Abstract Water saving under drought stress is assured by stomatal closure driven active (ABA-mediated) and/or passive (hydraulic-mediated) mechanisms. There currently no comprehensive model nor any general consensus about the actual contribution and relative importance of each above factors in modulating planta . In present study, we assessed (hydraulic) vs (ABA mediated) mechanisms V. vinifera plants facing stress. Leaf gas exchange decreased progressively to zero during embolism-induced...
Grapevine (Vitis vinifera L.) is an economically important crop with a wide geographical distribution, reflecting its ability to grow successfully in range of climates. However, many vineyards are located regions seasonal drought, and these often predicted be global climate change hotspots. Climate affects the entire physiology grapevine, strong effects on yield, wine quality typicity, making it difficult produce berries optimal enological consistent stability over forthcoming decades. Here...
One of several challenges in cool climate viticulture with a short growing season is to consistently reach uniform, optimal fruit technological maturity at harvest before the first autumn frost. Weather conditions Michigan from veraison are highly variable and unpredictable among years, constraining preharvest assessment quality for grapegrowers wineries. Under these environmental conditions, cluster thinning leaf removal commonly adopted viticultural techniques enhance ripening. Cluster...
The influence of pruning date on yield control and ripening rate spur-pruned Sangiovese grapevines was investigated over two years (2013 2014). Winter applied 1 or 4 Feb (mid dormancy); 5 March (late 2 7 April (bud swell); May (flowers closely pressed together); 6 June (40 to 50% flower caps fallen), respectively. Vine fruit composition at harvest were not affected by shifting from the standard dates mid late dormancy bud swell stage. In contrast, number inflorescences in compound buds...
Sangiovese vines mechanically spur-pruned during dormancy in February were manually finished either immediately or post budburst to test the potential of a 'double-pruning' approach delay fruit sugar accumulation and limit yield. The treatments applied 2014, 2015, 2016 at BBCH-0 as standard hand-finishing on dormant buds (SHF), late (LHF) very (VLHF) BBCH-14 BBCH-19, i.e., when two apical shoots mechanically-shortened canes ~10 20 cm long, respectively. While yield per vine was drastically...
Recent studies report that Ascophyllum nodosum extracts, once applied on the canopy of different crops, deliver positive effects, increasing yield, inducing tolerance to biotic stress, and improving quality products. However, mechanisms action are still unclear. In this research, vines subjected multiple foliar applications an A. extract (ANE) at label doses were compared with untreated (NTV) in accordance a comparative approach. The investigation coupled field experiment second trial...
Even though mechanization has dramatically decreased labor requirements, vineyard management costs are still affected by selective operations such as winter pruning. Robotic solutions becoming more common in agriculture, however, few studies have focused on grapevines. This work aims at fine-tuning and testing two different deep neural networks for: (i) detecting pruning regions (PRs), (ii) performing organ segmentation of spur-pruned dormant The Faster R-CNN network was fine-tuned using...
Superabsorbent Hydrogels are materials capable of absorbing significant amounts water as compared to their mass. In view climate change constraints, the use new is gaining interest, but little known about effects on tree physiology when incorporated at transplanting. The goal work was determine incorporation a potassium polyacrylate based Hydrogel soil (SH) potted grapevines, modeling physiological answer untreated Controls (CON). We aimed understand if could benefit plant status and...
The success of double cropping in Vitis vinifera L. cultivated temperate climates relies on bud forcing efficiency, which requires the prompt unlocking apical dormant buds with sufficient fruitfulness. Chemical dormancy-breaking strategies need to be tested enhance summer pruning, as hydrogen cyanamide, most used agent, could damage green organs. This study whether foliar applications cytokinins and auxins modulate dormancy release, potentially affecting dynamics shoot treatments involved...
A better physiological and productive performance of cv. Montepulciano versus Sangiovese under well-watered conditions has been recently assessed. The objective this study was to verify that behaviour is maintained when a pre-veraison deficit irrigation (vines held at 40% pot capacity from fruit-set veraison) followed by re-watering (pot reported 90%). Single leaf assimilation rate stomatal conductance, diurnal seasonal whole-canopy net CO2 exchange (NCER) water use efficiency were always...
Malate is accumulated in grape pericarp until the start of ripening and then it dissimilated. One aim this study was to determine if potential contribution stored malate substrate requirements metabolism dependent on cultivar. Two Vitis vinifera L. cultivars which different amounts had periods a length were compared. The over whole period around 20 % cv. Sagrantino 29 Pinot Noir. higher Noir because contained more shorter period. A second evaluate gluconeogenesis amount sugar pericarp. If...
Background and Aims The postponement of spur pruning after budburst has recently been proposed as a simple inexpensive way to delay sugaring, maintain acidity contain yield in spur-pruned trellised grapes. Yet, no long-term data are available for the widely adopted cane system. Methods Results Mature field grown Vitis vinifera L. cv. Pinot Noir vines were subjected three consecutive years following treatments: standard winter (WP), double (DP), where shortening positioning selected is...
Removal of basal leaves near blooms inevitably affects grapevine balance and cluster microclimate conditions, improving fruit quality. Mechanization this practice allows growers to save time resources, but our knowledge, it has not yet been compared with the manual application in a cool-climate region where seasonal temperatures frequently limit technological maturity phenolic ripening red Vitis vinifera cultivars. In research, berry sugar concentration was highest prebloom mechanical...
In many viticulture regions, multiple summer stresses are occurring with increased frequency and severity because of warming trends. Kaolin-based particle film technology is a technique that can mitigate the negative effects intense and/or prolonged drought on grapevine physiology. Although primary mechanism action kaolin increase radiation reflection, some indirect protection canopy functionality faster stress recovery by abscisic acid (ABA) regulation. The physiological underlying...
Early leaf removal significantly alters the source-sink balance within grapevine shoots, leading to a reduction in fruit set. However, no research has previously examined conditions controlling this process terms of carbon allocation among major sink organs following defoliation. In study, impact defoliation at bloom on distribution dynamics assimilates clusters and growing shoot apices was investigated Vitis vinifera, cv. Pinot noir, grown Michigan, cool climate viticultural region. Three...
