To maximize the cutting rhizogenesis process, plant hormones, such as auxins, are used for the development of adventitious roots. In addition, some groups of biostimulant have as their main role the development of root system, ensuring good growth of the plant aerial part. However, research using algae extract-based biostimulants in vegetative propagation of vine rootstocks is scarce. In this sense, the objective of this work was to evaluate the use of the biostimulant based on algae extract and indolebutyric acid (IBA), in the development of the root system and vegetative growth of grapevine rootstocks. The rootstocks evaluated were ‘3309 C’, ‘101-14 Mgt’, ‘Paulsen 1103’, ‘99 R’, ‘110 R’, ‘Kober 5BB’, ‘SO4’, ‘420A Mgt’, ‘Solferino’, ‘Gravesac’, ‘IAC 572’, ‘IAC 766’, ‘IAC 313’, ‘Harmony’, ‘Freedom’, ‘Salt Creek’ and ‘VR 043- 43’. The experimental design was completely randomized with four replications, arranged in a factorial scheme, involving 17 rootstocks associated with four treatments to stimulate rooting (IBA, algae extract, IBA + algae extract and control). The use of indolebutyric acid and algae extract-based biostimulant proved to be efficient in rooting woody cuttings from different vine rootstocks. The use of IBA, algae extract-based biostimulant and IBA combined with algae extract resulted in higher rates of rooting and development than the control. The rootstocks presenting the highest rooting rates and vegetative development were ‘IAC 572’ and ‘Freedom’. ‘Gravesac’, ‘101-14 Mgt’ and ‘99 R’, showing high rates of rooting and root development, but low vegetative development. The rootstocks exhibiting the lowest rooting rates and vegetative development were ‘Salt Creek’, ‘VR 043-43’ and ‘110 R’.","PeriodicalId":54244,"journal":{"name":"Ciencia E Tecnica Vitivinicola","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"57873630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a key period during the wine’s evolution, with changes in the physicochemical and sensory characteristics, especially in the colour, aroma, flavour and mouthfeel. Traditionally, oak barrels have been the main vessel choice for the maturation period. However, due to new technology and increasing consumer interest, winemakers are now using different vessels which vary in material, shape and size to mature their wines. Despite this gain in popularity, there are key questions remaining regarding how exactly variations in maturation vessel physical parameters affect wine quality during maturation. This review summarises how variations to maturation vessel material, size, and shape influence wine quality, specifically regarding oxygen permeation, thermal conductivity, and the release of exogenous compounds. Overall, the vessel material and size have a significant influence over the oxygen transfer rate of the vessel, and the associated changes to colour, aroma and mouthfeel, which occur with oxygen ingress. Maturation vessels may be conceptually viewed on a scale of ‘inertness’, with more inert vessels, such as stainless-steel tanks, generally having higher thermal conductivity, lower oxygen transfer rate and less release of exogenous compounds, with the opposite being true for the more active vessels such as oak barrels. Finally, this review points out gaps in the literature such as how maturation vessel parameters influence lees-wine interaction. This review aims to lay out paths for future research needed to shed light on how maturation vessel choice affects wine quality.","PeriodicalId":54244,"journal":{"name":"Ciencia E Tecnica Vitivinicola","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135699491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While grapevine is considered a highly tolerant crop to several abiotic stresses, Mediterranean areas are frequently affected by adverse environmental factors, namely water scarcity, heat and high irradiance, and are especially vulnerable to climate change. Due to the high socio-economic value of this sector in Europe, the study of adaptation strategies to mitigate the negative climate change impacts are of main importance for its sustainability and competitiveness. Adaptation strategies include all the set of actions and processes that can be performed in response to climate change. It is crucial to improve agronomic strategies to offset the loss of productivity and likely changes in production and fruit quality. It is important to look for new insights concerning response mechanisms to these stresses to advance with more effective and precise measures. These measures should be adjusted to local terroirs and regional climate change projections for the sustainable development of the winemaking sector. This review describes the direct climate change impacts (on phenology, physiology, yield and berry quality), risks, and uncertainties for Mediterranean viticulture, as well as a set of canopy, soil and water management practices that winegrowers can use to adapt their vines to warmer and drier conditions.","PeriodicalId":54244,"journal":{"name":"Ciencia E Tecnica Vitivinicola","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"57873190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this work was to select the rootstock that confers the best productive performance to the ‘Vermentino’ variety, and to adjust the ideal spacing for this combination. The experimental design used was randomized blocks in a 5x3 factorial scheme, in which the treatments studied consisted of the combination of five rootstocks (‘101-14 Mgt’, ‘Harmony’, ‘IAC 572’, ‘Paulsen 1103’, and ‘VR 043-43’) and three spacings between plants (1.0, 1.2 and 1.5 m).

