Abstract

The production and physiological seed quality are directly associated with a good availability of nutrients in the crop. Seed production in areas with zinc deficiency, can generate seeds with low content and concentration of this micronutrient, the logo may be less vigorous seedlings, which may reflect in low yield. In this context, this work aims to evaluate the influence of seed coating with zinc in oat seed physiological quality and initial growth of plants. The experimental design was completely randomized in a factorial 2 X 5, two products (Teprosyn ™ Zn and seed Quimifol 78 ®) and five doses (0, 100, 200, 300 and 400 of the product 100 ml kg-1 seed) with four replications. The treated seed physiological quality was evaluated by testing first germination, germination and accelerated aging. For the initial plant growth variables plant height, leaf area and dry weight of plants were evaluated, and with the data of leaf area and dry matter of the plants was calculated growth rates of culture (TCC), rate relative growth (RGR) and net assimilation rate (NAR) and measured in the same three periods (10, 20 and 30 DAE). The Teprosyn ™ Zn and seed Quimifol 78 ® products can be used as a seed treatment to doses of 100 and 200 mL 100 kg-1 seed respectively, without harming the seed quality. The Teprosyn Zn ™ product with 17 g L-1 of nitrogen and 600 g of zinc L-1, from the dose of 200 mL for 100 kg-1 seeds, 30 days after emergence, plant shows reduced growth and leaf area compared to maximum dose of technical efficiency.
