Gamma irradiation is the technique used to induce plant mutation and it has affected both the physiological and biochemical compounds of the plant. Some new rice lines are also created through the gamma-irradiation technique. We investigated the effect of gamma irradiation on plant growth, volatile compounds, and the biological activity of gamma-irradiated rice extract compared to non-gamma-irradiated rice extract. The results reveal that the gamma-irradiated rice growth was related to the proline content, as the low gamma dose induced rice growth and proline accumulation in gamma-irradiated rice. We induced the bioactive compounds, including the flavonoid content and phenolic content of gamma-irradiated rice, through the low gamma irradiation dose at 60–100 Gy. Interestingly, bioactive compounds were stimulated by a gamma dose similar to that of the biological activity (antioxidant activity and enzyme inhibition) of gamma-irradiated rice. The results suggest that gamma-irradiated rice extract's biological activity was closely related to the flavonoid and phenolic content of rice. We also identified the variety of volatile compounds in gamma-irradiated rice and they were also reported for the biological activity. Our results can generate a new rice line that exhibits high plant growth and is rich with bioactive compounds such as flavonoid and phenolic compounds which are related to the improvement of human health.

伽马辐射是用于诱导植物突变的技术，它影响了植物的生理和生化化合物。一些新的水稻品系也是通过伽马辐射技术产生的。我们研究了 γ 辐照对植物生长、挥发性化合物的影响，以及与非 γ 辐照大米提取物相比，γ 辐照大米提取物的生物活性。结果表明，γ辐照水稻的生长与脯氨酸含量有关，因为低γ剂量诱导了γ辐照水稻的水稻生长和脯氨酸积累。我们通过 60–100 Gy 的低伽马辐照剂量诱导了生物活性化合物，包括伽马辐照大米的黄酮类化合物含量和酚类含量。有趣的是，生物活性化合物受到与 γ 辐照水稻的生物活性（抗氧化活性和酶抑制）相似的 γ 剂量刺激。结果表明，γ-辐照大米提取物的生物活性与大米的黄酮类和酚类含量密切相关。我们还鉴定了 γ 辐照大米中的各种挥发性化合物，并报告了它们的生物活性。我们的研究结果可以产生一个新的水稻品系，该品系具有高植物生长，富含生物活性化合物，如与改善人类健康有关的黄酮类和酚类化合物。其生物活性与水稻的黄酮类和酚类含量密切相关。我们还鉴定了 γ 辐照大米中的各种挥发性化合物，并报告了它们的生物活性。我们的研究结果可以产生一个新的水稻品系，该品系具有高植物生长，富含生物活性化合物，如与改善人类健康有关的黄酮类和酚类化合物。其生物活性与水稻的黄酮类和酚类含量密切相关。我们还鉴定了 γ 辐照大米中的各种挥发性化合物，并报告了它们的生物活性。我们的研究结果可以产生一个新的水稻品系，该品系具有高植物生长，富含生物活性化合物，如与改善人类健康有关的黄酮类和酚类化合物。
