Schematic representation of the cycles of dehydration and re-watering. Each drought cycle consisted of a dehydration phase followed by a recovery period. Dehydration was imposed by suspending irrigation until the ASWC reached approximately 10% (red dashed line) and the plants were kept at this soil water level for 2 days, after which the pots were re-watered until the ASWC was 70%. The plants were then maintained for 2 days
