Fig. 3From: Differences in growth-economics of fast vs. slow growing grass species in response to temperature and nitrogen limitation individually, and in combinationOptimal growth temperature. Displayed is a ratio between the optimal temperature for photosynthesis (Topt) and the growth temperature during the experiment. These values are related to the growth temperature to visualize deviations and acclimation. A ratio of one indicates that the optimal temperature matches the growth temperature, values above one indicate that the optimal temperature was higher than the growth temperature and vice versaBack to article page
