  1. Heat exposure: ex situ using detached leaves 1 following Buchner and Neuner (2001), 2 in water baths, in situ, using the Heat Tolerance Testing System HTTS. Heat exposure took place in dark - mode (D) or in light - mode (L). Viability assessment: visual assessment by computer based measurement (VAC) of leaf damage, by estimating leaf damage (VEM), by electrolyte leakage test (ELT) and by the chlorophyll fluorescence method (CHFL).
