The effects of six alternative wood species – sweet chestnut, common hazel, <i>Robinia</i>, blackcurrant, vineyard peach, and grapevine – on Austrian <i>Vitis vinifera</i> L. cv. Grüner Veltliner wine were examined after a 98-day contact period using both toasted and untoasted wood chips. The aim was to characterise the similarities of these alternative wood species to traditionally used oak. A comprehensive analytical profiling was conducted, quantifying over 50 wood-associated compounds, including hydroxycinnamic and benzoic acids, ellagitannins, lactones, carbonyl compounds and volatile phenols. Currently, only oak and sweet chestnut are approved by the International Organisation of Vine and Wine for oenological applications, with wood chips permitted exclusively from the genus <i>Quercus</i>. Based on the results, toasted sweet chestnut was the most promising alternative species for use as wood chips. It enhanced the wine colour intensity more effectively than oak, while its phenolic composition, particularly catechin levels and hydroxycinnamic acids, aligned moderately with oak. Furthermore, wine treated with toasted sweet chestnut presented comparable concentrations of vescalagin and castalagin. The similar levels of carbonyl compounds, such as furfural, further underlined its suitability. Although volatile phenol levels, including vanillin, exceeded those of oak, wine treated with toasted sweet chestnut remained comparable in its overall composition. Based on these findings, toasted sweet chestnut is recommended for approval as wood chips, although additional sensory and toxicological studies are necessary to substantiate this recommendation.</p>\u0000 </div>","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2025 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/ajgw/6622763","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, reviews of the scientific literature have become more effective through the use of meta-analyses, which are systematic evaluations of the results from multiple studies.

In the framework of a collaborative methodology between different Spanish viticultural research groups, this work uses a mega-analytical approach to quantify the effects of changes in vine water status on vine vegetative growth, yield, and grape composition, integrating a wide range of growing conditions to obtain robust general trends of vine performance under water deficit. The mean seasonal stem water potential data from the different studies allowed a classification into five levels of water status (no deficit ⟶ mild ⟶ moderate ⟶ high ⟶ severe). A progressive decrease in vegetative growth with increasing deficit was observed, while yield decreased more markedly as water deficit progressed from moderate to high. On the other hand, titratable acidity was more sensitive to variation in water status than sugar concentration, with a greater decrease in titratable acidity when changing from no to moderate deficit. Conversely, increasing water deficit from moderate to high resulted in the greatest increases in grape anthocyanin in the red varieties explored. The results obtained in this work provide solid information on general trends in grapevine response to water deficit that can be used in simulation models or incorporated by grape growers in their decision-making processes in relation not only to irrigation management but also on other agronomic tools to impact grapevine water status.</p>\u0000 </div>","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2025 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/ajgw/1588228","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated the effects of two novel termination practices—interrow rolling (R) and subrow mulching (SRM)—on vine performance and physiology of Barbera grapevines over 3 years, comparing them to a standard termination practice (green manuring, GM) and a control (C) consisting of alternated tilled and vegetated interrows. For each termination type, we used a cereal-based (Humusfert, H) and a more balanced (Stratus, S) seed cocktail. Data collection included CC biomass, seasonal soil and leaf water potential, leaf assimilation (A) and stomatal conductance (<i>g</i><sub><i>s</i></sub>) rates, vine vigor, yield, and grape composition at harvest. R caused a 31% reduction in pruning weight compared to C. Soil water potential at 30-cm depth, as well as leaf A and <i>g</i><sub><i>s</i></sub>, was more limited than in the other treatments and, in S-R, ripening was delayed. R performances might suffer from increased surface evaporation and reduced precipitation effectiveness due to the thick mulch layer. Both SRM treatments ensured a thick mulch layer (over 1 kg of desiccated grass/m<sup>2</sup>), which effectively controlled weeds when placed under the row. SRM did not impact vine vigor and yield; however, using the S mix slightly delayed final ripening. The presence of a thick, dead mulch layer under the row improved soil water potential (Ψ<sub>SOIL</sub>) at 30- and 60-cm depths compared to all remaining treatments that shared a mowed under-the-trellis strip. Seasonal dynamics of absolute Ψ<sub>SOIL</sub> show that when Ψ<sub>SOIL</sub> in the C plot fell below −0.2 MPa, Ψ<sub>SOIL</sub> was significantly higher (less negative) in H-SRM than in S-SRM. This was also associated with average reductions of 31.3% and 37.1% in A and <i>g</i><sub><i>s</i></sub> rates in S-SRM compared to H-SRM, respectively. The higher fresh biomass yielded by the more balanced mix (S) may relate to increased soil water depletion, especially during the pre-termination phase. Both C and GM treatments showed similar vine performance; however, C was significantly limited in leaf gas exchange compared to others. C does not benefit from any mulching effect, and a competitive native grass cover persists every second interrow during the dry and harsh summer season.</p>\u0000 </div>","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2025 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/ajgw/4271832","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The efficiency of the vine canopy, particularly in terms of gas exchange and net assimilation, declines with water scarcity, underscoring the importance of mitigating strategies such as emergency irrigation. However, in Mediterranean vineyards, water shortages often render irrigation impractical. An alternative approach is the application of minerals, such as zeolites, to mitigate the negative effects of summer stress. This study aimed to evaluate the physiological, vegetative–productive, and qualitative effects of chabazite-rich zeolite treatments on potted grapevines subjected to both water and heat stress, and on field-grown vines exposed only to heat stress. The research was conducted over a 3-year period (2021–2023) on Sangiovese grapevines, divided into two distinct trials: the first on potted vines (2021) and the second on field-grown vines (2022–2023). The potted trial involved 12 plants placed on lysimeters, subjected to water restriction (50% restitution of water lost through transpiration), and divided into two treatments: water stress vines (WS) and WS vines treated with natural zeolite (WS + ZEO). The field trial involved 24 nonirrigated plants with two treatments: untreated control (WS) and zeolite treatment (WS + ZEO). Microclimatic conditions were monitored during ripening, and the effects of zeolite were assessed in terms of canopy physiology, yield, sunburn damage, and grape composition. Grapes from the field trial vines were microvinified, and the resulting wine color was analyzed twice, after 3 months and 1 year. The results showed that zeolite treatments effectively reduced canopy temperature by two degrees Celsius, enhancing gas exchange efficiency and photosynthetic activity in potted vines. In field-grown vines, these treatments significantly improved grape composition, particularly boosting total anthocyanin levels by 19% in the berries and 10% in the resulting wine, compared to the untreated control.

