The Effects of Sildenafil on Plant Growth using Brassica rapa seeds

Introduction: Plant growth and development are affected by an overwhelming amount of factors in their environment but all these factors can be manipulated and given the perfect conditions the plant can grow to reach its peak size and potential. Rate of plant growth intrigued my fellow group members and I so it was decided that growth in mm as well as germination of the seed itself would be studied. With research being conducted into what we could change about the plants environment to change the rate of growth it was found that the simplest thing to manipulate would be the water the plant absorbed. Experiments such as this had been conducted before but most focused on adding
Rise and dry mortar and pestle. Second obtain the remaining two Viagra pills and repeat the first step emptying the mortar into a new quad. Rinse and dry mortar and pestle. Next add two hundred ml of water to each of the three quads, making one the control. Stir each with the scoopula for approximately one minute. After this, place the circular filter paper into each petri dish adding three seeds near the top of each dish. Using one quad for each petri dish only pour a small amount into each dish. This should be enough to dampen the filter paper but not completely soak it. Next, you are going to want to place the lid on each petri dish and using one piece of tape, tape the dish to keep it shut. Then pick up each petri dish and place them into the respective quad that you poured on the seeds earlier. Using the tape again you are going to tape the quads as to hold the petri dishes upright so that the liquid can flow into them appropriately. Next put all the dishes under the same light source so that growth can be stimulated. Finally leave the dish for two weeks and allow the seeds to germinate and grow coming back for measurements. After two weeks the length of each plant will be measured and recorded in
If the hypothesis was supported then there would have been a more uniform growth rate with the control growing the least. Also, it is important to note that with the data collected figure 3 it is noted that the roots of the control plant are a great deal longer than either roots exposed to Viagra. This could be due to the absorption rate of water in the plant, the control needing more to carry out processes while the ones containing viagra needed less. Also the plant that grew the tallest had the shortest roots present (figure 1). If another experiment were to be done root length should also be taken into
