Abstract
In the story of the seed, we decided to test six broccoli plants, three of which were in front of the fan to test how plants germinated in the wind factors of real life. We used materials including soil, plant containers, water, a fan, and aqua light meter and the broccoli seeds, using 75 milliliters of water on each plant. We watered them equally every other day and watched how the factors impacted the plants. In general, the control group was healthier, with moister soil, longer stems, and larger average leaf area. These facts show that if we keep wind off of plants then they will germinate more. In conclusion, the amount of wind on a plant does affect its growth negatively.
Introduction
Our project is all about the species of plant brassica oleracea. This includes broccoli and many other plants. We made observation of plants, which we created a question out of. We noted that wind factors may affect the growth of plants and how well they produce and thrive. We tested this by our fan to plant experiment. We placed three broccoli plants in front of a fan, and three away from the fan. By the first day, we had already been noticing signs of dehydration in the plants that were in front of the fan. When we had tested their moisture level, they seemed to have extremely low to no moisture at all. Our group also saw that the sprouts were less populated in the plants that were in front of the fan in comparison to the ones that were not in front of the fan. The plant tips were also yellowing and turning dry and flaky.
Materials and Methods
In our project, the materials we used were plant containers, soil, water, a fan, aqua light meter, and most importantly broccoli seeds. We placed 3 of the broccoli plants in front of the fan and three separate from the fan. We gave each plant 75 milliliters of water.
Experimental Procedure
We used plant containers, broccoli seeds, water, natural organic soil with fertilizer. Specifically speaking, we used 6 plastic plant containers and put 4 seeds in each. We watered it every other day with 75mL. After that we measured the stems every time we checked in which was every other day, and collected other data.
- Fill plant container with soil
- plant 4 seeds in the container
- water it every other day with 75mL
- Collect data every other day
Results
There were a lot more sprouts in the control group than in the experimental group. Some of the plants in the experimental group were drooping. The soil was also much drier in the experimental group, as shown in the graph above.
Discussion
In this project we calculated the results of how wind will affect are plant. We have been showed that the plant with no wind grow longer stems and bigger leafs. We hypothesized that if the amount of wind on a plant affects its germination rate, then the plants with less wind on them will have a higher germination rate. Are team got the expected results that we wanted. Some thing we did that we will change in the further is, put the same number of seeds in each pot, we will add the same amount of water in each pot daily, and have more than just high wind and low wind. We had some limitations to our project like we did not have enough plants to get complete results. Despite all that we had a number of strengths like, we had no wind gong to the control group and calculated the data for every day but weekends. These results can be used in the real world, we can make it so plants don't have wind and germinate more. This is very significant because we could have more plants and the farms could get more money to help himself of his family.
Conclusion
We now know that constant wind does have an adverse effect on the growth of brassica oleracea plants, most likely because it dries out the soil of these plants.
