  1. How Does the Number of Seeds Planted Together Affect the Growth of Wisconsin Fast Plants? By Roy, Andrew, Cathy and Yousra

  2. How the Experiment was Conducted - Planted Seeds in cells. In experimental 2 seeds in cell 1, 4 in cell 2, 6 in cell 3, 8 in cell 4. In controlled 3 seeds in each cell in the control quad. -Placed fertilizer pellets in each cell. - Put water in a container and placed a piece of felt to absorb water on top of the container. Then placed the quads on top of the container. -We observed the plants for a few days and sometimes measured them. -Pollinated the plants and eventually opened the seed pods and counted pods and seeds.

  3. Control Variables • Height of light above plants (unknown) • Amount of water given to plants (tank under plants which is soaked up by roots through felt) • Amount and type of soil (unknown) • Amount and type of fertilizer (3 each) • Amount of light (40 watts for 24 hours/day) • Size of quad cells (1 sq. cm)

  4. Growth of Wisconsin Fast Plants Days 13-15 All plants increased in height by the 15th day. Days 15-21 The largest increase in the plants height was during these 6 days. Days 21-24 In between day 21 and 24, the c.g. plants were still growing but the e.g. had slowed down their growth. Days 24-28 During these days, the growth of all the plants had slowed down to a very small minimum.

  5. Average Number of Pods Per Plant

  6. Average Number of Seeds Per Pod

  7. Sources of Error • Temperature during growth was low • Hereditary problems • Type of light • Plant seeds were old • Control Group was shifted • Some plants were transplanted

  8. Conclusions The number of seeds effected the growth and development of the plant in many ways. The first was that the plants had to share the water. Another way that having more then a single cell per cell was that the plants had to compete for space. Also the plants had to share a normal amount of light for one plant. Among two to eight plants.

  9. Recommendations To Improve Experiment • To do experiment in the spring or early fall so that it is not so cold. • Have same kind of light for both experimental and control group. • Do not do over a long break. • Don’t transplant because it might be a failure.
