Special Issue Information

Dear Colleagues,

Abiotic stresses are the most challenging environmental factors that affect global vegetable crop production. Abiotic factors, such as high and low temperatures, drought, flood, salinity, radiation, etc., affect crop growth and enable the infestation of insect pests and diseases, resulting in drastically reduced yields and production under certain conditions. These stress stimuli do not act in isolation but often occur simultaneously. Thus, understanding crops’ physiological changes and adaptability in response to multi-stress stimuli and exploring appropriate measures to address these issues are crucial for vegetable farming.

Of possible measures, strengthening genetic-based tolerance and agronomy practices are plausible approaches for mitigating the adverse effects of environmental stressors and for improving crop resilience and productivity. These approaches can be achieved through conventional and molecular breeding and through the adoption of advanced agronomy.

This Special Issue is dedicated to the compilation of up-to-date research on vegetable crops’ responses to abiotic stresses and countermeasures for crop protection. We particularly encourage the submission of studies on modern genetic and agronomy methods that alleviate the impact of stress and build resilience in vegetable crop production.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Water scarcity is a critical constraint for agricultural production, particularly in Mediterranean regions, since it is a key stressor directly affecting plant growth, yield, and fruit quality in vegetables. Among others, cherry tomato (Solanum lycopersicum var. cerasiforme) represents a high-value crop with increasing global importance due to its economic, nutritional, and commercial attributes. The objective of this research is to evaluate the seasonal (autumn and spring) effects of reduced irrigation volumes relative to commercial practice on the yield, fruit quality, water-use efficiency (WUE), and physiological responses of cherry tomato plants grown under greenhouse conditions. Plants were irrigated according to growers’ standard practices (100%), as well as 75% and 50% of that water volume, throughout a cultivation cycle of 11 months (August to July). Results indicate strong seasonal variation in quality and physiological parameters (+35.3% single fruit fresh weight and +34.2% flesh firmness, but −68.2% total phenolic compounds content and −38.5% total antioxidant capacity during late autumn assessment). A 50% irrigation level reduction significantly improved water-use efficiency (+82.7%), but reduced single fruit fresh weight (−22.9%) and showed a declining trend in total yield. We conclude that local irrigation practices should be reconsidered in regions highly affected by water scarcity and suggest that the 75% treatment has a practical potential. Full article

Welsh onion (Allium fistulosum L.) is a globally significant culinary vegetable with extensive cultivation and high application value. In China, Welsh onion is vulnerable to drought and strong-light stress in summer production, resulting in growth inhibition and quality decline. This study utilized LED-intelligent spectral-customized lamps to simulate high-light stress and a 10% PEG-6000 Hoagland solution to simulate drought stress. The effects of different stress treatments on the nutritional quality, volatile compounds, and mineral element composition of the edible portions were systematically analyzed. The results demonstrated that drought stress significantly promoted the accumulation of alcoholic compounds in leaf tissues while reducing the content of sulfur-containing compounds. High-light stress markedly increased the levels of hydrocarbon compounds in leaves. Sulfur-containing compounds in leaf tissues were predominantly disulfides, but under combined drought and high-light stress, their content decreased, while the proportion of trisulfides significantly increased. Volatile compounds in pseudostems were primarily composed of sulfur-containing and aldehyde compounds, yet their levels markedly declined under combined stress. Additionally, combined stress led to reductions in pyruvic acid, soluble sugars, and soluble protein content in the edible portions, while the crude fiber content increased, thereby significantly impairing nutritional quality. This study provides a scientific basis for understanding the abiotic stress response mechanisms of Welsh onion and offers valuable insights for cultivation management and quality regulation.
