Résumé

Plant responses to reduced water availability are complex because they affect several processes of plant metabolism. The experiment aimed to quantify morphometry and stomatal conductance as a function of irrigation frequency at the end of production cycle of pau-marfim and guajuvira seedlings. The experiment was conducted in a shade house with the imposition of daily irrigation for 30 days, irrigation every other day for 30 days, irrigation every other day for 15 days and every four days for 15 days, and watering every other day for seven days and every four days for 23 days. The results indicated a decrease in stomatal conductance with an increase in the interval between daily irrigations in seedlings of pau-marfim and guajuvira while morphometric variables did not show sensitivity to the treatments.
