Plants of 5 species were acclimated for periods of not less than 3 weeks in a desert and subalpine environment. Subsequent measurements of photosynthesis over a range of temperatures indicated both rate modifications and shifts in temperatures of optimal photosynthesis. Plants of all species acclimated in the coldest environment were more efficient in terms of percentage of maximum photosynthetic activity at colder temperatures. Conversely, plants acclimated in the desert environment were more efficient at warmer temperatures.
