Fenologia, exigência térmica e produtividade de videiras 'Niagara Branca', 'Niagara Rosada 'e 'Concord' submetidas a duas safras por ciclo vegetativo

Abstract: RESUMO -Este trabalho objetivou avaliar a fenologia, a demanda térmica e a produtividade das cvs. Niagara Branca, Niagara Rosada e Concord submetidas a uma poda seca no inverno e a uma poda verde no final da primavera, visando à obtenção de duas safras de uva por ciclo vegetativo. O experimento foi conduzido em vinhedo pertencente à Estação Experimental Agronômica de Eldorado do Sul-RS, na safra de 2007/2008. As plantas foram submetidas a duas épocas de poda de inverno (22-07-07 e 20-08-07), em cordão esporona… Show more

“…The 'Concord' cultivar was the most stable in relation to the effect of the rootstocks; there was no significant difference in the thermal demand (Table 2), or on the cycle (Table 1) at the two evaluated harvests. The average thermal sum for the 'Concord' cultivar found in this study were consistent with the values observed in study realized in Prosser, WA, in which the thermal sums were 1503 and 1414 in the years of 2006 and2007, respectively (PRADUBSUK;DAVEPORT, 2011), and in Eldorado do Sul, RS, who reported 1554.4 to 1621.7 (ANZANELLO et al, 2012).…”

“…Meteorological data were obtained from the Instituto Tecnológico SIMEPAR in the Curitiba Station, and for DD calculation it was used a base temperature lower than 10 °C (MANDELLI et al, 2003;NEIS et al, 2010;PRADUBSUK;DAVENPORT, 2011;ANZANELLO et al, 2012) according to the equations proposed by Villa Nova et al (1972):…”

“…Apesar de haver um alongamento do ciclo quando a poda é realizada em maio e junho, o fruticultor consegue antecipar a colheita em torno de 56 dias e 28 dias, respectivamente, em relação à poda tradicional, realizada no final de julho (Tabela 2). Resultados positivos de antecipação de safra a partir da antecipação da poda de inverno também foram encontrados por Anzanello et al (2012), para a videira.…”

“…It should be noted, however, that, before planting vineyards or introducing grape varieties into new regions, the phenological responses to the soil and climatic conditions of the site have to be assessed for an improved technological management (Anzanello et al, 2012).…”
