Abstract

Knowledge about the physiological and sanitary characteristics of seeds is essential for seedling quality control. Thus, seed vigor and health tests are essential in the analysis of sample lots. This study aimed to verify the health and viability of Cenostigma tocantinum seeds collected in the municipality of Marabá-PA. Germination used the paper towel as substrate and incubation in BOD, and the viability was obtained by the tetrazolium method (0.1%). Seed health was assessed with and without 2% sodium hypochlorite disinfection. For each analysis, 200 seeds were used. The germination speed index (IVG), germination rate (%), average germination time (TMG), percentage of viable seeds and fungi incidence (%) were evaluated. The analyzes showed a germination rate of 85%, IVG of 6.49 hours and TMG of 2.85 days. Seed viability was 73%. The lot got 85% incidence of Penicillium sp., 46% for Aspergillus sp, 14% for Fusarium sp. and 16% of Rhizopus sp. The disinfection method was efficient in reducing the incidence of fungi.
