Abstract
A comprehensive study was performed to assess the effect of a drought cycle on the key physiological processes of Highbush blueberry.
Water potential, embolism, transpiration (leaf and plant), stomatal conductance were surveyed.
The major conclusions of this work are : (i) blueberry is highly sensitive to water deficit (ie. stomatal closure and decrease of transpiration occurred rapidly as water potential decreased) ; (ii) the rapid decrease of stomatal conductance efficiently restricts water loss and thus water potential decrease, preventing embolism occurrence ; (iii) blueberry exhibits a good recovering capacity after rehydration.
