🍇 From Journal of Plant Physiology: Grapevines adapt to drought type: under gradual stress, they “procrastinate,” delaying defense, while rapid drying triggers fast ABA-driven escape responses. (J. Orozco, M.A. Zwieniecki)

Fig. 1. – Scheme of the experimental setup. Gradual reduction of water provided under progressive drought (PD; water-green) treatment started on day 0. To achieve rapid drought (RD; grey), irrigation on the selected group of grapevines was interrupted from day 27; before that date, plants were watered up to pot capacity as controls. The yellow square represents control plants maintained at well-watered conditions throughout the whole duration of the experiment. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
