Manejo de irrigação em diferentes clones de eucalipto

Abstract

This study addresses irrigation management in different eucalyptus clones, which is crucial for the expansion of planted forests in Brazil. With a focus on seedling survival, the experiment aimed to assess the performance of clones under different irrigation regimes, emphasizing the resistance of clones in establishing eucalyptus forests. Conducted at the Federal University of Mato Grosso do Sul, Chapadão do Sul campus - MS, the experiment took place in a greenhouse with the planting of eucalyptus seedlings in 10-liter pots, applying different irrigation volumes at varying intervals. The study revealed distinct responses regarding survival and physiological characteristics of the clones, including photosynthesis, stomatal conductance, transpiration, and water use efficiency. The results highlight the importance of appropriate clone selection and irrigation strategies in the initial stage of crop establishment, contributing to more sustainable practices in eucalyptus production. This study provides technical information for selecting clones adapted to different environmental conditions, aligning with the principles of responsible management and efficient use of natural resources through optimal irrigation treatment.
