Evaluation of Effect of Zinc Oxide and Zinc Solubilizing Bacteria on Morphological and Enzymatic Activities on Radish Raphanus Sativus L

Zinc is an essential micronutrient required by all plants in variable concentrations but certain inherent properties of soil make the accessibility of Zinc a problem for crop plants. Different approaches can be use to increase Zn uptake by plants, one of which can be the application of Zinc solubilizing bacteria ZSB . Although highly useful but only a handful of studies document the effect of concentration of Zinc Oxide with different inoculants of bacteria. Various PGPR have found to be effective zinc solubilizers. These bacteria improve the plant growth and development by colonizing the rhizosphere and by solubilizing complex zinc compounds into simpler ones, thus making zinc available to the plants. Various PGPR have shown enhanced growth and Zinc content when inoculated in plants. These include Pseudomonas, Bacillus sp., and Azospirillum. To investigate the physiological and biochemical basis with Zinc oxide ZnO and inoculation of plant growth promoting rhizobacteria in Radish plants Japanese White Radish . Four different strains of bacteria were used i.e. MTCC 102 – Pseudomonas putida, MTCC 103 – Pseudomonas fluorescens, MTCC 121 – Azospirillum lipoferum, MTCC 2694 – Bacillus subtilis, and untreated Control in field of Radishes. Field and Laboratory experiments were conducted in Department of Botany and Botanical garden at DAV University Jalandhar. Results of our study indicate that morphological data Fresh Weight, Dry Weight of Radish Plants , and Chlorophyll Content, Catalase activity and Protein Estimation Content showed the best performance with application of ZnO and PGPR as compared to the plants with no external treatment on Radish plants.
