Figure 5
A-PPFD curves, net photosynthetic CO2 assimilation rate (A) as a function of photosynthetic photon flux density (PPFD) of three-year-old ‘Haas’ avocado seedling leaves before (left) and after (right) short-term low temperature treatments. All symbols present the mean responses of biological replications (n = 6 and 3 for before and after treatments, respectively). Error bars show the standard errors of the means for A. Closed triangles, squares, and circles after treatments indicate the responses of the samples after treated with 1 h 1, − 2, and − 5 °C, respectively.
