Viability of white oat seeds on different substrates and temperatures

Abstract

White oats are an annual winter grass used extensively in the southern region of Brazil, both in the form of grazing and in the form of grains for animal feed. The objective of the present work was to evaluate the germination of seeds of white oats (A. sativa L.) on different substrates and at different temperatures. The same was done in the laboratory of Plant Physiology of the Universidade Tecnológica Federal do Paraná, Campus Dois Vizinhos. The seeds used in this experiment were obtaind in local shop of Dois Vizinhos, Paraná State, Brazil. The experiment was installed with a completely randomized design with factorial 4 X 5 (substrate type X temperature) with 4 replicates, using 100 seeds per experimental unit. Afterwards, they were classified and separated into four lots, and put to germinated in paper, sand paper and vermiculite, which were placed inside gerbox boxes. The seeds were then separated into five sub-lots, the temperature being the temperature at which the seeds were placed for germination, which were at temperatures of 5°C, 15°C, 25°C, 35°C, and alternating from 5°C to 25°C. It is recommended for the germ processes of white oat seed substrate between paper or paper at 25°C temperature.
