zinc efficiency. The experiment was comprised of 20 genotypes and two treatments viz., T1: µM (Zndeficient); T2: µM (Zn-sufficient/control). Results indicated µM concentration of zinc sulphate significanty incresead the zinc content in shoot ( ppm) and root ( ppm), superoxide dismutase enzyme ( g-1 protien-1 ) and perioxidase enzyme activity ( mol min-1 g -1 protein) were measured on 4-week old seedlings. Screening of Znefficient genotypes carried out in hydroponic experiment, Halga and Kalanamk and Dodigya was recorded as most Zn-efficient genotypes, however Koorigenellu was found as Zn-inefficient genotype with respect to shoot dry weight. | Influence of Zinc on functioning of anti-oxidant enzymes and Zinc content in Hogland solution of rice genotypes
