Drying and weighing were continued till constant weights obtained. Biovolume index, which is a non-destructive quick method to calculate the above-ground portion of the tree seedlings was calculated using the formula suggested by Hatchell (1985) i.e., Biovolume index = plant height (cm) x stem diameter (mm). Quality index, which is a measure to assess the quality of seedling based on the height, stem diameter and dry biomass was also calculated using the standard formula (Hatchell, 1985)
