Abstract

This study aims to verify the efficiency of chemical scarification on breaking dormancy of Senna occidentalis seeds in different immersion times in order to answer the following question: are different times of chemical scarification in sulfuric acid capable of influencing the process of breaking dormancy of fedegoso seeds? The research was conducted in the seed laboratory of the Federal University of Espírito Santo, in the municipality of Jerônimo Monteiro - ES. The experiment was conducted in completely randomized design (CRD) with five treatments and four replications containing 25 seeds each repetition, being control, seeds immersed in sulfuric acid for sessions spaced in 15, 30, 45 and 60 minutes. Thus, we evaluated the germination percentage and the germination speed index, and may be concluded that there was a significant increase in seed germination subjected to chemical scarification increasing as a function of immersion time.
