Wheat (Triticum aestivum), black oats (Avena strigosa) and canola (Brassica napus) are recognized worldwide as sources of oil, flour and fodder, widely used in food and feed. Being that to reach good yields it is necessary to use seeds with quality. Seed treatment is an efficient practice in the control of pathogens, inoculation and fertilization, mainly with micronutrients. The objective was to evaluate the physiological quality of seeds of three winter crops, submitted to the treatment of seeds with zinc application. The study was conducted in the municipality of Frederico Westphalen in the year 2016, in the seed laboratory linked to the Federal University of Santa Maria campus of Frederico Westphalen. The experimental design was a randomized complete block design, in which the following variables were evaluated in the first stage: first count, final germination, dead seeds, hard seeds and abnormal seeds; and in the second stage: emergence speed index, root growth, shoot growth, root dry mass and shoot dry mass. The treatment of seeds with zinc positively influenced all variables evaluated for wheat, increasing the rate of emergence speed, root growth, shoot growth, dry mass of radicle and shoot mass of wheat, however In general, it interferes negatively in the growth and establishment characteristics of the oat crop.
