Abstract
The main idea of this extended essay is to investigate the rate of germination of the specialized seeds (Lactuca Sativa) with the change of wavelength of the light. My research question is “How does different wavelengths of light affect the rate of germination as measured by observing number of sucessfully germinated seed of Lactuca Sativa under the influence of the same temperature, volume of water, time of enlightening ?” and my hypothesis for this extended essay is ” It can therefore be hypothesized that as we increase the wavelength of the light germination rate of Lactuca Sativa will be increase.” With these ideas I have planned and designed my own method in order to answer my research question and prove my hypothesis. While doing this experiment I have used a germination pot, led lights and lettuce seeds. The setup was planned as; each trial poured with water at first day(30ml) and the fifth day(10ml). Also in order to decrease the errors I have used same brands seeds because it decreases the variety between each seed. I put 50 seeds to each trial and enlightened them with different wavelengths of light; red, green, yellow, blue, violet. At the end of collection of datas I compared them with each other, however I have seen that, an error occurred during the germination process of seeds. If we compare the data ignoring the errors caused by several external factors, I can conclude that as the wavelength of light increases germination rate will increase. Moreover, according to ANOVA test there was a significant mean difference between the number of germinated seeds. I have used lettuce seeds because these seeds are photo dormant seeds and I can obtain observable results.
