Germinação de sementes de quinoa com diferentes períodos de armazenamento

Abstract

This work aimed to evaluate the effect of different storage periods and the number of days to the germination of quinoa seeds. The seeds were obtained from plants cultivated under field conditions in the agricultural year of 2012/2013, in the municipality of Marechal Cândido Rondon, PR. The survey was conducted in the Seeds Technology Laboratory, at the State University of West Parana - UNIOESTE. The treatments consisted of the association between six storage periods (36, 85, 119, 146, 177 and 270 days) and eight days of germinated seeds counting, kept at 25 °C without photoperiod in four replicates of 100 seeds each. Germinating boxes (Gerbox) were used, containing germination paper on which the seeds were disposed. The quinoa seeds germination decreases with storage time increase, which also slows the germination. The count of the number of germinated seeds has to be performed on the eighth day after the assembly of the Standard Germination Test in quinoa.
