Hypergravity, defined as a gravitational force greater than Earth’s 1×g, has been shown to trigger a range of phenotypic, physiological, and structural responses in plants. In this study, we investigated whether hypergravity, influences the salinity tolerance of mung beans (Vigna radiata) during early germination. Results from a two-way ANOVA indicated that salinity had a significant inhibitory effect on sprout length (p < 0.05), while gravity alone did not exhibit a statistically significant main effect. However, a significant interaction between salinity and gravity (p < 0.05) revealed that hypergravity exposure alleviated the negative impact of high salinity on seedling elongation. These results suggest that hypergravity can partially mitigate the negative effects of salinity on sprout growth. Understanding how short-term hypergravity, encountered during launch and transit, influences plant stress responses can support the development of resilient crop systems for sustained food production in space.
