Sementes salvas e certificadas de aveia disponíveis na região de Pato Branco - PR

Abstract

Black oat (Avena strigosa Schreb) and white oat (Avena sativa L.) are important winter crops in the southern region of the country. However, many producers choose to use saved seeds, which do not always receive the necessary care in terms of cleaning, drying, and storaging; and therefore, sometimes do not have adequate quality compared to certified commercial seeds. This can result in production losses and consequently economic losses. Thereby, the objective of this study was to evaluate the physical and physiological quality of different lots and cultivars of saved and certified seeds of black and white oats in the Pato Branco region. The experiment was conducted at the Seed Analysis Didactic Laboratory of the Federal Technological University of Paraná, Pato Branco Campus, where nine cultivars/lots of seeds were evaluated in a randomized design, with four replications. The tests included purity, moisture content, one thousand seed weight, germination, cultural value, and dry matter weight. The data were subjected to ANOVA and Scott-Knott test, both with a 5% probability of error. It was concluded that certified cultivars/lots of black and white oat seeds marketed in Pato Branco are not significantly superior to saved seed lots/cultivars in terms of their physical and physiological quality.
