“…drastic reductions) when a similar form of severe shoot trimming was performed after fruit set (berry diameter 3-4 mm) by excising the internode just above the distal clusters of Grenache and Tempranillo (Martínez de Toda et al 2013). Then again, analogous treatments of our study (trimming to the 10 th node) performed early in the season (pre-veraison) not only elongated clusters but also increased yield and Brix (Cartechini et al 2000) except for its combination with nitrogen application, wherein shoot trimming decreased fruit quality (Keller et al 1999). While the Brix, pH, and yield were reduced, the anthocyanin profile and total anthocyanins remained unaffected by shoot trimmings.…”

“…The obvious one is the reserves, which are stimulated to hydrolyze by pruning activities into sugars so as to remobilize them into the sink organs-in-need (Clair-Maczulajtys et al 1996). Conversely, shoot-trimming during pre-veraison (Cartechini et al 2000) or when shoots were trimmed to two leaves per cluster reduced polyphenols including anthocyanins due to inhibition of anthocyanin biosynthetic enzymes (Wu et al 2013). The same phenomenon is responsible for anthocyanin losses under conditions of high temperature (Mori et al 2007), which explains the lower anthocyanin levels in 2011, a relatively much warmer season than the preceding wet seasons receiving high rainfall (190-455 mm) from budbreak to harvest.…”

Postveraison Shoot Trimming Reduces Cluster Compactness without Compromising Fruit Quality Attributes in Organically Grown Sangiovese Grapevines

Vine performance following preveraison shoot trimming is well documented, but the consequences of this treatment later in the season are poorly understood. Here, a four-year study was conducted in a mature vineyard of Sangiovese (clone 12T) grafted onto Kober 5BB rootstock at a spacing of 1 m x 2.8 m (intra-and interrow) to analyze the influence of postveraison shoot trimming on vine growth characteristics, cluster architecture (cluster compactness), and yield from a physiological viewpoint. The treatments consisted of shoot trimming during postveraison in a randomized block design with eight replications (six vines each). Three treatments were imposed when soluble solids reached 15 Brix in August (40 to 45 days before expected harvest): light trimming (14 nodes), severe trimming (10 nodes), and an untrimmed control. Following the treatments, vine growth characteristics, cluster morphology, and fruit quality attributes were measured. Postveraison shoot trimming (especially severe trimming) reduced cluster weight, cluster compactness, productivity, and total yield. Effects on fruit quality included lowering of Brix and pH, with minor effects on titratable acidity, yeast assimilable nitrogen, the anthocyanin profile, and total anthocyanins. These results demonstrated that postveraison shoot trimming can be a valuable production practice by reducing cluster compactness without compromising overall fruit quality in Sangiovese

“…Realizada no início da floração e na fase de grão de ervilha, a desponta causou diminuição da produtividade do vinhedo quando se deixou somente uma gema acima do último cacho de uva (VASCONCELOS; CASTAGNOLI, 2000;DARDENIZ et al, 2008), o que foi devido a um aumento do crescimento vegetativo da videira. Entretanto, outros trabalhos evidenciam que houve aumento da produtividade do vinhedo em face da desponta (CARTECHINI et al, 2000).…”

CANOPY MANAGEMENT AND ITS EFFECT ON THE YIELD COMPONENTS OF THE MERLOT GRAPEVINEABSTRACT -Summer pruning is a cultural practice used to manage vineyard canopies, which has the main objective to improve grape and wine quality. In this way, this experiment was carried out between the 1993/1994 and 1996/1997 vintages using different summer pruning modalities. It was performed in a Merlot vineyard trained in the pergola system. There were 12 treatments and three replicates, where the experimental design was in complete blocks. The treatments consisted of control and 11 different summer-pruning modalities, all related to sprouting, topping, and leaf removal, some of them performed in different periods of the grapevine-vegetative cycle. The principal component 1 of the principal component analysis (PCA) of each year shows that the treatment 10 (sprouting + topping + leaf removal performed in the beginning of the bloom time, taking off all leaves below clusters) was discriminated in all years and treatments 7 (leaf removal performed 21 days before harvest, taking off half of leaves below clusters) and 6 (leaf removal performed 21 days before harvest, taking off leaves below clusters) in three of them; the PCA of the average of four years also shows this discrimination among them. It is shown that treatment 10 had a more intense summer pruning, characterized by variables indicating grapevines with lower vigor and yield than the other treatments.

“…a single high wire trellis) where a pre-flowering shoot trimming might become necessary to induce mostly upright shoot growth (Poni et al, 2014). In different red and white grapevine cultivars grown on fertile soil and trained to a single high wire trellis, the hedging at the 9-10th node on primary shoots, carried out one week after bloom, increased the contents of TSS, phenols and anthocyanins in the red cultivars and reduced the TA and juice pH in all the cultivars (Cartechini et al, 2000). Latehedging, five weeks after bloom, instead reduced yield and TSS content as well as anthocyanins content in red cultivars.…”
