The performance of Vicia faba L. in soil amended by different concentrations of fly ash has been studied. The parameters considered are seed germination, growth behaviour and nodulation frequency of the plant. Results revealed that while fly-ash amendment to the soil improved the growth performance at initial stages with application of lower concentrations, it was inhibitory at higher exposure concentrations. Although there was no difference in survival rates, but the seedling growth was reduced in comparison to control plants. Fly ash delayed the nodulation as lesser number of nodules was recorded at higher amendments. Results suggested feasibility of growing V. faba in fly ash contaminated area.
研究了不同浓度粉煤灰改良土壤中蚕豆（Vicia faba L.）的表现。所考虑的参数包括植物的种子发芽、生长行为和结瘤频率。结果表明，虽然在较低浓度下向土壤中添加粉煤灰在初始阶段改善了生长性能，但在较高暴露浓度下具有抑制作用。虽然存活率没有差异，但与对照植物相比，幼苗生长有所减少。粉煤灰延迟了结瘤，因为在较高添加量下记录到的根瘤数量较少。结果表明在粉煤灰污染地区种植蚕豆是可行的。
