Phenology and production of blackberry cultivars in agroecological system

摘要

> face="Verdana, Arial, Helvetica, sans-serif" size="2">The aim of this research was to evaluate yield and quality of blackberry cultivars Tupy, Guarani, Caingangue, Cherokee and Brazos, and the 'selection 97' and 'selection 787' at Pelotas, in the Southern of Rio Grande do Sul State, under agroecological system. The plants were available in blocks varietal randomized in the orchard, with 10 plants per row, four lines with two cultivars per line. For statistic analysis of the fruit characteristics each year of evaluation (three) was considered as one repetition. The characteristics evaluate were the beginning and end of flowering and harvest, mass (g), number of fruit per plant, content of total soluble solids (°Brix), average production by plant (pl g-1) and estimated productivity per hectare (ha pl-1). In the Pelotas-RS region there is technical viability for blackberry growing at agroecological system. There was no difference between cultivars evaluated for yield, fruit number and total soluble solids content.
