Conclusion:
The aim of this experiment was to investigate whether or not salinity of the water solution will affect the speed of germination and the quantity of seeds germinated during a period of 7 days. The experiment was designed so that the seeds were exposed to appropriate amount of water and set in an environment that was the most appropriate to the Daikon Radish seeds (the seeds used in the experiment). The only factor that was purposely changed during the experiment was the salinity of the water the seeds were exposed to. The hypothesis of the experiment was “Seeds exposed to 1.0 g of salt will take longer to germinate. Seeds exposed to 0.5 g of salt will germinate faster, however seeds exposed to no additional salt will germinate at the greatest speed”.
As I have mentioned in the report, in the observation section, there were limitations to the accuracy of the data collected. During the experiment I have followed certain safety restriction, as not to cut myself when preparing the cups for the experiment. I have also been careful not to adjust the data in a way that would accept the hypothesis in a false way.
The data collected shows that seeds that were exposed to higher levels of salinity showed less productivity and the speed of germination was reduced to minimum. Seeds that were exposed to little salt (0.5 g) showed higher productivity that the ones exposed to 1.0 g of salt, however the data was still lower than the data on the seeds that were held in regular tap water. This information collected showed that seeds exposed to 1.0 g of salt would take longer to germinate, seeds exposed to 0.5 g of salt will germinate faster, however seeds exposed to no additional salt will germinate at the greatest speed, therefore supporting my hypothesis completely.
