During the course of the experiment two different plant characteristics were measured. The first was the cotyledon stage of Arabidopsis growth. This was defined as group A and it is characterised by two cotyledons emerging from the radicle above the soil. Group B was then characterised as the next stage in the growth/development process of Arabidopsis . Group B is characterised by two cotyledons as in group A but it also contains true leaves. In other words seedlings with two ‘leaves' (cotyledons) were classed as A and those that had 4 leaves (2 cotyledons and 2 true leaves) were classed as B. The results were measured daily at approximately 11 am every day over the course of 14 days. There was no need to carry the experiment further than this as it would just be measuring their rate of growth as opposed to their rates of germination. There were 2 main aspects of seedling growth that was being measured. The first was the time it took for the radicle to penetrate the soil. The second was the rate at which the seedlings developed from group A to group B. The reason for this was that it was important to measure whether stratification would affect radicle emergence or the rate of growth of the seedling, i.e. time it took for the seedling to grow from group A to group B in comparison to the control.
