Controle de patógenos em sementes de espécies alimentícias nativas do cerrado.

Abstract

Pathogen control in the seeds of native cerrado species is an essential mechanism for seedling production. These seedlings play an extremely important role in the preservation of the native vegetation of the country, both in the context of ecosystem regeneration and in the valorization of native products that have considerable market potential to boost local development. Therefore, the main objective of the manuscript is to evaluate the efficiency of electromagnetic microwaves on pathogens and on the sanitary quality of Buriti (Mauritia flexuosa L. f.), Pequi (Caryocar brasiliense Camb.), Cagaita (Eugenia dysenterica DC.), Marolo (Annona crassiflora Mart) native Cerrado food species. Specifically, [1] to identify and quantify developed fungi considering incidence calculation, [2] to identify potentially pathogenic fungal species. The research was developed in partnership with the Seed Analysis Laboratory of the Alto Parnaíba Cerrado Campus of the State University of Piauí. Thus, this research is part of an umbrella project, developed in partnership between the aforementioned Higher Education Institution and the Federal University of Campina Grande. The treatments were exposed to exposure times of 0.10, 20, 30, 40, 50, 60, 70, 80 and 90 seconds in microwaves at a power of 900w and a frequency of 2.45 GHz. Twenty seeds were used per treatment, distributed in 4 repetitions of 5 seeds; since forest seed production is much lower compared to grain production. The seeds were incubated at room temperature for a period of 7 to 14 days. The data was submitted to variance analysis and the fungi found were analyzed.
