“…Matsui et al (1985) observed that a signifi cantly larger amount of 14 C was trans locat ed into berries at Stages I and III compared with Stage II. Girdling in grapevines has been reported to increase berry weight and advance fruit maturity by altering assimilate translocation and distribution (Harrel and Williams, 1987;Zabadal, 1992). In our experiment, a single girdling in the later portion of Stage I presumably interrupted the assimilate translocation out of the girdled shoot, resulting in enhanced assimilate supply to the berry, although this was not actually measured.…”

“…For better un der stand ing of these mechanisms, we investigated the growth kinetics and related physiological and biochemical processes occurring dur ing the berry growth, and the relationship among assimilate competition, double-sigmoid growth kinetics and endogenous hormone levels in grape berries. Considering that cane-or trunk-girdling has been reported to affect berry weight and advance fruit maturity by changing the assimilate translocation and dis tri bu tion in grapevines (Harrel and Williams, 1987;Peruzzo, 1994;Zabadal, 1992), we designed two shoot girdling treatments to change indirectly the assimilate supply to berries of two cultivars, one seeded ('Kyohoʼ) and one seedless ('Seedless Wuhehongʼ), to help understand the role of assimilate supply in berry de velop ment. 'Seedless Wuhehongʼ is stenospermocarpic, with normal pollination and fertilization followed by embryo abortion.…”

The relationship of assimilate supply to grape (Vitis vinifera L.) berry growth and development was studied with a seeded (`Kyoho') and a seedless (`Seedless Wuhehong') cultivar. A single shoot girdling between the second and third nodes below the basal cluster at the end of Stage I of berry growth shortened Stage II (the lag phase) of `Kyoho' grape berries by 10 days, and eliminated Stage II in `Seedless Wuhehong' grape berries. Double shoot girdling between the second and third nodes below the basal cluster and above the upper cluster, respectively, at the same time at the end of Stage I, advanced Stage II by 3 days in both cultivars. Normal accumulation of dry weight in the `Kyoho' grape berry is in a double sigmoidal pattern, but it became a single sigmoidal pattern in response to a single basal girdling. The highest percent moisture in berries was at 20 days after full bloom. Rapid changes in berry pectin substances lagged behind those of soluble solids and titratable acidity, and behind the onset of berry softening at veraison in `Kyoho', but not in `Seedless Wuhehong', for which the three processes were concurrent. It is suggested that the slow growth of the berries during Stage II is a result of a decrease in the rate of water accumulation on a whole berry basis and a decrease in accumulation of dry matter in the skin and flesh (pericarp) due to assimilate competition within grapevines and within berries. The relationships between levels of endogenous hormones (IAA, GA3, zeatin, zeatin riboside, and ABA) and berry growth were also studied with `Kyoho' grapes. The results showed that the slow growth of grape berries during Stage II was associated with assimilate competition between the skin-flesh (pericarp) and seeds, and with peak shifts of concentrations of IAA, GA3, zeatin and zeatin riboside. Changes in ABA levels were closely associated with ripening and senescence during late Stage III.

“…Berry abscission normally begins at flowering and can occur for up to 4 weeks after anthesis depending on the weather conditions (Kassemeyer and Staudt 1983); it is during this period that fruitset is determined. Other authors also found an increase in grapevine yield components due to shoot girdling (Reynolds andde Savigny 2004, Williams andAyars 2005), which was explained by changes in translocation and distribution of photoassimilates (Harrell and Williams 1987, Roper and Williams 1989, Zabadal 1992, Williams et al 2000. Therefore, fruit yield may provide an averaged and integrated record of carbohydrate availability over a large period as proposed by Caspari et al (1998).…”

“…Girdling may affect various physicochemical parameters related to fruit composition, such as accumulation of sugars, organic acids and phenolic substances, depending on the phenological timing of the treatment (Basile et al ). Zabadal () found that cane girdling of Himrod grapevines when the berries were ‘pepper size’ increased the bunch mass and the number of berries per bunch by over 100%, the berry mass by 17% and the yield by 66%, but it consistently reduced the TSS in the fruit. Ferrara et al () cane girdled the tablegrape cv.…”

