Dataset on the Effects of Mercury, Lead, and Copper Stress on Green Bean (Phaseolus vulgaris) Germination and Seedling Growth

This dataset contains experimental data on the effects of heavy metal stress (mercury, lead, and copper) on the germination and seedling growth of green beans (Phaseolus vulgaris). The study investigates the impact of varying concentrations of these heavy metals on key growth parameters such as germination potential, germination rate, root and shoot length, fresh and dry weight, and the accumulation of soluble carbohydrates and proteins. The findings reveal that mercury has the most pronounced inhibitory effect on both germination and seedling growth, while lead stress at certain concentrations may promote seedling dry weight, indicating potential adaptive responses. This dataset provides valuable insights into the physiological adaptation mechanisms of green beans under heavy metal stress, contributing to broader research on plant resilience and environmental pollution mitigation本数据集包含重金属胁迫（heavy metal stress）对菜豆（Phaseolus vulgaris）发芽及幼苗生长影响的实验数据。本研究探究了不同浓度的上述重金属对多项关键生长参数的影响，包括发芽势（germination potential）、发芽率（germination rate）、根长与茎长、鲜重与干重，以及可溶性碳水化合物与蛋白质的积累量。研究结果显示，汞对发芽与幼苗生长均具有最为显著的抑制作用；而特定浓度下的铅胁迫可促进幼苗干重，表明菜豆存在潜在的适应性响应。本数据集为解析菜豆在重金属胁迫下的生理适应机制提供了宝贵见解，有助于推动植物抗逆性与环境污染修复领域的相关研究。
