| Resumo: O objetivo deste trabalho foi avaliar a influência dos porta-enxertos 'IAC 766 Campinas' e '106-8 Mgt Ripária do Traviú' sobre as características físico-químicas do mosto e do vinho das uvas 'IAC 116-31 Rainha', 'IAC 21-14 Madalena' e 'BRS Lorena'. O mosto das uvas foi avaliado quanto ao pH, sólidos solúveis (SS), acidez total (AT) e relação SS/AT. No vinho, realizaram-se as seguintes análises físico-químicas: densidade, teor alcoólico; acidez total, volátil e fixa; pH; extrato seco; açúcares redutores; extrato seco reduzido; álcool em peso/extrato seco reduzido; dióxido de enxofre livre e total; índice de polifenóis totais (I 280), polifenóis totais, flavonoides; e atividade antioxidante. As características do mosto da 'IAC 21-14 Madalena' não... |

| Abstract: The objective of this work was to evaluate the phenological characteristics and yield of 'Vênus' grapevine (Vitis labrusca) grafted onto different rootstocks, as well the physicochemical traits of its grapes during the 2013, 2014, and 2015 crop seasons. The evaluated rootstocks were 'IAC 766', 'IAC 572', 'IAC 313' and 'IAC 571-6'. The length of the main phenological stages of the grapevine and its thermal demands were assessed during two growing seasons and expressed as days after pruning and degree-day sum, respectively. Grapevine yield and berry physicochemical characteristics were assessed during three crop seasons. 'Vênus' phenological cycle and thermal demands, as well as the chemical characteristics of its grapes, varied with the climate... |

| ABSTRACT Pruning guava trees at different times is an important management tool that allows year-long staggering of fruit production. In this context, this study aimed to evaluate the phenological characteristics, yield and fruit quality of the 'Paluma' guava tree at different pruning times in Botucatu, SP. The study used a completely randomized design with four treatments, four replicates and a useful experimental plot plant. The treatments consisted of four different pruning times, August 27, September 11, September 26 and October 11. The following phenological phases were evaluated: branch establishment, flowering, early fruiting, fruit ripening and harvesting. It was determined the number of flower buds, fixed fruits and fixation index fruit were... |
