Effect Of Temperature On Germination

Germination is the process in which a plant stems from a seed, and it is fundamental in the development of plants. There are factors that go into how a seed will germinate, one of the most important being temperature. It is said that temperature is an environmental factor that affects germination. Temperature can affect the percent and rate of germination in at least three different ways. The first being that since seeds deteriorate, unless germinated, and the rate of deterioration depends mostly on the moisture content and temperature. The second being that high or low temperatures can reinforce or induce dormancy within the seed, which means the seed, will not germinate. This can be an issue when it comes to varying temperatures since at …show more content…
When a seed is trying to germinate in temperatures that are too cold there is a negative effect on the energy of germination and the root length. There is also an increase in abnormal seedlings (Lekić et al 2015). But all of this information can vary depending on the type of seed it is. An experiment using Asafoetida it was found that varying temperatures produced better germination than a constant …show more content…
As proved in “Effect of Temperature Regimes on Seed Germination Asafoetida” seeds germinate better when the temperature is varying rather than when temperature is constant. We did not have the same results that this experiment did. In the control group 9/10 seeds germinated, while the seeds that had the high temperature had maybe 5 seeds germinate. After two weeks we found that the seeds that were in our control group, which was a constant temperature of room temperature. This experiment showed that seeds do not germinate as well in high temperatures. One of the factors that could have contributed to this was that the seeds that were on the heat mat dried out because the temperature made the water evaporate, and water is one of the key components of germination. One of the ways we erred in this experiment was not keeping the filter paper wet so that the seeds had the moisture to germinate. The rate of germination could have been higher for all seed groups if the seeds would have had the moisture they needed to germinate and the results would be more accurate that way. The purpose of this experiment was to see which conditions each seed germinated in best, and while our results were accurate I think that if the experiment were to be repeated and water could be added more often to eliminate that error the results would
