Radish seed with longer hours of treatment in water germinate more
The objective for this experimentation was to determine the effect that water had on radish seed germination in different hours of being exposed in water. Seed germination is an important aspect of life because by those seeds that germinate become fruits and vegetables to consume. Therefore, it is necessary to know the appropriate environmental conditions that a seed needs to germinate. Different types of seeds have their own requirements of water concentration in order to germinate. Although water is necessary for germination of seeds, too much water or too little water can cause the seed not germinate. In the study, A model effects of water stress

In another study, Effect of water potential on seed germination, Steve Oberbauer and Philip C. Miller conducted an experiment to see the germination response of selected species to different soil water potentials (Oberbauer and Miller). In the experiment they had 25 seeds of each different species for their study. The seeds were in a container with water and kept at a constant temperature (Oberbauer and Miller). For this particular experiment germination for the seeds was described by having the first appearance of green tissue (Oberbauer and Miller). The overall results for the experiment concluded germination was delayed in those species with low water potentials (Oberbauer and Miller). Consequently,in our experiment we are looking if the amount of time the seeds spends in water tend to affect the germination process. Our definition of germination for the purpose of the experiment is when the seed coat starts to crack open. As a group we hypothesize that, seeds that spend the most hours in water are going to germinate more compared to those that spend the least amount in water. If the radish seed …show more content…
Each treatment had a total of 19 radish seeds and each was placed in their own salsa cup. The first treatment the radishes had no water. The second treatment the radishes were placed in water for 6 hours. The third treatment the radishes were places for 12 hours. The fourth treatment the radishes were placed for 24 hours. The fifth treatment were placed for 36 hours. The sixth treatment were placed for 48 hours. The seventh treatment were placed for 60 hours. The last treatment was completely submerged. All of the salsa cups were marked with their corresponding treatment. Once all the radishes were placed in their corresponding salsa cups water was added. The water for the treatments came from tap water from our lab room. Once all the salsa cups were properly prepared with the radish seed they were placed in the incubator to maintain a constant temperature. The experiment was conducted for a week where we looked at the different hour treatments to see if the seed radishes germinated. For each treatment there were 2 to 3 students who volunteer their time to check the rate of germination. At the end of the experiment we calculated the total number of the seeds that germinated for each particular treatment. Furthermore, after obtaining our result we use the chi square for the statistical analyses. With the chi square we can obtain a confidence values and use the degree of freedom to analyzed our result. With the chi square we are
