“…Unexpectedly, summation of active T required for each treatment to reach the threshold of 20°Brix from budburst varied with the year, the shift in date being most notable in 2015. It is likely that the prolonged high T days in 2015 impaired vine physiology and carbon balance, as repeatedly reported (Palliotti et al , , Flexas et al , Poni et al , Greer and Sicard ). That Pinot Noir is an early‐season cultivar requiring a temperature during ripening compatible with cool viticulture areas tends to support this view (Jackson and Cherry , Jones and Davis ).…”

Background and Aims: The postponement of spur pruning after budburst has recently been proposed as a simple and inexpensive way to delay sugaring, maintain acidity and contain yield in spur-pruned trellised grapes. Yet, no long-term data are available for the widely adopted cane pruning system. Methods and Results: Mature field grown Vitis vinifera L. cv. Pinot Noir vines were subjected for three consecutive years to the following treatments: standard winter pruning (WP), double pruning (DP), where shortening and positioning of the selected cane is postponed, and late pruning (LP), where all pruning operations are postponed. Postponed pruning was performed when shoot growth from node 10 of the unpruned canes had reached an average stage of more than three unfolded leaves. Phenological and ripening dynamics, yield components and must composition were determined. Double pruning did not affect phenology and overall vine performance compared to that of WP. Conversely, LP significantly delayed ripening over 2 trial years; LP also slightly increased whole-vine and single-cane phenological variability, whereas yield per vine was reduced by 35% as compared to that of WP because of lower shoot fruitfulness. Conclusions: If repeated over several seasons, late WP applied to a cane-pruned system when the distal part of the cane has already burst an average of three leaves can become effective at delaying phenology and extending maturity into a cooler season. Significance of the Study: We have validated a simple technique suitable for preserving balanced must composition required for a range of sparkling wine styles.

“…Williams (1996), who included roots and trunk, calculated that in three different phenological stages (147,206,and 253 DOY), ≈50% of the total CO 2 required by 'Chenin blanc' grapevines grown in California was used for respiratory purposes. On mature vineyards of 'Sangiovese' grown in central Italy, excluding the roots, a range of 36% to 49% of DM produced by the vine during the season was lost by respiration processes (Palliotti et al, 2003).…”

This paper describes and evaluates the reliability of a model for prediction of daily carbon balance and dry matter (DM) accumulation in vertically shoot positioned grapevine (Vitis vinifera L.) canopies based on the user-friendly STELLA simulation software. Validation of the model was produced for potted 'Cabernet Sauvignon' grapevines at both low canopy density [LD (≈10 shoots/m of row)] and high canopy density [HD (≈20 shoots/m of row)] by comparing, ona seasonal basis, the modelled daily CO 2 balance with the diurnal net carbon exchange rate (NCER) measured using a whole-canopy enclosure method. Estimated daily total photosynthesis (P n ) was linearly correlated with measured NCER for LD (r 2 = 0.87) and HD (r 2 = 0.86), thereby indicating that despite its simplicity the model led to a fairly good degree of precision, although it tended to slightly underestimate (5% to 8% less) the measured rates and scattering increased at high values of CO 2 fi xations. Daily total respiration (R) for LD treatment was 29.0% of total daily P n , with clusters, leaves and stems accounting for 11.8%, 46.7%, and 41.5%, respectively. Daily total R was 24.2% of total daily P n in HD treatment and single organs contributed 22.3% (clusters), 41.6% (leaves), and 36.1% (stems). The model estimated that 1604 and 1893 g DM per vine accumulated at harvest for LD and HD treatment, respectively, whereas destructive sampling of leaves, stems and clusters yielded 1475 ± 64 g per vine for LD treatment and 1730 ± 96 g per vine for HD treatment, respectively, corresponding to the 91% and 92% of the DM estimated with STELLA, which in its present version does not take into account root respiration.
