DescriptionSeveral species of higher plants and mushrooms have been surveyed growing under the canopy of old stands of hemlock surrounding Clear Lake near Minden, Ontario. Some of the hemlock seedlings growing on fallen trunks together with debris in which they were growing were brought to a greenhouse in pots, and some of them were transferred into sandy soil. The conditions of growth involved a gradient of shading. As an analysis of the debris revealed a low pH, the soil in all pots was kept at a pH of 5.5. The best growing seedlings were in the most shaded areas in pots filled with plant debris and the worst growth was in sandy soil in full sunlight. We have measured the concentration of phenolic compounds, which was found to be highest in dying plants in sandy soils in full sunlight, and lowest in shaded areas in pots filled with debris.
