The production of nursery is one of the most important steps in fruit crop systems. The rooting of semihardwood cuttings is largely influenced by the substrate composition, container, matrix genotype and physiological stage. The aim of this work was to evaluate the effect of different substratum composition on growth of berry plant genotypes propagated by stem cutting in dibble tubes condition under na intermittent nebulization system in green house, during 60 days. A block factorial design (4x2) comprising four organic sources e two berry genotypes was established. The organic sources of humus (vermicompost), carbonized rice hulls, ripe coir dust and leave dust from carnaúba (Copernicia cerifera) were mixed with na arenic Hapludult (1:1 proportions, v/v) to rooting and growth of P-91 and P-26 berry genotypes in tubules condition. Rooting percentage, dry mass of roots (g), number of leaves (NF) and dry mass of aerial part (g) were measured. The soil and humus mixture was suitable for rooting of semihardwood cuttings and was reflected on the number of leaves and aerial dry mass accumulation. The berry genotype P-26 presented potential for cutting process.
