Radiosensitivity Assessment and the Impact of Gamma Radiation on the Growth and Diversity of Pennisetum purpureum Cv Mot in Marginal Land

Abstract

This study aims to assess the radiosensitivity of Pennisetum purpureum cv Mott, with the primary objectives of determining the LD50 value, evaluating the effects of gamma radiation doses on plant growth and diversity, and elucidating the specific goals of irradiation in relation to the overall research. The research encompasses a wide range of radiation doses, ranging from 0-400 Gy, including multiple double doses (×2 Gy). The investigation involved irradiating Pennisetum purpureum cv Mott seeds (cuttings) and observing their seed germination capacity after one month. This research was conducted with rigorous scientific methodology, involving five replicates, each consisting of 100 plants. The study was carried out in marginal land conditions with a pH range of 4.5-5. These specific experimental conditions were chosen to simulate real-world scenarios and provide valuable insights into the radiosensitivity of Pennisetum purpureum cv Mott under conditions similar to those found in marginal agricultural areas. It is noteworthy that this study represents a novel contribution to the field of radiosensitivity in plants, as it differs significantly from previous research endeavors. This research offers a fresh perspective and distinctive findings that set it apart from prior studies. In addressing ethical standards, it is essential to note that this study strictly adhered to ethical considerations, particularly regarding the use of radiation on plants. All procedures were carried out in accordance with established ethical guidelines and compliance with radiation safety protocols. The findings reveal that radiation doses significantly influence seed germination and the morphology of leaves, stems, and roots in Pennisetum purpureum cv Mott. The study indicates that the Lethal Dose 50 (LD50) for Pennisetum purpureum cv Mott is approximately 28.79 Gy. Furthermore, a diverse range of traits, including leaf count, leaf length, plant height, stem length, and stem diameter, exhibit varying degrees of heritability, with coefficients of genetic variation (KKG) ranging from low to very high. In conclusion, this comprehensive and novel study sheds light on the impact of gamma radiation doses on Pennisetum purpureum cv Mott. The results are instrumental in understanding the radiosensitivity of this plant species and hold potential applications in agronomy, especially in marginal land cultivation. Furthermore, this research contributes to a deeper understanding of radiation effects on plants, specifically within the context of Pennisetum purpureum cv Mott in marginal land conditions while adhering to ethical standards and introducing novel insights into the field.
