Published: Feb. 15, 2025

Rising soil salinity poses significant challenges to Mediterranean viticulture. While some rootstocks effectively reduce salt accumulation in grafted scions, the mechanisms and performance of novel remain largely unexplored. This study compared two M-series (M2, M4) with established commercial (1103 Paulsen, R110) evaluate their physiological responses tolerance under irrigation varying levels (0, 25, 50, 75 mM NaCl) over 5 months. Growth parameters, photosynthetic efficiency, chlorophyll content (SPAD), ion homeostasis, visual symptoms were monitored. Results revealed genotype-specific strategies: 1103 Paulsen exhibited robust efficiency exclusion, maintaining growth stability; M2 demonstrated superior biomass retention moderate compartmentalization but showed reduced at higher levels; R110 displayed effective management experienced reduction severe stress; M4 was most sensitive, reductions homeostasis. Organ-specific highlighted roots acting as primary reservoirs, particularly for sodium calcium; leaves high potassium chloride concentrations, critical photosynthesis prone ionic imbalance stems wood played a buffering role, compartmentalizing excess minimizing damage tissues.

Use of Biowaste for Sodium Removal in Mediterranean Irrigation Water: A Sustainable Approach

Clean Technologies, Journal Year: 2025, Volume and Issue: 7(1), P. 15 - 15

Published: Feb. 7, 2025

The Mediterranean region faces significant water scarcity, a challenge intensified by climate change, impacting both agricultural productivity and quality. High sodium levels in irrigation compromise soil structure, leading to reduced crop yields economic strain. This study investigates the use of sustainable adsorbents derived from residues (almond shell, eggshell, pumice) for removal water. These materials, widely available Mediterranean, support circular economy principles repurposing biowaste address challenges. Adsorption experiments were conducted using real water, capturing complexity its physicochemical properties evaluate effectiveness these biosorbents under practical conditions. A Central Composite Rotational Design (CCRD) was applied optimize adsorption parameters, focusing on adsorbent concentration, agitation, contact time. Kinetic studies indicated that adhered pseudo-second order model, suggesting chemically controlled process. Isotherm analysis, with strong fit Jovanovic confirmed predominantly monomolecular mechanism across all adsorbents, while Freundlich model highlighted site heterogeneity. Microscopy energy-dispersive X-ray spectroscopy (EDX) revealed structural modifications before after treatment. porous internal structure almond shell displayed retention, calcified eggshell surface showed high initial efficiency but rapid saturation. Pumice, noted extensive porosity, sustained capacity even deposits formed during research demonstrates potential biowaste-derived efficient complex aqueous systems, offering viable solution agriculture improved management regions.

Evaluation of Commercial Tomato Hybrids for Climate Resilience and Low-Input Farming: Yield and Nutritional Assessment Across Cultivation Systems

Agronomy, Journal Year: 2025, Volume and Issue: 15(4), P. 929 - 929

Published: April 10, 2025

Commercial tomato hybrids exhibit robust performance in modern high-input agricultural systems. However, their suitability for low-input farming remains uncertain. With the goal that by 2030, 25% of European production must be organic as part Green Deal, this study aims to assess whether existing commercial can offer a viable solution farming. Additionally, impact beneficial microorganisms such plant growth-promoting rhizobacteria (PGPR), relation growth and productivity under cultivation is assessed. For purpose, well-defined microbial consortium, including Azotobacter chroococcum, Clostridium pasteurianum, Lactobacillus plantarum, Bacillus subtilis, Acetobacter diazotrophicus, was applied liquid suspension enhance root colonization promote growth. Seven tomatoes (Solanum lycopersicum L.) hybrids—the most popular Greek market—were evaluated (hydroponic) systems (with without use PGPR). Several parameters related yield, fruit quality, nutritional value, descriptive traits, leaf elemental concentration were evaluated. In addition, techno-economic analysis conducted developed conditions intended environments suit The results indicated are not viable, efficient, or profitable strategy cultivation. These findings underscore importance breeding varieties, specifically adapted farming, highlighting need targeted strategies sustainability resilience future Notably, among first comprehensively response conditions, addressing critical gap current literature.

Surveying consumer preferences for eco-labeled fruits and vegetables in Euro-Mediterranean alternative food systems

Frontiers in Sustainable Food Systems, Journal Year: 2025, Volume and Issue: 9

Published: May 6, 2025

The growing environmental challenges in Mediterranean fruit and vegetables production, including water scarcity, soil degradation, biodiversity loss, have led to increased interest alternative food systems as a pathway sustainable agriculture. However, significant research gap remains understanding consumer preferences for eco-labeled within these systems, particularly comparison conventional supply chains. Short chains emphasize local engagement, transparency, reduced impact, whereas export-oriented prioritize large-scale production global market but face concerns regarding their implications. This study addresses this by analyzing the key drivers influencing willingness pay short chains, providing novel insights into decision-making across different chain structures. Specifically, it investigates how consumers two differ attitudes toward eco-labels, focusing on label information, concerns, trust certifications. Using data from an online survey conducted June 2023 Italy, France, Greece with final sample of 1,163 respondents, follows two-step approach. First, one-way analysis variance is used assess differences consumers' eco-labels between Second, partial least squares structural equation modeling estimate relationships identifies vegetables. results show that certifications emerges strongest predictor both especially Interest information also plays role contexts, while are more relevant Younger exhibit stronger vegetables, education levels no effect. highlights distinct roles shaping preferences. foster through engagement reducing need formal certifications, rely due industrialized impersonal nature.

Societal Impact Statement Viticulture is facing increasing challenges due to climate change. The focus on fast growth and sweet berries has come at the expense of stress resilience. Grafting onto Phylloxera‐resistant rootstocks from American species been most successful form ecological pest management. However, there still a significant reliance chemical plant protection. Additionally, abiotic not primary concern in rootstock breeding efforts so far. To identify genetic factors that contribute tolerance, we propose explore potential wild ancestor grapevine, Vitis sylvestris . By identifying resilience factors, can develop new generation or enhance grafted cultivars protect viticulture impact constraints. Summary There an urgent need germplasm resources for traits tolerance grapevines. posed by change, including heat drought stress, salinity, rising temperatures, untimely cold snaps spring, are intensifying. Traditional grapevine varieties often lack withstand environmental threats because conventional historically prioritized yield flavor over tolerance. In this review, highlight European Wild Grapevine, , as valuable resource traits. Understanding underlying mechanisms crucial developing molecular markers support breeding.
