Effect of Salinization on Germination of Radish Seeds Abstract: The buildup of salt concentration is becoming a major problem on farmland in the world. When salt is a factor, seeds become dehydrated and can’t prosper. It is important for farmers to recognize this issue and assess the healthy salinity levels on their farms. This experiment was tested on a small scale with a small sample size. Different salt concentrations were placed in a bag with 10 radish seeds and over the course of 3 days experimenters observed the percentage of germinating seeds. The hypothesis for this experiment is that with lower salinity levels, more seeds will germinate. Knowledge of these results can help farmers everywhere increase the survival rates of their crops. After completing the lab, it was determined that seeds were in fact affected by salt concentration levels. Seeds exposed to minimal salinity levels germinated the most successfully and seeds in contact with high levels of salinity had very low germination levels, if any germinated at all. These results can build farmer’s knowledge of seed germination when in contact with salt. They can now test for salinity levels when growing crops to ensure the best results. Introduction: Small amounts of salt build up in Earth’s soil. This buildup of salt can imbed in germinating seeds and actually effect the growth of these seeds. Although it takes a large salt concentration to do any damage, it is very important for farmers to the relationship between salt concentration and the percent of seeds that will germinate. Salt kills germinating seedlings by removing the water from their cells. The ecosystem is filled with many different salts but this lab will involve only Sodium Chloride (NaCl). Hypothesis: If there is a larger consumption of salt, then less radish seeds will germinate. Once there is 1.5 grams/100 mL H₂O of salt no
