When trying to grow plants you must take into account the different variables that may help or hurt your plants. For instance the amount of light, water and food it gets. In this lab we wanted to see the different effects certain things would have on growing plants. We did three different experiments. The first one was a light vs. dark experiment. To see if a plant would grow better in light vs. a dark area. This has to do with phototropism which is the response of a plant to light and etiolation which is when a plant is grown in a dark place and grows spindly and tall and white. My hypothesis was if we put one in a dark place and one in a light place than the one that had the light would grow. I didn’t believe the plant grown in the dark would grow. The next experiment we did was testing the apical dominance of the apical bud. This is a little bud that has an auxin that causes the lateral buds to become dormant. We wanted to find out what would happen if we removed it. My hypothesis for this one was that without these apical buds the lateral buds would grow out and be bushy. The third and final experiment that we did was the effects of gibberellic acid on dwarf pea plants. This acid is used t
The last experiment done was the stimulation of gibberellic acid on dwarf pea plants. First there were three dwarf pea plants planted and labeled one pot was the control and the other was the gibberellic acid. There were two plants in one pot and one in the other. Then the acid was placed on the surface of the plant and it was done again in the second week. Then observed and recorded for three weeks.
As you look at this table you can see how the plants with the lanolin and the apical bud cut of had the most lateral bud growth. The ones that had the auxin replaced stayed very small and not bushed out.
