Diagram of the experimental design. The effects of summer temperatures and the timing of heat shock were analyzed in a factorial experiment. Seeds were exposed to a heat shock (100 °C for 10 min) before, after, and before + after a month of exposure to summer temperatures (50/20 °C) together with a control without heat shock. Additionally, a control without exposing seeds to summer temperatures was added for each treatment by repeating the experiment at the same time but under laboratory conditions (around 20 °C) instead of summer temperatures
