Special Issue Information

Dear Colleagues,

Sustainability in table grape production has become an increasingly critical area of focus as global demand for these fruits continues to grow. Producers are adopting innovative practices that minimize their environmental impact while ensuring economic viability and social responsibility. A cornerstone of sustainable table grape production is the efficient use of natural resources. This includes implementing advanced irrigation systems like drip irrigation, which minimizes water waste, and utilizing soil moisture sensors to optimize watering schedules. By reducing excessive water consumption, these practices not only conserve resources but also enhance the health and productivity of vineyards.

Another significant aspect of sustainable practices is the reduction of the chemical inputs used in grape production. Integrated pest management (IPM) strategies have gained prominence, combining biological controls, such as the use of beneficial insects, with minimal chemical interventions to manage pests and diseases. Additionally, organic farming practices, including the use of compost and green manure, enrich soil fertility without relying on synthetic fertilizers. These approaches contribute to preserving biodiversity, improving soil health, and ensuring the production of safer, chemical-free grapes.

In addition to resource management, the breeding of table grapes plays a crucial role in advancing sustainability. Modern breeding programs focus on developing grape varieties that are resistant to pests and diseases, such as downy mildew and powdery mildew, reducing the need for chemical pesticides. Varieties bred for drought tolerance also enable production in water-scarce regions, conserving precious resources. Furthermore, breeding efforts aim to enhance traits related to fruit quality, such as sweetness, seedlessness, and extended shelf life, catering to consumer preferences while reducing food waste in the supply chain.

Beyond environmental concerns, sustainability in table grape production also addresses social and economic factors. Fair labor practices, worker training programs, and community engagement initiatives ensure that grape production benefits local populations. Moreover, producers are increasingly incorporating renewable energy sources, such as solar power, into their operations to reduce their carbon footprint. The integration of these multifaceted sustainability practices not only supports the long-term viability of the industry but also aligns with the growing consumer preference for environmentally and socially responsible products.

In this new Special Issue “10th Anniversary of Horticulturae: Sustainable Practices in Table Grape Production, authors are welcome to submit original papers and reviews and to share their achievements in this subject.

Understanding the effects of edible coatings on postharvest quality and shelf life of ‘Karaerik’ grapes is crucial for improving storage outcomes and reducing losses. However, limited information exists regarding the effectiveness of different coating materials on this regionally significant variety. In this study, ‘Karaerik’ grapes were treated with carboxymethyl cellulose (CMC) and locust bean gum (KB) coatings and stored under cold conditions (0 ± 0.5 °C, 90–95% relative humidity) for 0, 25, 45, and 60 days. Storage duration and coating treatments significantly affected most physical, physiological, and biochemical parameters. During storage, grape weight loss progressively increased, reaching 9.60% in the control by day 60. Coatings slightly reduced this loss, with KB showing the lowest (5.11%) compared to the control (5.69%). Respiration initially declined but surged again at day 60, especially in the control (96.4 μmol CO2/kg·hour), while coatings helped mitigate this rise. Ethylene release remained unchanged. A slight pH decline (~4.6%) was observed in the control, while KB-treated grapes maintained higher pH and lower acidity. Soluble solids remained stable across treatments. Color changed notably during storage: a* nearly doubled (more redness), b* increased (less blue), and chroma (C*) declined by ~25%, especially in uncoated grapes. Total sugar dropped by ~43% in KB-treated grapes, with the control retaining the most. Tartaric acid decreased by ~55%, notably in KB samples. Antioxidant activity and total phenolics declined significantly (~66%) in the control. CMC coating better-preserved antioxidant capacity, while the control showed the highest phenolic levels overall. Ferulic, gallic, and chlorogenic acids increased toward the end of storage, particularly in coated grapes. In contrast, rutin and vanillic acid peaked mid-storage and were better preserved in the control. The heatmap showed significant metabolite changes in fruit samples across 0D, 25D, 45D, and 60D storage periods under CMC, CNT, and KB treatments, with distinct clustering patterns revealing treatment-specific biochemical responses. The correlation matrix revealed strong positive relationships (r > 0.70) between total sugar, glucose, and fructose levels, while ethylene showed significant negative correlations (−0.65 to −0.85) with maturity index, pH, and total soluble solids, indicating interconnected metabolic pathways during fruit ripening and storage. We conclude that edible coating selection significantly influences grape biochemical stability during cold storage, with CMC emerging as a superior choice for maintaining certain quality parameters.
