The effects of stress on biomass, soluble sugar concentrations and VA mycorrhizal colonization in sugar maple seedlings (Acer saccharum Marsh.)
Increasing ozone levels (0, 50, 100, 150, 200, 300 ppb) coupled with 80% shading and 50% defoliation were examined for two year-old sugar maple seedlings for one growing season (June-September). Biomass, soluble root carbohydrates and mycorrhizal colonization progressively decreased with increasing...
