The effect of flooding on the germination of a seed

Question
How is the germination of a seed affected by flooding?
Introduction
Seeds remain inactive until the right conditions present themselves for germination. To germinate the seed requires water, oxygen and the perfect temperature. Water and oxygen are taken through the seed coat and cause the seed’s cells to enlarge. A root will then emerge followed by the shoot containing the leaves and stem. Overwatering a seed will prevent oxygen from breaking though the seed coat. In many ecosystems flooding is a regular occurrence and is known to have dire effects on the environment. In extreme conditions floods create the wetlands habitat where plants and animals have adapted to deal with excess

Hypothesis
If more water is distributed to the seeds than the growth of the seeds will be limited.
Variables
The independent variable is the amount of water added to the seeds

The other germinated a day later

Discussion
The more water the seeds received the faster they germinated. This could be due to the fact that all plants need a combination of water and oxygen to germinate. From the results it can be seen that the mung beans needed at least 15 ml of water daily to germinate. The evidence does not support the hypothesis. The experiment could have been improved by substantially increasing the amount of water each dish received to fully measure the effect of flooding. Specific background research on the amount of water mung beans need would have prevented this happening. Thus the results above are not an accurate representation of the effect of flooding on mung beans.
Conclusion
The results did not support the hypothesis. The germination data showed an upward trend over the course of the experiment. The quickest rate of germination was Dish 5 (25 ml) as it only took one day to germinate and all six seeds had germinated.
