Abstract
Seeds are considered to have high vigor as long as they are handled in the right way, always taking as fundamentals, in the pillars of their quality, which are: physical, physiological, genetic and sanitary. A total of 200 seeds were used for 8 treatments of the same variety conducted in the seed laboratory of the INSTITUTO TOCANTINENSE PRESIDENTE ANTÔNIO CARLOS (ITPAC-PORTO), which were subjected to conditions of two temperatures: 10°C and 25°C, under 4 situations of osmotic potentials On substrates: 1.5, 2.0, 2.5 and 3.0 ml. An evaluation was carried out at 5, 8 and 20 days after assembly, using seedling emergence and development as a parameter. The samples were analyzed based on the RAS (RULES FOR SEED ANALYSIS), i.e., they were considered germinated when they showed the development of a normal seedling. The data will be submitted to analysis of variance (ANOVA) and Tukey's test in the Sisvar software. The results allowed us to visualize the excellent germination and growths of the seedlings when using the temperature of 25°C and wetting of 2.5 ml in the substrate. Germination is impacted when the low availability of water in the substrates, as well as milder temperatures, influences the speed of development of meristematic tissues.