Background and Aims Some grapevine cultivars such as Malbec have unstable yield, due to poor fruitset or fruitlet abscission. The phenomenon is known as ‘shatter’ and this study aims to explore the potential of applying the shoot girdling technique at flowering, to direct the carbohydrate partitioning towards inflorescences and reduce shatter. Methods and Results Fruitful Malbec shoots were girdled above the apical bunch, below the basal bunch, double girdled or not girdled (Control) during 2017 and 2018. Most vegetative growth parameters were unaffected, but shoots widened and the leaf expansion improved in the fruit zone. Fruitset doubled compared to that of the Control, ovary abortion was reduced, and fruit yield increased, mainly due to a greater number of small berries in the base and double girdled treatments. In addition, base girdling increased TSS per berry, reducing the concentration of phenolic substances in the normal size berries. Girdling effects were consistent during both seasons. Conclusions Shoot girdling below the basal bunch proved to be effective in reducing shatter. The increase in carbohydrate supply available to the inflorescences during flowering was able to augment their weak sink strength relative to the perennial organs. Significance of the Study The study contributes to an understanding of the importance of the photoassimilates flow towards inflorescences in reducing shatter and increasing yield in Malbec vines.

“…Em videiras, o anelamento foi realizado pela primeira vez em 1745 e verificou-se com a adoção desta técnica o aumento da massa dos bagos e o adiantamento da maturação (Husmann, 1898 citado por Zabadal, 1992). Segundo Peruzzo (1994) o anelamento de ramos é uma prática cultural muito usada para uva de mesa em outros países, pois além de antecipar a maturação, também pode promover a uniformização do tamanho dos frutos, melhorando a aparência final dos cachos, porém pouco se sabe a respeito das respostas ao anelamento das videiras cultivadas no Brasil.…”

The present work was developed to evaluate the effect on the cluster, berries and raquis characteristics of Niagara Rosada and Venus table grapes of increasing doses of gibberellic acid associated or not with branch girdling and/or cluster blunt. Two experiments, for each cultivar, were accomplished in the northwest area of São Paulo State, Brazil, in a randomized block design, with five replications, being fourteen and eighteen treatments for 'Niagara Rosada' and twenty-eight treatments for 'Venus'. The gibberellic acid in the doses of 0; 10; 22,5; 35; 47,5; 60 and 72,5ppm, was applied, through the total immersion of the clusters, fifteen days after the full flowering, except for the second experiment with 'Niagara Rosada', in which was added up two more doses of 85 and 97,5ppm. The girdling in the productive branches was also accomplished in this same time. In the first experiment with 'Niagara Rosada' no effect of girdling was detected on the berry mass and size. Also, gibberellic acid (35ppm) alone increased cluster and berry mass and size. This same dose when associated with girdling provided increase in the soluble solids. In the second experiment with 'Niagara Rosada', larger increments on berry size and mass, as well as, pedicels diameter were obtained with gibberellic acid (60ppm) associated with branch girdling. The largest increments on cluster mass and width and on the berry number per cluster, were xi obtained applying gibberellic acid (35ppm) associated with girdling. In the first experiment with 'Venus' seedless table grape in 1999 it was detected that the higher the concentrations of gibberellic acid, the larger were berry length, width and the mass. Also, girdling associated or not with cluster blunt increased these same characteristics. In the second experiment with 'Venus' cultivar it was noticed that the higher the concentrations of gibberellic acid, the larger were cluster and raquis length and width. Gibberellic acid (35ppm) associated with girdling only or with cluster blunt provided the largest increase on cluster and raquis masses and the largest berry number per cluster. Larger berries were obtained with gibberellic acid (60ppm) associated with girdling only or with cluster blunt. The largest berry mass was obtained with gibberellic acid (47,5ppm). Also, it was detected a decrease in soluble solids with higher concentrations of the vegetable regulator associated with girdling.
