Special Issue Information

Dear Colleagues,

Viticulture and grapevine physiology are the core fields supporting the high-quality development of the grape industry. The production of high-quality grapes and the sustainable operation of the industry depend on a deep understanding of grape growth and development, as well as continuous innovation in cultivation technologies. Currently, climate change and recurring extreme weather events pose growing challenges to viticulture, making it imperative to innovate cultivation techniques and breed new stress-tolerant varieties. Additionally, the rapid advancement of biotechnology and molecular biology has brought new research perspectives and technical means to this field, driving us to make continuous breakthroughs in areas such as grape variety adaptability, stress resistance mechanisms, quality regulation, and efficient cultivation.

This Special Issue focuses on cutting-edge research in grape cultivation and vine physiology, aiming to gather innovative achievements and the latest insights from scholars worldwide. We sincerely welcome original papers (including reviews and research articles) covering growth and development regulation, environmental adaptability physiology, cultivation technology innovation, fruit quality formation mechanisms, and other related directions in grape research.

Accurate determination of endodormancy release is essential for grapevine dormancy management. However, most phenological models are validated only against macroscopic budbreak dates, without physiological verification of predicted release dates. Here, we integrated phenological modeling with biochemical profiling to characterize endodormancy release in two table grape cultivars with contrasting chilling requirements: ‘Muscat Hamburg’ (Vitis vinifera L.) and ‘Shine Muscat’ (Vitis labrusca × V. vinifera). Endodormancy release dates were determined by forced budbreak assays, and chilling and heat requirements were estimated from 5 min temperature records using the Dynamic Model and Growing Degree Hours. ‘Muscat Hamburg’ released endodormancy on December 16 (10.95 Chill Portions), whereas ‘Shine Muscat’ released on January 6 (22.78 CP). Around these dates, coordinated biochemical changes occurred in buds, including starch depletion, hexose accumulation, ABA decline, GA3 increase, and redox-related changes in H2O2 content and CAT activity. These changes were more pronounced in buds than in canes and were not identical across all biochemical indicators. Hydrogen cyanamide treatment induced biochemical changes similar to those observed during natural dormancy release, with cultivar-specific responses consistent across both conditions. These results indicate that experimentally determined endodormancy release dates are associated with population-level physiological changes, supporting the integration of phenological modeling with biochemical characterization in table grape production.
