The objective of this study was to evaluate the influence of the storage environment on quality ofamaranth seed. The seeds were placed in polyethylene bags and stored for ten months in cold andin laboratory conditions. To evaluate the physiological quality of seeds, we determined the water,the one hundred seed weight, germination and vigor. The storage of amaranth in the cold chamberwas more efficient for the conservation of physiological seed quality.O objetivo deste trabalho foi avaliar a Influência do ambiente de armazenamento na qualidadefisiológica de sementes de amaranto. As sementes foram acondicionadas em embalagem depolietileno e armazenadas durante dez meses em câmara fria e em condições ambientais delaboratório. Para avaliação da qualidade fisiológica das sementes, foi determinado o teor deágua, o peso de cem sementes, a germinação e o vigor. O armazenamento de amaranto emcâmara fria foi mais eficiente para conservação da qualidade fisiológica das sementes. Influence of environment on the storage quality of seed physiological amaranthAbstractThe objective of this study was to evaluate the influence of the storage environment on quality ofamaranth seed.
