Effect of pH on Green Pea Germination Objective: To determine how pH affects the germination of green peas and to examine the degree of germination within each pH level. We will do this by using various buffer solutions (along with distilled water) to grow green peas. Hypothesis: We expected that the group of peas that encountered a pH of 7 to have the most and highest degree of germination. Materials: tap water buffer solutions pH 3,5, 7, 1 distilled water 50 greens peas trays paper towels beakers Procedure:
Wrap 25 peas (25 peas = 1 group) in paper towels.
Place each group in 2. Pour 10 mL of tap water and 30 mL of distilled water or buffer solution onto each group of peas 3. 4. Add tap water accordingly to keep peas moist After one week, add another 20mL of distilled water or buffer solution onto each group of peas. 5. Observe amount of germination and degree of germination (length of the shoots) PH3 PH5 Distilled Water PH7 PH9 PHII Number Germinated 17 24 Number not Germinated Number of peas with shoots that were at least 1 inch long 14
