Phenologyc behavior grapevine, of CV. Patrícia in different times of fructification pruning in Goiás

The experiment was developed in the council of Silvânia, State of Goiás, in commercial orchard of grape `Patrícia' (IAC 871 - 41) during the period of February to October of 2003. The objectives of this work were to evaluate the phenologycal behavior and the characteristics of the bunches and berries of Patrícia cultivar in different pruning times (March 13, March 28, April 12 and April 27). Durations of the stage (pruning - harvest) were of 152, 172, 185 and 178 days for the prunings accomplished on March 13, March 28, April 12, and April 27, respectively. The pruning times did not affect the size and the form of the bunches significantly, however, these became large with length of about 20.52 cm. The largest berry diameter was found in the pruning accomplished on April 27 with 19.14 mm, patterns considered appropriate for cultivation. The different pruning dates did not show influence on total soluble solids, with an average of 18.4 ºBrix, however there was no variation for the total acidity titratable, evidenced in the prunings of March 13, and April 27, respectively, with 1.44 and 0.87g of tartaric acid /100 mL of grape juice. The different pruning dates affected significantly the SST/ATT relationship, being the smallest relationship found in the pruning date of March 13 with 13.0 and the largest in the pruning date on April 27 with 21.9.
