Germina？？o e vigor de sementes de milho recobertas e viabilidade do inóculo durante o armazenamento

the aim of this study was to evaluate the physiological quality of stored seeds covered with different mixtures and the period of survival of the bacterial cells in the seed coatings. h. seropedicae z67 br 11175 was used in this study. the 'uenf 506-8' corn seeds were coated with a mixture preparation consisting of lime, jnfb semi-solid medium, water and cement. the seeds were conditioned for three months in paper bags and stored under two conditions: laboratory (at a temperature of 26.2 oc and 61.5% relative humidity) and bod chamber. every 30 days of storage determinations of the water content, counting of bacteria, and evaluations of the physiologic quality of the seeds were performed. the coating of the seeds did not modify the natural loss of physiological quality of the seeds during the storage. among the storage conditions studied, the most appropriate for the maintenance of the seeds was the 26.2 oc and 61.5% of relative humidity. bacterial cells were detected in the roots of plants originated from coated seeds inoculated with bacterial and stored up to 60 days independently the of storage conditions.
