Figure 4
A–Ci curves, light-saturated net photosynthetic CO2 assimilation rate (A) as a function of intercellular CO2 concentration (Ci) of three-year-old ‘Hass’ 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 (vertical) and Ci (horizontal). Closed triangles, squares, and circles indicate the responses of the samples after treated with 1 h 1, − 2, and − 5 °C, respectively.
