As a result of pollutants in the air, acid rain is a worldwide environmental problem that has severe consequences in plants and germination in seeds (Manisalidis, et al. 2020). Emulating the “acid rain” effect at home, different concentrations of vinegar solutions will be used to observe the germination rate of kidney beans. Kidney beans are one of many species that may be impacted by increasing acidity levels. In this study, we investigate
whether incremental increases in vinegar such as 0.1%, 1%, 2% and 5% would affect the time it takes for kidney beans to germinate. The kidney beans were pressed against a damp paper towel soaked with 4 different vinegar dilutions – 0.1%, 1%, 2%, and 5% over the course of 14 days. After 24 hours of overall incubation, 20 samples were observed daily. It was discovered that there was a significant difference between the 0.1% treatment group and the 1%, 2% and 5% treatment groups. Our results indicate that the lower vinegar concentrations are an effective environment for kidney bean germination, while higher vinegar concentration conditions are not.
