Plants rely on environmental signals, such as gravity, to regulate their growth and gather resources. Hypergravity, an increased gravitational force beyond Earth’s 1 x g, has been reported to induce various phenotypic, physiological, and structural changes in plants. In this study, mung beans (Vigna radiata) were subjected to hypergravity treatment using a standard laboratory centrifuge. Seeds were exposed to various gravitational values (100 and 1000 x g) with different durations (1, 2, 4 hours). The seeds were then germinated under normal growth conditions. After 7 days, germination percentages and root lengths were assessed to determine the impact of hypergravity on early plant development. Regardless of duration, all seeds exposed to 1000 x g showed a significant decrease in root length compared to the control. However, exposure to 100 x g for 4 hours showed a significant increase in root length by 3.17% (p < 0.05). The results indicate that mung beans respond differently depending on the strength and duration of hypergravity. Higher gravitational forces (1000 x g) slowed down root growth, suggesting that low to moderate gravity may enhance root development in early stages. These findings suggest that hypergravity treatment could confer changes in growth traits in mung beans, offering a potential strategy for improving crop resilience to various environmental stressors. Further investigations involving molecular and biochemical analyses are warranted to fully understand the underlying mechanisms and broader implications of hypergravity-induced plant responses.
