Germination behavior of Albizia Lebbeck (L.) Benth in weakly saline soils in Río Cauto

Abstract

The present study aimed to evaluate the behavior of nursery germination of Albizia lebbeck (L) Benth weakly saline soils in the municipality of Río Cauto, Granma Province. The research was conducted in the period from March to June 2012 in the forest nursery Cauto Embarcadero belonging to Río Cauto silvicultural UEB. To determine the germination of the seeds, the germination test performed which consisted in putting to germinate 25 seeds per treatment at 5 for plates with filter paper petris as Treatment 1: added 10 mL of chloride solution sodium (NaCl), adjusted to an electric conductivity of 2 dS m-1 and as treatment 2: a sample pattern with deionized water having an electrical conductivity of 0, 02 dS.m-1 counts were performed daily until the 30 days. The electrical conductivity was measured with the brand portable conductivity meter HANNA HI 9033 multi-range model. Four treatments were studied: a standard with no saline growing medium and three growing media evaluated as weakly saline in a range of 1 to 2 dS m-1. Statistical analysis showed that there were no significant differences between treatments.
