herbaceous plants showed greater temperature homeostasis
of photosynthesis (i.e., the photosynthetic rate at highgrowth
temperature divided by that at low-growth temperature
was close to 1.0) than deciduous woody plants and
annual herbaceous plants, indicating that photosynthetic
acclimation would be particularly important in perennial,
long-lived species that would experience a rise in growing
season temperatures over their lifespan. Interestingly,
across growth temperatures, the extent of temperature
homeostasis of photosynthesis was maintained irrespective
of the extent of the change in the optimum temperature for
photosynthesis (Topt), indicating that some plants achieve
