- Abstract
In Brazil the papaya in the different areas where it is produced has great socioeconomic importance, specifically in the Northeast region. However, in this region, most reservoirs contain water with high salt content. In this way, the objective of this work was to evaluate the growth and partition of dry phytomass of UENF/Caliman 01 papaya seedlings irrigated with saline water. The experiment was conducted in a greenhouse of the State University of Paraíba, located in the city of Catolé do Rocha, coordinated 06°21'S e 37°48'W. The experimental design was completely randomized, consisting of five treatments: water salinity (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) with four replicates. The increase of water salinity reduced plant height, stem diameter, leaf area and dry matter of leaves, stem and root of UENF/Caliman 01 papaya, at 60 days after seeding. The stem diameter of papaya UENF/Caliman 01 is a characteristic little sensitive to water salinity, while the leaf area and leaf dry weight are very sensitive.
