Height (maximum stem height, centimeters), basal stem diam (basal stem diameter, millimeters), plant area (square centimeters), leaf, stem and shoot biomass (grams), Apr phen state (phenological state in April, see legend of Fig. 3)
^aP values for the control group correspond to the contrast to compare control mean with the average of all the other treatments means. n = 60 plants per treatment for height, basal stem diameter, and phenological stage in April and 21 plants per treatment for plant area, leaf, stem, and shoot biomass
