Abstract: The objective of this work was to compare the effect of different times of leaf removal on the vegetative-productive efficiency and on the chemical and physical characteristics of 'Cabernet Sauvignon' clusters in a high-altitude region of the state of Santa Catarina, Brazil. The experiment was conducted in the 2015 and 2016 vintages, in a commercial vineyard, located in the municipality of São Joaquim, in the state of Santa Catarina, at 1,230-m altitude. The treatments consisted of different times leaf removal in the cluster zone, in the following phenological stages: full bloom, buckshot berries, pea-sized berries, veraison, and 15 days after veraison, besides a control without leaf removal. The evaluated variables were subjected to the analysis of variance and compared with the Scott-Knott test, at 5% probability. In a high-altitude region, leaf removal provides more adequate indices for plant vegetative:yield balance. It also increases yield when performed during the pea-sized berry and veraison stages, increases the fertility index when performed during the pea-sized berry stage, and improves the chemical composition of 'Cabernet Sauvignon' grape when performed up to the pea-sized berry stage. The obtained results show the importance of early leaf removal to obtain must with potential for the production of quality wines.

Abstract: The objective of this work was to evaluate the phenolic composition of wine from 'Cabernet Sauvignon' (Vitis vinifera) grapes subjected to leaf removal management at different timing, in a high-altitude region. The experiment was carried out in the 2015 and 2016 vintages, in a vineyard located in the municipality of São Joaquim, in the state of Santa Catarina, Brazil. The treatments consisted of different periods of leaf removal in the clusters, at five phenological stages ‒ full bloom, buckshot berries, pea-sized berries, veraison, and 15 days after veraison ‒, and of a control without leaf removal. At harvest, 50 kg of each treatment were collected for winemaking. The contents of gallic acid, catechin, p-coumaric acid, vanillic acid, resveratrol, quercetin, rutin, and kaempferol were evaluated. The results showed the importance of leaf removal before veraison, to obtain wine with a higher concentration of phenolic compounds, which favors wine quality. The leaf removal management promotes the increase of gallic acid, vanillic acid, p-coumaric acid, resveratrol, quercetin, and kaempferol in wine. The early leaf removal before veraison results in increases in vanillic acid, p-coumaric acid, resveratrol, quercetin, and kaempferol. The wine made from grapes not subjected to leaf removal shows higher values of catechin and rutin.

Lack Of Knowledge

There is a lack of knowledge regarding Lepidoptera species in altitudinal grassland areas, especially in the state of Santa Catarina, in southern Brazil. Here we report some records of Vanessa braziliensis (Moore, 1883) and Urbanus zagorus (Plötz, 1880) in high altitude areas. We have likely registered both the first record of U. zagorus for the state of Santa Catarina and the highest altitudinal record of V. braziliensis in Brazil.

Abstract: The objective of this work was to evaluate the effect of different pruning methods on the yield performance and on the oenological potential of Vitis vinifera 'Nebbiolo', cultivated in high-altitude regions of Santa Catarina state, Brazil. The work was carried out in a commercial vineyard located in São Joaquim, SC, during the 2011/2012 and 2014/2015 crop seasons. The treatments consisted of four pruning systems: Guyot, Guyot Arch, and Cazenave (cane pruning systems), and cordon spur pruning. Production, vine balance, and grape composition were evaluated. In the cane pruning systems, a mean production of 2.0 kg per plant and Ravaz index below 2 were observed, with no change in the composition of the berries. In spur pruned vines, there was production only in 2015, with four bunches every ten plants. Yield and production of the 'Nebbiolo' grapes can be increased without losses of oenological potential, in the high-altitude regions of Santa Catarina state. The tested cane pruning methods are indicated for the growing of 'Nebbiolo' because all methods confer similar yield and vigor to this grapevine.

