“…This method can lead to faster grape maturation measured by increased sugar concentration at harvest (Reynolds et al 2007), can have no significant effect (Percival et al 1994, or can decrease sugar concentration due to limitation of photosynthates (Iacono et al 1995, Koblet et al 1995. Similarly variable responses of berry pH and TA to leaf removal have been reported (Koblet et al 1995, Percival et al 1994, Reynolds et al 2007, highlighting the need for local, variety-specific investigations into the practice to determine suitability of this management practice to meet the fruit quality goals for sparkling wine production.…”

Abstract:The current understanding of the influences of climate and viticultural practices on fruit quality at harvest and on sparkling wine quality is reviewed. Factors such as variety, clone, planting density, pruning method, local climate and soils, and current and future climate warming are discussed in the context of achieving a desired harvest quality. A common observation was the relatively less intensive viticultural management applied to grapes destined for sparkling wines compared to table wines throughout the world. Few studies have focused on management of fruit specifically for sparkling wine production. Given that it is accepted that a lower pH, higher titratable acidity, and lower soluble sugars than table wine are considered desirable for sparkling wine production, the literature from viticultural studies for table wines which influence these desired fruit quality parameters has been reported. Specific findings on canopy management, leaf removal, and yield manipulation for the production of table wines indicate potential for application and development to optimize fruit for the production of sparkling wines. Fruit quality targets are remarkably uniform across international growing regions but distinct combinations of variety, clone, and management are currently used to arrive at those targets. Further, studies of viticultural management, particularly those that alter cluster temperature and exposure to incident light, yield manipulation, and fruit quality are likely to best inform production techniques that result in fruit quality ideal for the production of premium sparkling wines. New challenges include the need for increasing mechanization to maintain cost-effective production and climate warming, which affects the production of fruit for premium sparkling production in terms of flavor development and high acidity. Current trends include the diversification of growing regions to cooler regions that enable the production of high acid fruit and increased exploration of alternative varieties and clones that are better suited to a warmer climate.

“…Rootstocks also have a pronounced influence on the mineral nutrition of the scion, which should be considered when developing fertilization programs (Koblet et al 1996). Some rootstocks, such as Malègue 44-53 (44-53), have a higher affinity for potassium than magnesium and therefore may fail to take up sufficient magnesium from the soil.…”

“…A taxa fotossintética variou de 6 a 13 mmol m -2 s -1 durante o período da manhã, e às 12h, permaneceu ao redor de 10 mmol m -2 s -1 nas plantas irrigadas, valor normalmente observado na videira, na literatura (Koblet, et al, 1997;Regina & Carbonneau, 1997;Schultz, 1997). A partir do sétimo dia após a interrupção da rega, foram verificadas reduções significativas na fotossíntese (p<0,05) da cultivar Niágara Rosada no horário das 12h.…”

Este trabalho teve como objetivo avaliar o efeito da deficiência hídrica e de dois porta-enxertos nas trocas gasosas de mudas de videira cultivadas em vasos, nas condições de casa de vegetação. Utilizou-se como copa a 'Niágara Rosada' (Vitis labrusca), e como porta-enxertos, o 101-14 (V. riparia) e o 1103 Paulsen (V. rupestris x V. berlandieri). Doze dias após a suspensão da rega, o potencial hídrico foliar da combinação 'Niágara Rosada'/101-14 apresentou os menores valores (-2,80 MPa) em relação à 'Niágara Rosada'/1103 Paulsen (-2,10 MPa) nas plantas não-irrigadas, enquanto o teor relativo de água variou apenas entre os tratamentos hídricos. Com a evolução do estresse hídrico, houve uma sensível redução nas trocas gasosas da cultivar 'Niágara Rosada', que apresentaram valores próximos de zero, devido ao fechamento dos estômatos, sem diferenças entre os porta-enxertos. Somente após 12 dias sem rega, os porta-enxertos influenciaram a eficiência no uso da água e eficiência fotoquímica do fotossistema II, onde a 'Niágara Rosada' enxertada sobre o 101-14 apresentou valores inferiores ao 1103 Paulsen. Entretanto, durante o período de suspensão da rega, os porta-enxertos não influenciaram as trocas gasosas da cultivar 'Niágara Rosada', e apresentaram comportamento semelhante em condições de baixa disponibilidade hídrica.
