Abstract: Abstraet. The water potential (Vw) and the water saturation deficit (A Wsat) in leaves of different insertion levels of potted kale plants were simultaneously measured. In non-wiltlng plants zJ Wsat gradually decreased and Vw slightly increased from the upper to the lower leaves. During the wilting of the plants induced by decreasing of soil moisture Vw practically decreased paralelly in all the loaves but the same decrease of Vw was connected with the lowest increase of A Wsat in upper loaves and the highest increase of A Wsat in lower leaves. Not only the values of ~Ow and A Wsat but also their relationship varied considerably with the leaf insertion levels.
