Abstract

To make the tree cultivation for commercial purposes less vulnerable to inclement environment conditions in Goiás state, Brazil, it is necessary to spread other fast-growing species with timber potential, such as the Brazilian fire tree [Schizolobium parahyba (Vell.) S. F. Blake], locally known as guapuruvu. However, little is known on the initial physiological performance of this species. The present work aimed to evaluate the initial development of the Brazilian fire tree in three different substrates, in order to determine the critical salinity levels for its cultivation. A completely randomized experimental design was carried out with 15 treatments and 7 replicates, in a 5x3 factorial arrangement corresponding to five salinity levels and three substrates. The following variables were evaluated: plant height, stem diameter, number of leaves, mass of fresh roots and shoots, and mass of dry roots and shoots. Data were subjected to the analysis of variance, as well as to the Tukey´s test and the regression analysis. The seedlings of Brazilian fire tree are sensitive to salinity, and may be classified as glycophytes because of the damage to growth that they undergo when subjected to irrigation water with electric conductivity lower than 1.5 dS m-1. The commercial substrate Terral Solo promotes more vigorous vegetative growth to the seedlings of the Brazilian fire tree substrates with sugarcane bagasse and sand.
