Avaliação da qualidade fisiológica das sementes de arroz (Oriza sativa L.) armazenadas em diferentes tipos de embalagens e microrregiões do Estado da Paraíba.

Abstract

This work had the objective of influencing several storage sites in the State of Paraíba, representative of the microregions: homogeneous of Litoral Paraibano (João Pessoa), Agreste of Borborema (Campina Grande) and depression of Alto Piranhas (Patos), under warehouse conditions (Oriza sativa L.) for a period of six months in two types of packaging (metal containers and burlap sacks). The experiment was set up according to a 3x2x7 factorial scheme, using a completely randomized design with four replicates for germination and vigor to three replications for moisture content. Seed evaluations were done monthly. According to the results obtained, it was concluded that the best location to store rice seeds, among the three environmental conditions studied, was Campina Grande using either of the two packages, followed by Patos with the seeds packed in sacking bag and later João Pessoa with the seeds packed in metal container.