The objective of the present work was to compare the effect of the training systems Y-trellis (Y) and Vertical Shoot Position trellis (VSP) on the production efficiency and chemical characteristics of grapes and wine from ‘Sauvignon Blanc’ cultivated in high altitude regions of Santa Catarina State, Brazil. The study was carried out in 2013, 2014 and 2015 harvests in a commercial vineyard located in the municipality of São Joaquim - SC (28º 17 ’38 ”S and 49º 55’54” O, altitude 1350 m). The obtained data were subjected to analysis of variance (ANOVA) with F Test (p ≤ 0.05). The relationship between the vegetative growth and the yield was influenced by the training system. For the ‘Sauvignon Blanc’ cultivar, the yield was 93% higher in the Y-trellis training system, resulting in better vegetative-productive balance. The technological and phenolic maturation of the grapes were similar in both training systems. The results of this study show that the Y-trellis training system is an alternative to use in Santa Catarina altitude regions because it provides an increased productivity on the ‘Sauvignon Blanc’ variety without compromising the composition of grapes, when comparing to the VSP training system.

The objective of this work was to evaluate shoot growth of the grapevine varieties Merlot and Cabernet Sauvignon, during 2006/2007, and Cabernet Sauvignon, during 2008/2009, in São Joaquim, SC, Brazil. The experiment was carried out in a commercial vineyard trained on a vertical trellis system. The shoots of the central part of the plants were selected, and the lengths from the base to the apex of 20 shoots per cultivar were evaluated. In 2006/2007, monitoring began at pruning, on 9/15/2006, and ended on 2/6/2007, totalizing 144 days of evaluation. During the 2008/2009 cycle, phenology and shoot growth for 'Cabernet Sauvignon' were assessed from grape development (1/13/2009) (pea-sized grapes) until shoot vegetative growth had ceased. Budburst occurred in the second half of September, and shoot-growth cessation occurred during ripening. Higher growth rates (about 4 cm per day) were observed in pre- and post-flowering, followed by reduction due to the competition for photosynthates for the formation of flowers and bunches. Temperature and photoperiod induce grapevine shoots to cease growth in the highland regions of Santa Catarina State, Brazil.

Rapid Drop

An “explosive extratropical cyclone” is an atmospheric phenomenon that occurs when there is a very rapid drop in central atmospheric pressure. This phenomenon, with its characteristic of rapidly lowering the pressure in its interior, generates very intense winds and for this reason it is called explosive cyclone, bomb cyclone. With gusts recorded of 116 km/h, atmospheric phenomenon – “cyclone bomb” (CB) hit southern Brazil on June 30, the beginning of winter 2020, causing destruction in its influence over. One of the cities most affected was Chapecó, west of the state of Santa Catarina. The satellite images show that the CB generated a low pressure (976 mbar) inside it, generating two atmospheric currents that moved at high speed. In a northwest-southeast direction, Bolivia and Paraguay, crossing the states of Parana and Santa Catarina, and this draft that hit the south of Brazil, which caused the destruction of the affected states.  Another moving to Argentina, southwest-northeast direction, due to high area of high pressure (1022 mbar). Both enhanced the phenomenon.

Os sistemas atmosféricos exercem um papel significativo no clima de uma região e poucos trabalhos determinaram os impactos dos sistemas atmosféricos no de­senvolvimento e na produção de videira. Os objetivos deste trabalho foram deter­minar a frequência de ocorrência dos sistemas atmosféricos durante o período da maturação à colheita da videira (Vitis vinifera L.) var. Cabernet Sauvignon para as duas regiões produtoras de Santa Catarina em diferentes safras e determinar a as­sociação entre a ocorrência dos sistemas atmosféricos e as regiões produtoras e as safras. Os sistemas atmosféricos foram identificados durante as safras de 2005/2006 à 2008/2009. Os municípios de Água Doce e Campos Novos foram escolhidos para re­presentar a região produtora 1 e os municípios de Bom Retiro e São Joaquim para re­presentar a região produtora 2. As frequências de ocorrências dos sistemas atmosfé­ricos durante o período da maturação à colheita de videira são muito semelhantes entre as regiões, somente houve diferença na frequência de ocorrência do sistema jato subtropical entre regiões. Houve uma diferença significativa da ocorrência da frequência dos sistemas atmosféricos entre safras.
