Qualidade fisiológica de sementes de mamona armazenadas em duas microrregiões da Paraíba em diferentes embalagens.

Abstract

The small farmers have a lot of difficulties in conserving their seeds, being that the physiological and physical quality assumes an important role, for an appropriate seeding, which implies on the stability of the plantation, as well as the productivity and the quality of the production. The objective of this work was to evaluate the physiological quality of mamona seeds in different environments, in the cities of Campina Grande and Patos-Pb, four different types of containers, such as freezers, multi-layer papers, nylon bags and 2 Lt. plastic bottles (pet), and four different storage periods (0, 2, 4 and 6 months), over the viability of germination and vigor, in relation to humidity in the mamona seeds, variety BRS Nordestina The statistical alignment was totally casual, disposed in a factorial of 3 x 3 x 4 with four repetitions. At the end of the experiment the physiological quality was not affected during the storage period, being that the 2 Lt. plastic bottle was the most indicated for storageand the best enviromewnt with the best conditions was the city of Patos-Pb., during the period that was studied.
