Abstract Grape (Vitis vinifera L.) cultivation has progressed from early domestication and clonal propagation to modern, data-driven breeding that is reshaping viticulture and wine quality. Yet climatic and biotic constraints still impose heavy losses—downy mildew can reduce yields by ≈75% in humid regions and gray mold by 20–50%—sustaining the need for resistant cultivars. Producer selection, interspecific crossing, and formal improvement programs have generated ~10,000 varieties, although only a few dozen dominate global acreage. Conventional breeding has delivered fungus-resistant “PIWI” cultivars that retain ≥85% of the V. vinifera genome; in Austria, national PIWI varieties are gaining acceptance for combined… More >

Abstract Climate change-driven environmental stresses, particularly ultraviolet-B (UV-B) radiation, pose severe threats to grapevine (Vitis vinifera L.) productivity and physiological stability. This study investigated the protective role of melatonin in in vitro plantlets of two grapevine cultivars, ‘Merlot’ and ‘Erciş’, subjected to low (≈8.25 μW cm⁻², 16 h) and high (≈33 μW cm⁻², 4 h) UV-B exposure. Significant cultivar-specific responses were observed (p < 0.001). The ‘Erciş’ cultivar exhibited higher oxidative stress, with malondialdehyde (MDA) levels reaching 24.30 mmol g⁻¹ FW in control plants compared with 14.91 ± 0.25 mmol g⁻¹ FW in ‘Merlot’. Melatonin provided dose-dependent mitigation, reducing MDA to… More >

Abstract Grapevine (Vitis vinifera L.) is one of the main crops worldwide, and ultraviolet-B (UV-B, 280–315 nm) radiation is emerging as a promising technical tool to enhance secondary metabolites that can contribute to the quality and health-promoting properties of both grapes and the resulting wines. However, few studies have assessed the effectiveness of UV-B supplements under field conditions. Here, we compared the effects of two different field UV-B treatments (a single supplement applied at pre-harvest, and a double supplement applied at both veraison and pre-harvest) on the phenolic composition of Tempranillo grape skins and the resulting wines.… More >

Abstract In recent years, fungal diseases affecting grape crops have attracted significant attention. Currently, the assessment of black rot severity mainly depends on the ratio of lesion area to leaf surface area. However, effectively and accurately segmenting leaf lesions presents considerable challenges. Existing grape leaf lesion segmentation models have several limitations, such as a large number of parameters, long training durations, and limited precision in extracting small lesions and boundary details. To address these issues, we propose an enhanced DeepLabv3+ model incorporating Strip Pooling, Content-Guided Fusion, and Convolutional Block Attention Module (SFC_DeepLabv3+), an enhanced lesion segmentation method based… More >

Abstract The reproduction of grapevine genotypes, one of the most important species in the world, while preserving their genetic characteristics, is practically done by rooting cuttings. Adventive rooting of cutting studies for seedling production in nursery conditions often remain below the expected productivity level due to biotic and abiotic stress-related reasons. Studies to increase nursery yields are still on the agenda of grapevine researchers. In this study, the effects of silver nanoparticles (AgNPs) produced by the green synthesis method using grape seed extract and AgNO₃ on rooting and vegetative growth of the standard (TS 4027) cuttings taken… More >

Abstract The search for environmentally friendly approaches in viticulture is increasing, driven by the need to minimize the ecological footprint of conventional methods while ensuring high grape quality and stable yields. Among the various alternatives explored, essential oils (EOs) have drawn attention due to their natural origin and bioactive properties, including antimicrobial, antifungal, and insect-repellent effects. They are characterized by numerous utilisations, from managing diseases and pests in vineyards to post-harvest applications to preserve and prolong storage duration. This innovative review examines, for the first time, the topic of EOs on viticulture, embracing their multiple uses… More >

Abstract Biochar has emerged as a promising tool for enhancing vineyard sustainability by improving soil properties and mitigating climate change impacts. This review highlights key findings on biochar’s role in viticulture, focusing on its effects on soil fertility, water retention, and plant physiology. Field and pot studies demonstrate that biochar amendments enhance soil structure, increase cation exchange capacity (CEC), and promote water availability, leading to improved drought resistance in grapevines. However, the impacts on grape yield, physiology, and quality remain inconclusive, with some studies reporting benefits while others show neutral effects. Future research should focus on More >

Abstract This study simplifies the complex relationship among grapevine plants, aphids, ladybirds, and ants, which is essential for effective pest management and ecological balance. This study investigated the impact of aphid attacks and the presence of ants and ladybirds on the volatile compounds profile released into the chemosphere of the community consisting of the common vine Vitis vinifera, the aphid Aphis illinoisensis, the ladybird Coccinella undecimpunctata-and the ant Tapinoma magnum. This study aims to analyze the volatile compounds emitted by the grapevine and surrounding insects in response to these intricate interactions. The extraction of volatile organic compounds (VOCs) was carried… More >

Abstract Grapes, one of the oldest tree species globally, are rich in vitamins. However, environmental conditions such as low temperature and soil salinization significantly affect grape yield and quality. The glutamate receptor (GLR) family, comprising highly conserved ligand-gated ion channels, regulates plant growth and development in response to stress. In this study, 11 members of the VvGLR gene family in grapes were identified using whole-genome sequence analysis. Bioinformatic methods were employed to analyze the basic physical and chemical properties, phylogenetic trees, conserved domains, motifs, expression patterns, and evolutionary relationships. Phylogenetic and collinear analyses revealed that the VvGLRs… More >

Abstract The vascular system of the grapevine (Vitis vinifera L.) flower is a channel for transporting water and nutrients to the ovary. It plays an important role in the development of the ovary and fertilization through pollination. However, the vascular bundles in the flower are so tiny that they are difficult to sample and observe by traditional slicing techniques. In this study, ‘Summer Black’ grape flowers were selected as the test materials, and the tissue samples were treated by the optical clearing technique. After simple compaction, the structure and development of the vasculature were observed by common… More >
