Q32 - Thermal Acclimation and Photosynthesis in Arctic Plants
Refer to the question paper for figures and tables.
a. Acclimation to higher temperature resulted in higher rate of net photosynthesis.
b. There is a linear increase in rate of dark respiration only above 10 C in S. cernua grown at lower temperature.
c. Optimum temperature of gross photosynthesis increased to 12 C post acclimation.
d. The difference between temperature optima of net and gross photosynthesis is due to dark respiration.
