1. The Effects of Nutrient Level on B. rapa Growth Anna-Blaire Ozdil, Aubrey Todd, Cara Schwab, and Seth Davis Biology 9

2. Background Brassica rapa. Mustard seed Family: Brassicaeae Different family members: turnip and cabbage Some sent into outer space Seeds 40 days after planting

3. Background (continued) Only needs water, fertilizer, and light 150+ traits Cultivated in Europe for 4000 years Used as folk medicine “Fast” Plant

4. Purpose To determine the effects of nutrient level on plant growth in the rapid cycling Brassica rapa.

5. Hypothesis The nutrient level will greatly affect both the plant height and leaf size, making the plants with more nutrients taller and having larger leaves than their corresponding low nutrient plants.

6. IVDVEGCG Independent Variable: nutrient availability Dependant Variable: leaf area, height Constant: everything except nutrient level Experimental Group: 96 total plants in Biology 9

7. Apparatus largest true leaf Height to tallest apex multiplied the length and the width

8. Synopsis Make bottle growing system Take height measurements regularly Measure leaf area

12. Conclusion Plant Height was not changed significantly by nutrient level Higher nutrient level lead to bigger leaves

13. Future Questions Why does B. Rapa grow bigger leaves instead of growing taller? Where is the extra ATP generated going?
