“…In addition to the phenological stages, FLR was another important determinant of final TSS; this has already been demonstrated in previous studies (Carbonneau et al. 1977, Murisier and Zufferey 1997, Kliewer and Dokoozlian 2005, Petrie and Clingeleffer 2006, Dai et al.…”

Background and Aims: To analyse the genetic determinants of berry sugar content in grapevine varieties, a method that combined measurements of total soluble solids (TSS) from berries sampled at a fixed stage after veraison with data on the yield and the leaf area was tested. Methods and Results: Over three seasons, differences in TSS at harvest for Riesling and Gewurztraminer grapes were explained by differences in the veraison dates and in the fruit‐to‐leaf ratios. TSS, yield and leaf area were also evaluated for 120 genotypes, which were progeny from a cross between Riesling and Gewurztraminer. Thermal timescales (degree‐days) proved relevant for describing sugar accumulation in the parent varieties, and when berries were sampled at a fixed heat sum after veraison in the progeny, the genotypic variability of sugar content was considerably reduced compared with the measurements on the same date at the end of the season. A negative relationship between the fruit‐to‐leaf ratio and the sugar content was also detected in the progeny. Conclusions: The evolution of TSS during berry ripening can be described using thermal timescales. Additionally, information on the yield and the leaf area needs to be integrated to analyse the behaviour of genotypes. Significance of the Study: A method to characterize the genotypic effect on fruit sugar accumulation after eliminating the contribution of veraison dates and crop load was proposed.

“…A l'opposé, une alimentation hydrique non excessive réduit la croissance végétative et permet une accumulation importante d'assimilats dans les baies. L'effet favorable de la faible vigueur est liée à la modification du microclimat des parties aériennes (SMART et COOMBE, 1983) ainsi qu'à la meilleure répartition des assimilats entre l'appareil végétatif et l'appareil reproducteur (CARBONNEAU et al, 1977 ;FREEMAN et al, 1980). Il a été montré qu'en zone de climat tempéré, la régulation de l'alimentation en eau à un niveau faible est un facteur de qualité déterminant d'un terroir viticole (SEGUIN, 1970 ;DUTEAU et al, 1981;CARBONNEAU, 1986 ; VAN LEEUWEN et SEGUIN, 1994).…”

Influence of water status on vine vegetative growth, berry ripening and wine characteristics in Mediterranean Zone (example of Nemea, Greece, variety Saint-George, 1997)

<p style="text-align: justify;">The influence of grapevine water status on vine physiological mecanisms and vigour, as well as on berry ripening and wine characteristics, was studied during the summer of 1997 in the Nemea vine growing area (Peloponnesus, Greece). This involved three non irrigated vineyards planted with the local variety Saint-George (Agiorgitiko). These vineyards differed by their soil texture and by the presence of a water table within reach of the roots. The soil of the plot "A", located at 350 m in altitude, contained a high amount of gravel and stones between 0 and 50 cm in depth. The subsoil contained nearly 50 p. cent of clay. The plot "L" was located on a plain at 300 m in altitude. Its soil was very loamy. The plot "N" was located on a plain at 260 m in altitude. Its soil contained a high amount of clay and loam but its main caracteristic was the presence of a permanent water table within reach of the roots. Vine water status was evaluated throughout the season by measurements of leaf water potential Ψ. Additional measurements of soil water content were executed by means of a TDR moisture probe (Time Domaine Reflectometry). Water uptake of the vines showed great differences on the three plots. On the plot A, water uptake of the vines diminished brutally from June (pre-dawn Ψ= -0,2 MPa) through September (pre-dawn Ψ= -1,0 MPa); measurements of stomatal conductance in early September showed that stomata remained practically closed throughout the day. On the plot N, water was easily available to the vines throughout the summer. Pre-dawn leaf water potential remained between 0 and -0,2 MPa from June till September. Stomatal conductance, measured in early September, was high. On L, vine water status was intermediate: pre-dawn leaf water potential declined throughout the season, but not as dramatically as on A. Stomatal conductance, measured in early September, was intermediate between N and A. Water availability had a clear effect on vegetative growth. Growth slackening occured early in the season on A and late on N. On plot A, berries were smaller and showed high sugar and anthocyanin concentration and low malic acid content. Wine from A, obtained by mini-vinification (3,5 hl), was rich in alcohol, anthocyanins and tanins. On N, berries had a low sugar and anthocyanin content. Wine from grapes grown on N was poor in alcohol and polyphenolics. Berry and wine composition was intermediate on L.</p>

“…Reductions in vine size of K vinifera associated with overcropping have been well-documented in Europe (Basler, 1980;Carbonneau et al, 1977;Murisier et al, 1986) and in California (Weaver et al,1957;Weaver and McCune, 1960). Weaver and Pool (1968), however, found that overcropping 'Carignane', 'Ribier', and Thompson Seedless' vines produced no vine size differences over three seasons.…”

“…Cluster thinning of French-American hybrid grapes, such as 'De Chaunac' (Fisher et al, 1977;Looney, 1981) and 'Seyval blanc' (Reynolds et al, 1986), has led to improvements in fruit composition, yield consistency, vine size, and cane periderm formation. Vine productivity and fruit composition have also been improved by cluster thinning Vitis vinifera in California (Kasimatis, 1977;Kliewer and Weaver, 1971;Weaver and Pool, 1968), Israel (Bravdo et al, 1984(Bravdo et al, , 1985, Austria (Basler, 1980), France (Carbonneau et al, 1977), and Switzerland (Murisier, 1985;Murisier et al, 1986).…”

‘Riesling’ Grapes Respond to Cluster Thinning and Shoot Density Manipulation

Five-year-old ‘Riesling’ grape (Vitis vinifera) vines growing in the Okanagan Valley of British Columbia were subjected to three crop levels (full crop, two clusters per shoot, and one cluster per shoot) in combination with no shoot thinning or thinning to 24 shoots per meter of row. Reduction in crop level improved vine size and cane periderm formation slightly. Yield per vine was linearly related to crop level, but berry weight, berries per cluster, and cluster weight increased with decreasing crop level. °Brix and pH increased and titratable acidity decreased with reduction in crop level. Thinning to 24 shoots per meter of row provided some improvement in yield components and °Brix. Crop loads below 10 kg of fruit per kilogram of cane prunings are necessary to achieve adequate fruit maturity under Okanagan conditions.
