Bean and Pea Seed Propagation in Warm and Cool Temperatures Experiment Abstract: The hypothesis predicted that in warm temperatures, bean seeds would have higher germination rates and pea seas would have higher germination rates in cool temperatures. The experiment involved separating bean seeds and pea seeds into warm temperature groups and cool temperature groups. The seeds then were placed between two sheets of germination paper and placed in their respective temperature. After two weeks, data showed that bean seeds and higher, more successful germination rates than pea seeds in warm temperatures. Also, data showed that pea seeds had higher, more successful germination rates than bean seeds in cool temperatures. Overall, the hypothesis was supported by the data found in through the experiment and pea seeds should be grown in cooler temperatures, whereas bean seeds should be grown in warmer temperatures. Introduction: Seed propagation involves either the natural or assisted placement of seeds in favorable conditions to promote germination. By definition, germination is “the process by which a dormant seed begins to sprout and grow into a seedling under the right growing conditions” ( The purpose of this experiment was to investigate on which seeds have the highest germination rate in varying climatic temperatures. In terms of optimal germination temperatures, bean seeds tend to have a higher germination rate at warmer temperatures. Additionally, previous research had shown that “seeds [with similar qualities to bean seeds] stored at 4°C or under dry conditions lost their germination potential immediately” (Zarranz, E. M.). On the other hand, “Pea seeds will germinate as soon as daytime temperatures reach 40°F (4.4°C), although they may take 4-5 weeks to germinate when it's this cold” ( Therefore, a
