Abstract: Abstract. The development of temporary water stress during the day-light hours, characterized by a decrease of the values of the water potential (Vjw) and increase of the values of water saturation deficit (AWsat) was found not only in the leaves of intact kale plants but also in cut leaves with their petioles immersed in water. These results indicate that the leaf resistance to water transport could not be supposed as negligible. The same decrease of water potential was accompanied with the higher increase of AWsat in cut leaves than in leaves in situ.
