Abstract

Coffee cultivation emerges as a more viable and commercially sustainable planting alternative for areas degraded by sugar cane monoculture. Therefore, studies with coffee cultivars seek for plants that are more adapted to the environmental of Brazilian northeast. Thus, it is possible to obtain a better performance in the water consumption and maintenance of the high productivity levels in the field. Regarding this, studies of the morphological characteristics and mechanisms of physiological response of the plant, which control the loss of water by the leaves, are of extreme importance. So, they allow the adaptive evaluation of the variety to the region of Zona da Mata of Pernambuco, aiming an better adequate use of the species under study. Therefore, this work, which was carried out in the Department of Nuclear Energy of the Universidade Federal de Pernambuco (UFPE) and in the Instituto Agronômico de Pernambucano (IPA) Experimental Unit, consisted of the characterization and morpho-anatomical analysis of Coffea canephora L. (Early Vitória variety 2 INCAPER). Then were performed the following procedure: selection of clones in the experimental field, collection of botanical material, characterization of hydraulic properties, hydraulic functionality and analysis of experimental data. In general, it was concluded that the clone of the early Vitória variety 2 did not show large phenotypic variations. Indicating that these plants are exhibiting the same adaptive response in the Brazilian environment.