The aim was to study the impact of different pruning severity treatments [16, 24 and 32 bud m<sup>−1</sup> of productive cordon and simulated mechanical pruning (SMP)] on the performance of a Malbec SHW vineyard in a hot and arid region.</p>\u0000 <p><b>Methods and Results:</b> The vineyard performance was assessed by means of characterizing the canopy architecture, winter trunk reserves, yield, fruit and wine composition. The variation of the pruning severity affected the architecture of the shoots but did not affect the canopy total leaf area. Lower pruning severity levels increased the number of smaller shoots and decreased the proportion of the leaf area corresponding to secondary shoots. After 3 years of treatment, bud fruitfulness and winter wood reserves were not adversely affected by lowering pruning severity. In general, it was observed that the lower the pruning severity, the higher the yield. Indeed, the lowest pruning severity level (SMP) increased the number of smaller clusters with fewer and smaller berries.

Most of this difference was due to increased fungal biomass in the vineyard (53% more total fungi biomass, <i>p</i> &lt; 0.001), including mycorrhizal species (159% more mycorrhizal fungi biomass, <i>p</i> &lt; 0.001). The study deployed a series of 10 electronic noses, each with six different gas sensors, on both sets of soil. The electronic noses detected higher levels of volatile organic compounds from the vineyard soil (<i>p</i> &lt; 0.001), thus establishing a strong positive correlation with the microbial biomass results.</p>\u0000 </div>","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2025 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/ajgw/4224202","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Damaged trunk wood samples presented a larger damaged section (DS) than that in branch wood samples. The compressive strength × DS interaction yielded significant differences, which suggest a stronger relationship between DS and loss of resistance in branches. Both loading (Time 1) and breakage (Time 2) times decreased as DS increased for branch wood samples (fresh and dry); however, significant differences were observed in Time 2, suggesting that, in branches, DS causes greater fragility. Maximum bending moment was higher in undamaged branch wood samples than that in damaged ones (dry or fresh); this demonstrates that undamaged wood fibers are less resistant than those attacked by <i>X. arvicola</i> larvae.</p>\u0000 <p><b>Conclusions:</b> The grape weight and/or the vibration applied by harvesting machines in affected wood branches can produce production losses and cause serious economic losses to the wineries or owners of the affected vineyards and, therefore, could be recommended to remove annually the affected parts to avoid the accumulation of dead wood due to the ingestion of its vascular tissues at the first insects attacks.</p>\u0000 </div>","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2025 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/ajgw/1069408","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143370084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
