dc.description.abstractother1Abstract: The cultivation of blackberry (Rubus sp) has aroused the interest of many producers in the world, as the plants come into production in a year after planting, and the demand for fresh and processed industries also increased However, the cultivation of this fruit tree under subtropical conditions with mild winter is still unknown The objective of the work was to evaluate the performance of blackberry cvs Tupy and Xavante grown in subtropical area The experiment was conducted at Experimental Station of Londrina State University, PR, Brazil, during two consecutive seasons, 213 and 214 The experimental design was a randomized complete block, with five replications, and each plot was composed of five plants of each cultivar It was evaluated, through visual observations, the duration in days of each phenological stage of both cultivars, as follows: start of bud sprouting; start of flowering; start of fruit maturation; start of fruit harvest; end of flowering; and end of harvest It was also evaluated the duration in days of the following fruit development stages: dormant buds; bud burst; flower bud; half open flower; full open flower; unripe green berry; early ripening pink berry; ripening pink berry; and ripe berry The physicochemical characteristics of production such as length, diameter, weight, total soluble solids (TSS), titratable acidity (TA), TSS/TA ratio, pH, color, total anthocyanins and polyphenols concentration of berries, and yield were also evaluated The phenological development of ‘Tupy’ and ‘Xavante’ blackberries were directly influenced by winter conditions, influencing bud sprouting, flowering and fruit harvesting period In 213 season, ‘Tupy’ had comparatively late start of growth cycle than ‘Xavante’ but both ended fruit harvest at same time in early summer In 214 season, ‘Xavante’ maintained the characteristic of earliness, and ‘Tupy’ also resumed growth cycle comparatively earlier to last season The fruit development duration was quite similar for both cultivars Due the subtropical conditions, it is proposed the possibility to grow blackberries under two crops a year to optimize the system of production Regarding physicochemical characteristics of cultivars, ‘Xavante’ presented lower means than ‘Tupy’, especially yield, but presented good chemical characteristics (TSS and pH) and early percent yield accumulation ‘Tupy’ produced fruits of large size with optimum TSS and pH, had an attractive color, and obtained high yield and higher percent yield accumulation towards end of harvest season The production of these cultivars in subtropical conditions can be a good choice for growers to commercially produce fruits for fresh consumption and processed industry due to good yield and optimum quality attributespt_BR
