The term “beans” is generally used as a blanket name for common beans, fava or broad beans, soybeans, chickpeas, lentils, and seeds of various other plants, under the bean family or Leguminosae family of flowering plants (Angiosperms). ... and collect data on rates of germination, growth, etc. This is one of the easiest plant science projects you will ever do – the bean plant experiment for kids. : To calculate the germination rate, I took the number of seeds that germinated during that time and divided by 10. Seed Germination 2362 Words | 10 Pages. This process was recorded after one week. 4 kidney beans; The next morning, we peeled the seed coat off of half of the beans. The germination rate of dry beans decreases significantly with age and is impacted by storage conditions. Bush varieties tend to do better in more confined spaces. The two lima bean plants that grew averaged a height Germination experiment. I planted some pinto bean seeds and kept them in the dark to see if they would grow. Pond: Out of the five kidney bean plants that grew the average height was found to be 15.3 centimeters. We evaluated seed germination under two conditions: a 12-h daily photoperiod (hereafter ‘light’) and one in continuous darkness (hereafter ‘dark’) in a germination chamber for 30 days. The experiment looks at moisture, light, acidity, and other factors that may affect germination. Mung beans, which are used as "bean sprouts" when they have sprouted would be a good substitute in this experiment. The kidney bean is a variety of the common bean (P. vulgaris), so named because of its kidney-like shape and its colour.The optimum moisture range is 12–14%.
