<br/><br/> <br/><br/>Abstract<br/><br/>In forest nurseries, one of the factors that change the growth and quality of seedlings is water supply, which has a<br/>direct influence on metabolic processes such as stomatal conductance and photochemical efficiency of photosystem II.<br/>This study aims to identify the influence of different watering regimes as well as the use of a water-retaining polymer<br/>on the initial growth and metabolic processes of Enterolobium contortisiliquum seedlings. The experimental design<br/>was in random blocks with a factorial scheme. Morphological attributes, as well as physiological and biochemical<br/>attributes were investigated. We verified that the performance of E. contortisiliquum seedlings depends on the<br/>watering regime provided to the plants; furthermore, up to 60 days after the application of the treatments, both the<br/>height and diameter of the collection and the leaf water potential were similar in the water regimes of 8 mm day-1<br/>and 12 mm day-1.<br/><br/>Keywords: abiotic stress, water potential, oxidative stress, antioxidant enzymes.
