Is Tolerance the Capacity to Endure Shade?
Abstract:In 1917, the S.A.F. Committee on Terminology defined tolerance as the capacity of a species to endure shade. Proponents of the root competition theory have broadened the definition to include ability to withstand competition for soil moisture, soil nutrients, and other factors. The author presents evidence and arguments to show that tolerance of shade is not necessarily related to tolerance of low soil moisture, low nitrogen supply, low phosphate supply, and other environmental deficiencies. He, therefore, urges that shade tolerance be restricted to ability to survive in light of low intensity.
