Unformatted text preview: EFFECT OF DENSITY ON PLANT GROWTH Organism: Brassica napus L. (Canola) Day planted: December 3, 2009 Date of measures: February 4, 2010 Age: 61 Days Size of Flats: 325cm 2 Hypothesis : At higher densities plant growth will be decreased due to increased competition for resources (ie. Water, nutrients, light) Null Hypothesis: There will be no effect on plant growth when there is a higher density of plants (Expand on the hypothesis and null hypothesis later) We need to decide what measures we are going to do tomorrow. this is the list of them: • Leaf area per plant* • Dry weight of stems and leaves separately* • Number of leaves • Thickness of stem • Weight of seeds • Number of flowers • Number of seeds • Number of siliques • Height Points to consider in preparation for poster and oral presentations: 1) You will measure plant production at the three densities in terms of biomass and/or seed production. Results can be looked at in terms of production per unit area or perseed production....
