Using Ion Beam Irradiation to Evaluate the Morphological and Chemical Characteristics of Jasmine Cultivar Rice (Oryza Sativa L.) Under Drought Condition

Abstract

The continuous flow of water is crucial for the growth of rice, a staple meal in many nations of Asia. Hence, creating a rice genotype that is resistant to drought and low rainfall would help ensure the steady availability of rice around the world. The Oryza sativa L. genotype of Jasmine rice was evaluated for a number of drought-tolerance scenarios throughout this study. The genotype seeds were exposed to 350 Gy of gamma radiation before being placed into a basic Murashige and Skoog (MS) growth medium that was half strength and had been enhanced with polyethylene glycol 6000 (PEG 6000) concentrations of 20, 10, and 0%. The PEG 6000 had an impact on the lengths of the shoots and roots, weights of the dried and fresh seedlings, amount of total carbohydrates and chlorophyll, and proline build-up among other things. The average shoot length as well as the weight of the seedlings were highest among the seeds that had not been irradiated, whereas the average root length and proline concentration were highest among the seeds that had been irradiated. Additionally, the proline content increased as a result of the rise in PEG 6000 concentration. These results suggest that radiation has a beneficial effect on the ability of rice plants to withstand drought. In our opinion, the creation of a dependable genotype of rice that is drought-tolerant will enable increased food security through increased rice yield. Thus, further studies emphasising on this issue need to be in the pipeline.
