Abstract

The objective of this work was to analyze the influence of pH, amount of water on the substrate and salinity on the germination of Acacia mangium Willd seeds. Three experiments were performed. To verify the pH effect, five treatments corresponding to the levels (3.0, 5.0, 7.0, 9.0 and 11.0) were used. As for the amount of water in the substrate, four treatments were evaluated: T1-water quantity 1.5 times the substrate weight (~ 3 ml); T2 -amount of water 2.0 times the weight of the substrate (~ 4 ml); T3 -amount of water 2.5 times the weight of the substrate (~ 5 ml) and T4: amount of water 3.0 times the weight of the substrate (~6 ml). In the analysis of the effects of salinity on germination, three aqueous solutions were evaluated: potassium chloride (KCl), calcium chloride (CaCl2) and sodium chloride (NaCl) in 4 concentrations (25, 50, 75 and 100 million mM). All experiments were conducted on four replicates of 50 seeds for each treatment. The amount of water 2.5 times the weight of the substrate leads to higher germination of the acacia seeds, but with increasing salinity, there is a continuous decrease of germination, IVG, and initial growth, mainly with the salts KCl and CaCl2. The pH where the seeds had the best germination corresponded to pH 3.
