Temperatures producing heat injury in leaves of 30 species (mainly vegetables and tree fruits) were measured by following heat-induced changes in fluorescence of the leaf chlorophyll. Chlorophyll fluorescence began to increase between 30 and 40 deg in the alpine plant Plantago glacialis, at 51.2 deg in lettuce and 57.6 deg in pawpaw. The mean temperatures for the initial rise in fluorescence and for peak fluorescence occurred at a lower temperature in the alpine plants studied than in the temperate plants and at a higher temperature in the tropical plants, demonstrating a relationship between heat resistance and the temperature of the environment in which the plants evolved...
