"Italia" grape is one of the most important table grape cultivars grown worldwide. Gray mold, caused by Botrytis cinerea Pers. Fr., is one of the most important causes of postharvest decay of table grapes, and the control of this disease is very difficult because postharvest treatments with synthetic fungicides are not allowed in many countries. The objective of this study was to compare different types of pads releasing different doses of SO2 during cold storage to control gray mold in "Italia" table grapes grown under subtropical conditions. Grape bunches were harvested from a commercial field trained on an overhead trellis located at Cambira, state of Parana (PR), South Brazil. The grapes were packed into carton boxes (capacity, 4.5 kg) and subjected to... |

?BRS Isis? is a new hybrid seedless table grape tolerant to downy mildew with a goodadaptation to the tropical and subtropical climates. Gray mold, caused byBotrytis cinereaPers. ex Fr.is known as the most important postharvest mold in table grapes, causing extensive losses worldwide.As the postharvest behavior of ?BRS Isis? is still unknown, the objective of this work was to evaluatethe postharvest preservation andB. cinereamold control of this new grape cultivar, grown under thedouble-cropping a year system. Grape bunches were purchased from a field of ?BRS Isis? seedlesstable grapes trained on overhead trellises located at Marialva, state of Parana (South Brazil). Grapeswere subjected to the following treatments in a cold room at 1±1◦C: (i)... |

A aplicacao da calciocianamida (CaCN2) em videiras da cv. Italia, por ocasiao da poda, mas concentracoes 0,10, 20 e 30%, proporcionou uma resposta quadratica na percentagem de gemas, brotadas nas varas sem cobertura plastica, e na producao das plantas com varas com cobertura plastica; e uma resposta linear na percentagem de gemas brotadas nas varas com cobertura plastica, e na producao das plantas com varas sem cobertura plastica. Nas varas sem cobertura houve um aumento de 142% de gemas brotadas com a CaCN2 a 20%, e um aumento de 88% na producao para a dosagem de 30%. E nas varas com cobertura plastica houve um acrescimo de 203% de gemas brotadas para a CaCN2 a 30%, e um acrescimo de 79% na producao para as dosagens de 20 e 30%. A CaCN2 nao afetou a... |

O conhecimento da distribuicao do sistema radicular para o manejo de irrigacao e de grande valia para a quantificacao da lamina de agua a ser aplicada, principalmente em regioes semi-aridas, onde a agua, alem de ser fator de incremento de produtividade, e um importante fator de custo de producao. Por causa da expressiva area cultivada com videira (Vitis vinifera L.) irrigada, cultivar Italia, no Vale do Sao Francisco, a distribuicao do sistema radicular desta cultura foi analisada em um latossolo Vermelho Amarelo, textura media, com cinco anos de idade, espacamento de 4 x 2 m, sob irrigacao por microaspersao e por gotejamento, na Estacao Experimental de Bebedouro, pertencente ao Centro de Pesquisa Agropecuaria do Tropico Semi-Arido (EMBRAPA-CPATSA), em... |

Grapevine growing in areas with low rainfall as the Brazilian semi-arid requires irrigation to full fill plant water demand. The objective of this study was to evaluate the physiological and yield responses of grapevine to irrigation strategies in the Lower Middle Sao Francisco Valley, in Petrolina, State of Pernambuco, Brazil. The experiment was carried out over three consecutive growing seasons of drip irrigated ?Syrah? grapevine, grafted on 1103 Paulsen and planted in an Ultisol (Soil Taxonomy, USA). Full irrigation (FI), regulated deficit irrigation (RDI), and deficit irrigation (DI) treatments were designed in a randomized block with four replications. Mostly soil moisture depletion was observed until 0.6 m soil depth while higher moisture values and... |
