Moreover, no modulation of genes related to defense, growth, and secondary metabolism was found in the leaves of DVS-treated plants, indicating no negative impacts of VMD on grapevine physiology. The only observed difference associated with DVS treatment was an increased internodal length under field and greenhouse conditions with partial stimulation of shoot length.

This study is the first to investigate the enrichment of Cabernet Sauvignon wine with <i>Arthrospira platensis</i> (AP), a filamentous cyanobacterium, to improve its nutritional and functional attributes. Grapes harvested from Gaziantep Province (Türkiye) in 2022 were used to produce four wine variants: a control (0% AP) and three treatments with 0.1%, 0.2%, and 0.4% AP. AP addition significantly affected physicochemical properties, bioactive composition, and sensory attributes. AP-enriched wines exhibited a gradual increase in pH over time, unlike the control. Total phenolic content rose sharply after opening, reaching 4107.9 mg·GAE/L in the 0.4% AP wine, while the control declined. Antioxidant capacity improved, with the highest DPPH radical scavenging activity (6.12 mg·TE/mL) in the 0.4% AP treatment. Concentrations of key phenolics—including gallic acid, resveratrol, quercetin, procyanidin, and chlorogenic acid—were significantly elevated. Principal component analysis further distinguished AP wines from the control, highlighting AP’s role in altering wine composition. Sensory evaluation revealed that 0.1% AP improved flavor, aroma, appearance, and color, whereas higher levels slightly reduced acceptance due to intense pigment and aroma characteristics, though scores remained within acceptable limits.

Nevertheless, our knowledge about the optimal water management in mountain vineyards remains limited. This study evaluated the effect of drought stress on two grapevine cultivars (Sauvignon Blanc and Chardonnay) under irrigated and rainfed conditions. The research took place in the mountainous region of South Tyrol in northern Italy. Soil-water status, several plant-based physiological stress indicators, yield components, berry quality, and wine sensory attributes were monitored across two growing seasons. Drought stress varied in timing and intensity. In 2021, a 10-day drought occurred during berry set, while in 2022, a more severe drought coincided with veraison and was combined with a 9-day heatwave. Reduced soil-water availability caused growth inhibition and impaired photosynthetic activity, particularly in 2022. Conversely, the mild to moderate water deficit during berry set caused a greater reduction in berry size and weight, and consequently in yield, than the more severe water deficit at veraison. As for berry quality traits, drought stress affected berry soluble solids accumulation, but not pH or titratable acidity. Furthermore, sensory analysis revealed distinct differences across vintages and cultivars. Wines from rainfed vines displayed enhanced hedonistic attributes (e.g., complexity, fullness, and length), particularly when the stress occurred early during the season. Generally, despite comparable stress exposure, Sauvignon Blanc vines were more drought-sensitive, showing greater growth inhibition, decreased photosynthetic activity, substantial yield loss, and altered wine sensory profiles. Chardonnay, conversely, seemed more resilient to drought conditions, showing no discernible differences between rainfed and irrigated wines. In conclusion, this study reveals varying levels of drought tolerance between the two cultivars across two seasons. These findings may help develop cultivar-specific irrigation schedules for mountain vineyards, enhancing water conservation, preserving yields, and ultimately achieving the desired wine quality.</p>","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2026 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/ajgw/6920071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145941563","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 forced crop was achieved by breaking bud dormancy through severe trimming at the groat-size berry stage; retaining four, six or eight main leaves on the shoot (F4, F6, F8); and concurrently removing any developing laterals. These treatments were compared to an unforced control (C). Vine performance was assessed through phenology, vegetative growth, yield components, vine balance indices and grape composition at harvest. In the 2022–2023 season, the response to forcing was faster (13 days) and more active (0.69 forced shoots/total shoots) than in the 2023–2024 season (19 days and 0.47 forced shoots/total shoots, respectively). Reactivity to forcing tended to decrease at F8 compared to F4 and F6. On average, the forced leaf area (LA) constituted 59.2% of the total LA. Across all F treatments, the total yield per vine was 11.6% higher than C, with the forced crop contributing 36.1% of the total yield. Forced shoot bunches were consistently smaller and looser than those on the P shoots and harvest of the second crop occurred 56–60 days later. Forcing significantly delayed the ripening of the primary crop compared to the control, yet fruit in F treatments reached a relatively high TSS (23.7–24.1°Brix) while maintaining higher TA and lower pH, indicating a desynchronisation of sugar and acid ripening. Seasonal variation strongly influenced anthocyanin and phenolic accumulation: in 2022–23, levels were highest in F treatments, even compared to the control; in 2023–2024, they were comparatively low.

Furthermore, the dominant bacterial genus <i>DMER64</i> and fungal genus <i>Orbilia</i>, both present in KWW, were recruited to colonize grapevine tissues, potentially promoting plant growth and physiological processes. Overall, the KWW sludge demonstrated multiple suppressive actions, such as the release of humic substances and biochemical compounds, which facilitate the recruitment of beneficial microorganisms in response to latent <i>L</i>. <i>brasiliensis</i> infection. These findings suggest that KWW is a promising alternative for managing grapevine pruning waste, effectively reducing GTD pathogen transmission while enhancing beneficial endophytic communities.</p>","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2025 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/ajgw/6677698","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145407099","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}
