Abstract Highlights

Avocado plants of cv. Hass were used to study the behavior of some physiological and biochemical aspects under the condition of drought and irrigation. It was found that the photosynthesis, stomatal conductance, transpiration and water use efficiency were highly affected by water deficit and in re-watering recovery at permanent wilting point (PWP) and did not recover after 24 hours. The water, osmotic and tugor potentials, as well as the relative water content were similar under drought and irrigation, thus apparently osmotic adjustment was occurring. The proline content was significantly higher in PWP with respect to the control. The abscisic acid content was also higher in drought at PWP and was double that of the irrigate control.
