Conclusion: If two of the same types of seeds are different sizes then the larger seed should germinate faster because it has more nutrients. All but 1 out of 9, 3 mm Rhaphanus sativum germinated. They germinated in about 2 ½ days. The 1. 5 mm Rhaphanus sativum germinated slower, but only by about 12 hours. All 9 of those seeds germinated. The 3 mm seeds grew an average of 2. 5 mm long and average mass of about 0. 155 grams. The 1. 5 mm seeds grew about 1. 2 cm long and massed out at a average of 0. 111 grams. So they were more dense for their size. Problems accrued: The biggest problem we ran into was not having enough water. We had to keep a soaked paper two on top of the dishes to keep moisture on the seeds. Procedure: 1) Get all materials needed to conduct the experiment. 2) Get filter disk and measure and draw a line 6 cm up from. Then repeat this two more times. 3) Place filter disk in the petrie dishes cap. 4) Place three large 3 mm Rhaphanus sativum and three 1. 5 mm smaller Phaphanus sativum seed on each drawn line. 5) Use the pipette to withdraw some of the RODI water and place evenly threw out the filter disk until all wet. 6) Place the lid on the petrie dish and wait 21 hours then collect data. 7) Repeat this process three other times Why we did this project: Our group did this project because we wanted to see which seed would germinate faster 3 mm seeds or 1. 5 mm seeds. Over all we figured out that the larger seeds germinate faster also they have a larger mass and are longer. By: The Four Macho Nachos Kayla, Willis, April, Taylor Materials needed: 3 Petrie dishes, 3 filter disks, 1 metric ruler, 1 pipette, RODI water, 9 small and 9 larger Rhaphanus sativum. People it reflects on: Now farmers and florists can know that if your buying the same type of seeds that they need to buy the larger seeds if they want quicker and more efficient germination.
