Abstract

Camu-camu has aroused the interest of various industries like natural preservatives, ice creams, juices, jellies, wines, natural dyes, but there is little technical information about the seeds. The objective of this work was to determine the biometric, physical and vigor characteristics of camu-camu seeds. Seeds originating from native populations of Roraima were used. The biometry was determined and the data were analyzed in Excel spreadsheet and calculated the mean, median, variance, standard deviation and seeds classified as small, medium and large, based on mass. The vigor was determined by electrical conductivity, seedling emergence, emergence velocity, plant height, stem diameter, in a completely causal design, with four replicates of 25 seeds. The average results for width, thickness, length, individual mass, volume, weight of one thousand seeds and number of seeds per kilogram showed large variability. The size of the seed has direct correlation with vigor, large seeds have greater vigor.
