BREAKING DORMANCY FAVÃO FOR USE OF THE RECOVERY OF DEGRADED AREAS IN MARABÁ-PA

Abstract

ABSTRACT: The recovery of degraded areas becomes an alternative for the environment and society. Marabá-PA in areas where activities clay extraction is conducted is degradation. O bean (Parkia multijuga Beth) is a legume and is a common occurrence in the Amazon region. The aim of this study was to determine the best method of breaking dormancy for Fava, noting the rate germination. The experiment in the greenhouse was a factorial in completely randomized design (CRD), containing a plant species, a type of substrate, Three methods of breaking dormancy which consisted of a control (without breaking dormancy) (TR1), mechanical scarification (TR2) and Soaking in H2SO4 for 16 minutes (TR3), where it used to 40 repetitions, totaling 120 pots (1x1x3x40). For the germination data was used three simple rule using the value of the quantity of seeds germinated with the amount of seeds sown. The data were analyzed and subjected to the tests mean and variance of Tukey at 5% probability, using methods described in the software SISVAR. The method to overcome dormancy of bean was the most efficient chiseling.   KEY-WORDS: germination, Parkia multijuga, rehabilitation.