Bud break of ‘Paulsen 1103’ and ‘VR 043-43’ rootstocks occurred the latest in 2019/20 and 2020/21. ‘101-14 Mgt’ and ‘Paulsen 1103’ rootstocks induced the highest yields in 2019/20 and 2020/21. The 1.0 m spacing between plants provided the highest productivity in all seasons. Thus, it can be concluded that the ‘Paulsen 1103’ and ‘VR 043-43’ rootstocks delayed bud break and decreased phenological sub-periods. ‘Paulsen 1103’ and ‘101-14 Mgt’ rootstocks contributed to increase the productivity; the ‘IAC 572’ rootstock presented the lowest contribution to the polyphenols content and antioxidant activity, and the 1.0 m spacing between plants resulted in greater productivity of the vineyard.","PeriodicalId":54244,"journal":{"name":"Ciencia E Tecnica Vitivinicola","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"57873204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Grapes, peanuts, berries, cacao beans and red wine contain resveratrol. Resveratrol attracts attention due to its bioactive properties, however, the concentration of this compound is not high in grape and wine. Therefore, different studies have been carried out to increase resveratrol level in these products. Several factors such as the grapevine variety, the climatic conditions and the viticultural practices used to create stress on the vine affect the level of resveratrol. Winemaking technologies applied during pre-fermentation, fermentation and post–fermentation stages could also have an effect on the concentration of this stilbene. In addition, recent studies have evaluated biotechnological approaches through the use of different bacteria and yeast strains to produce wine with increased resveratrol content. In this review, the most important factors contributing to increase the resveratrol concentration in grapes and wines are examined.

However, some drawbacks associated with SO2 wine application led to the need to reduce or replace its use. In this work, VOCs profile after storage in bottle under different antioxidant conditions of two Portuguese monovarietal wines (‘Arinto’ and ‘Síria’) was studied. Wines were obtained by different winemaking environments (0, 50, 100 mg/L of SO2 and 100 mg/L ascorbic acid for ‘Síria’ and 15, 30, 45 mg/L of SO2 and 100 mg/L of ascorbic acid for ‘Arinto’ both with and without bentonite). After alcoholic fermentation, a second SO2 treatment was applied: 0 and 60 mg/L of SO2 to ‘Arinto’ wines and 30 and 60 mg/L of SO2 to ‘Síria’ wines. Wines were kept over lees for three months, bottled and analysed after three months in bottle. The VOCs present were analysed by HS-SPME-GC/MS six months after fermentation. The maturation conditions did not influence the evolution of free and total SO2. Regarding the VOCs profile evolution, the ANOVA analysis showed that esters are the most important group, presenting significant differences among samples. Through the PCA analysis, using wines after fermentation as reference, 74.13 % and 54.92 % of the variation were explained by the first two principal components for ‘Arinto’ and ‘Síria’, respectively. VOCs profile evolution of wines seems to be mainly influenced by the fermentation conditions.","PeriodicalId":54244,"journal":{"name":"Ciencia E Tecnica Vitivinicola","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"57873416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this work aimed to evaluate the impact of the use of an anti-hail net on the productivity and quality parameters of ‘Rose Niagara’ grapes grown in the region, in the 2019/2020 and 2020/2021 harvests. The studied parameters were production, number of bunches per plant, bunch length, berry diameter, mass of 100 berries, average bunch mass, juice pH, titratable acidity, soluble solids, phenolic compounds content, total anthocyanins content, and photosynthetically active radiation. The results showed that the anti-hail net influenced some quality parameters, but this change was not consistent in the two harvests, indicating a larger influence of edaphoclimatic conditions than of the use of the net. Thus, the anti-hail net may be an alternative to protect vineyards from hail and other bad weather conditions, without having important negative impacts on the production and quality of ‘Rose Niagara’ grapes.","PeriodicalId":54244,"journal":{"name":"Ciencia E Tecnica Vitivinicola","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"57873064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
