- For Calamagrostis, Rhododendron and Vaccinium the data at the two sites in the nitrate gradient (b-2 with b-3, b-2 with b-4 and b-3 with b-4, respectively) are compared. All numbers are means of 15 measurements. Colored squares identify the plants for which the results are statistically different (p < 0.01) at the two sites
- athe initial velocity has been calculated as Vinit = FV150 μsec/0.15
