Experiment: The Effect of Different Temperatures on Germinating Beans

Our experiments examined the effect of different temperatures on germinated legumes and the cell respiratory effectiveness of these beans under these different conditions. We carried out two experiments. The first temperature is 22 ° C and the second temperature is 13 ° C. Both are independent variables. Next, we measured the amount of carbon dioxide and oxygen from the container of beans as a dependent variable. Our hypothesis is that breath of germinated beans is most effective at room temperature.

The purpose of this experiment was to investigate the effect of different concentrations on the germination of mung bean seeds by copper ions. This experiment used seed germination as a parameter to present different concentrations of copper ion solution (Cu 2+) in copper sulfate (ii) (CuSO 4). The solutions used were 300 ppm, 200 ppm, 100 ppm, 75 ppm, 50 ppm, 25 ppm and 0 ppm and the seeds were soaked for 6 hours and then seeded in a petri dish with a wet cotton layer. Seeds were watered with the same volume of Cu 2+ solution at each concentration. The number of germinated seeds was recorded after 20 hours and the germination rate was calculated. The results showed that the germination rate increases as the concentration decreases.

In the laboratory, the relative amount of O 2 consumed by germinated pea and ungerminated pea at room temperature and 10 ° C. was measured. The main aim was to discover the effects of germination and temperature on the respiration rate of the cells. The results showed that respirometer with germinated pea has higher cell respiration rate than ungerminated pea and cell respiration is faster at 10 ° C. Experiment demonstrates the influence of environmental factors on cell respiration

One limitation of this experiment is to change the ambient temperature. Seeds whose temperature can vary over time are left in the laboratory. This may affect the germination time of the seeds and the number of germinated seeds after 36 hours. It is not controlled except for temperature, humidity, luminous intensity. All seeds are exposed to the same environmental factors, so the results are considered reliable. However, restrictions can be overcome by using multiple seeds and repeat the experiment several times to ensure that the results obtained are reliable and sufficient to support the conclusion. In this study, we tested the effectiveness of the vitamin C solution on the seed germination without exposing the seed to other biological stresses such as abiotic stress such as salinity or exposure to sunlight.
