Figure 1

Time courses of leaf temperature during and after 2 h sudden heat shock (SHS) cycles across both CO2 treatments (380 μmol mol−1, 560 μmol mol−1). Grey area represents the period during 2 h SHS at 45–46°C. Arrows represent time points that gas exchange data and leaf sampling measured. In open top chambers, gas exchange measurements prior to SHS started from 9:30am–10:00 am, while SHS was from 10:00 am–12:00 pm. After SHS at 2 h and 4 h, the local time was 14:00 pm and 16:00 pm, respectively. Numbers of replications, n = 5–13. Pairwise t-test was used to compare significant difference of leaf temperature between SHS and nonheated treatments. Symbol “***” represents P value < 0.001.
