Experimental design applied on 12 angiosperm and conifer species. The first acclimation period was followed by a light manipulation phase, and a drought experiment until full mortality was observed. Five harvests were carried out to gather NSC data from three different organs. The number of harvested plants per species and per treatment are indicated inside the lower boxes. Additional measurements of predawn (ΨPD) and midday (ΨMD) water potentials along with visual assessments of mortality percentages based on leaf coloration were carried out weekly during the drought experiment
