From: Cold-acclimation limits low temperature induced photoinhibition by promoting a higher photochemical quantum yield and a more effective PSII restoration in darkness in the Antarctic rather than the Andean ecotype of Colobanthus quitensis Kunt Bartl (Cariophyllaceae)

Figure 2

Effect of cold acclimation on photochemical fluorescence parameters under PhT and dark recovery in plants of both ecotypes of C. quitensis . 1-qL (A) is the proportion QA in the reduced state, and ΦPSII (B) is quantum yield of PSII. Measurements were done at 4°C using an actinic light of 900 μmoles of photons m-2 s-1. Results were calculated from five independent measurements of different plants. Bars show mean values ± SE. Different letters represent significant differences between growing conditions, ecotypes and treatment P<0.05 using three-way ANOVA.
