Efficiency of cinnamon extract (Cinnamomum zeylanicum Blume) in the treatment of seeds of braúna (Schinopsis brasiliensis Engl.)

ABTRACT: For decades, chemical products have shown efficiency in inhibiting pathogens associated with forest seeds, but due to the high cost and environmental impact caused by it, research to find more viable and sustainable alternatives has been Held. The objective of this work was to evaluate the efficiency of Cinnamomum zeylanicum Blume extract in the treatment of seeds of Schinopsis brasiliensis Engl. And to indicate the use of plant extracts as an alternative for the control of pathogens associated with Forest seeds. For the sanity test, 500 seeds collected in 2010 and 500 seeds collected in the year 2014 submitted to treatments with cinnamon extract were used in the following concentrations: T1: solution containing 100% sterile water (control); T2: Solution containing 25% of cinnamon extract and 75% of sterile water; T3: Solution containing 50% cinnamon extract and 50% of sterile water; T4: Solution containing 75% of cinnamon extract and 25% of sterile water; T5: Solution containing 100% of cinnamon extract. The health test lasted 10 days and after this period, the pathogen was evaluated, associated with the seeds of S. Brasiliensis, through the observations of the fungal structures through a stereoscopic and optic microscope, and the help of the literature Specialized. The means were analyzed by the Tukey test at the level of 5% probability and the percentage values for the purposes of statistical analysis were transformed into arcsen√x/100.The treatment with solution containing 100% of cinnamon extract presented as the most efficient being the most suitable for the inhibition of pathogens associated with the forest seeds. Considering the results, we recommend the advancement of researches around the use of plant extracts as a solution for the treatment of forest seeds so that it becomes a viable alternative in the forestry sector.
