Abstract

The Bugio’s tail (Dalbergia ecastophyllum) belonging to the Fabaceae family, present in the most diverse forms of relief, soil and vegetation, is a species that can withstand adverse and stressful situations, vigorously under high salinity and flood conditions, commonly found in estuaries, mangroves and coastal dunes. The objective of this study was to evaluate the initial growth of the species in the Paraíba hinterland under saline stress. The experiment was conducted in a greenhouse at the Center for Agri-Food Science and Technology, Federal University of Campina Grande, Campus Pombal. The experimental design was a randomized complete block design (DBC) with six treatments and three replications obtained by the addition of NaCl. The water used was supplied to the population of the city of Pombal, where the catchment is made in the Piancó River, and has an electrical conductivity of 0.3 dS m-1 (T1), so that the solutions were calibrated for the respective electrical conductivity of irrigation water applied after 30 days of sowing: T1 = 0.3; T2 = 1.5; T3 = 3.0; T4 = 4.5; T5 = 6.0 dS m -1. The variables evaluated were after the beginning of the treatments, namely stem diameter, plant height, leaf number and leaf area. Significant differences were observed between the saline doses applied for the study variables, stem diameter at 45 and 60 days of treatment, plant height at 30, 45 and 60 days, and leaf area at 45 and 60 days after treatment. beginning of treatment, with decreasing linear effect for all. Irrigation with different saline levels did not influence the initial development of D. ecastophyllum for the parameters stem diameter up to 30 days, number of leaves up to 60 days, plant height up to 15 days, and leaf area up to 45 days.
