“…Nonetheless, its efficiency is cultivar‐dependent: Zabadal and Bukovac () found that berry size and bunch compactness could be increased in the CPPU‐sensitive cvs Himrod and Vanessa, whereas no significant effect was recorded in the CPPU‐insensitive cvs Lakemont Seedless, Concord and Niagara. Lastly, ethephon has been used to stimulate spontaneous abscission of mature grape berries (Rizzuti et al , Ferrara et al ) and, together with abscisic acid, to improve the colour of red grapes (Leão et al ). El‐Banna and Weaver () evaluated the effect of ethephon in the compactness of Thompson Seedless bunches, but they found no significant modification after its use.…”

Bunch compactness (or density) is a grapevine specific trait that affects the commercial quality and sanitary status of wine and tablegrapes. Compact bunches are more susceptible to diverse pests and diseases such as Botrytis bunch rot and their berries ripen more heterogeneously, causing important economic losses through a reduction in crop yield and grape and wine quality. Bunch compactness is determined by the fraction of the morphological volume of the bunch that is filled by berries, but this simple definition contrasts sharply with the difficulty to measure it. While there are several objective and quantitative methods available to measure bunch compactness, the lack of a consistent approach between researchers makes comparing measurements difficult. The complexity of bunch compactness initially arises from the several bunch and berry traits that influence it, and from the distinct effects that these traits may cause in different cultivars. In addition to this genetic effect, diverse environmental signals impact on bunch compactness by affecting those primary factors that contribute to the solid component of the bunch (berry number, berry size) or to its spatial arrangement (rachis architecture). Last, several viticultural approaches, including agronomic techniques and growth regulators, have also proven to affect bunch compactness in different ways. This review aims to discuss present knowledge about this relevant grapevine trait.

Most of the postharvest losses on table grapes are related to the berry abscission and stem browning that affect the product appearance, reducing its commercial value and becoming a problem to table grapes production chain worldwide. The aim of this study was to evaluate the effect of pre-harvest application of foliar fertilizers, plant growth regulators or a mix of both on table grapes var. ‘Sweet Globe’ quality parameters. All treatments were applied in a volume of 100 L ha-1 after 75 days (pre-softening), 95 days (ten days before harvest) and 103 days (two days before harvest). The clusters were harvested at the commercial harvest maturity stage, packed and stored in a cold room (0 °C and 95% RH), being evaluated for berry abscission, stem browning, firmness, abscission force, soluble solids, acidity, stem dry matter, stem water activity and weight loss at harvest and at 14, 42 and 56 days of storage. Although there was no statistical difference from control, the pre-harvest application of Hold® + Gibberellin resulted in clusters with lower percentage of berry abscission and the application of Kamab® resulted in clusters with lower stem browning, both evaluated after 56 days of storage.

“…Concord, Morris y Cawthon (1981, 1982a, 1982b, estudiaron los efectos del etefón sobre la abscisión del fruto en función de la dosis y el momento de aplicación, y observaron que concentraciones entre 400 y 800 mg•L -1 aplicadas entre 8 y 20 días antes de la vendimia, reducían significativamente la FDF y promovían la cicatrización de la zona de abscisión. En tres cultivares distintos de Vitis rotundifolia, encontró incrementos significativos del número de bayas cicatrizadas tras aplicar entre 600 y 1200 mg La caída prematura de frutos puede ser un efecto muy negativo de los tratamientos de etefón como agente de abscisión (Mainland y Nesbitt, 1974;Mainland et al, 1977;Hedberg y Goodwin 1980;Fidelibus et al, 2007a;Rizzuti et al, 2015), ya que puede dar lugar a una pérdida significativa de cosecha. Por otra parte, diversos autores han puesto de manifiesto que los tratamientos de etefón en los días previos a la vendimia pueden tener un efecto de deshojado de las plantas (Eynard, 1970;Hedberg y Goodwin, 1980;El-Zeftawi, 1982), lo cual perjudica el agostamiento y podría tener un efecto depresivo en las cepas.…”

“…Thompson seedless han promovido la cicatrización de la zona de abscisión, alcanzando un valor medio al final del Ensayo 2, del 34% de las bayas. El etefón en "Verdejo" no incrementó significativamente la presencia de tejido cicatricial en contra de lo observado por Morris y Cawthon (1981) y Rizzuti et al (2015), con dosis de producto a partir de 400 mg•L -1 , en cv.
