“…The results of the analyzed bioactive compounds in wild garlic leaves under different storage conditions (Table 2) demonstrate that wild garlic leaves have a higher ascorbic acid content compared to lettuce [26] and similar levels to spinach [27]. This suggests that wild garlic can be a potential source of ascorbic acid in the diet [28]. However, Voća et al noted that the ascorbic acid content depends on the harvesting period and is lower when wild garlic starts flowering [11].…”

Medicinal and aromatic plants, such as wild garlic (Allium ursinum), are valuable sources of bioactive compounds in traditional and modern medicine. However, the challenges in cultivating wild garlic and its seasonality limit its availability primarily to early spring. To maintain the quality of wild garlic, effective postharvest practices are essential, considering the delicate nature of its leaves and their susceptibility to rapid decay. This study focuses on implementing eco-friendly postharvest practices to address the seasonality and perishability of wild garlic. Optimizing storage conditions and drying processes is essential for extending its shelf life and preserving bioactive components. Two postharvest approaches were evaluated, with vacuum packaging at 4 °C demonstrating the most effective preservation of sensory attributes and bioactive composition over a 9-day period. Additionally, different drying methods, including convective and vacuum drying at various temperatures, were investigated. When the best drying temperature was selected, the results revealed that convective drying is more efficient at preserving phenolic compounds in wild garlic leaves at 60 °C. Conversely, vacuum drying shows superior preservation of alliinase activity and total thiosulfinate content at 70 °C. Furthermore, this study explores the utilization of unused wild garlic, which is typically discarded as waste during storage. By employing suitable drying methods, this material can be preserved and provide a valuable source of phenolic compounds (7.17–10.12 g GAE/100 g) and thiosulfinate (9.35–12.72 mg AC/110 g) compounds for various extraction processes. Accordingly, this research presents significant implications for the integration of wild garlic into diverse industries, particularly in the fields of food and pharmaceutical sectors. The findings offer opportunities for sustainable utilization, economic benefits, and a more environmentally friendly and economically viable approach to wild garlic production and processing.

“…Spinach is known as a source of many vitamins and minerals. Spinach, which is also very valuable in terms of its free radical scavenging vitamin A, B, E, K and C content, is an important type of vegetable for people sanitary (Wang et al, 2023). Spinach, which is a cool climate vegetable, is swelled in open elds during spring, winter, and autumn in subtropical area, while it is swelled in spring or autumn in regions where the continental clime wins out.…”

Flooding stress with the impact of global climate change has recently become a major stress factor that limits the productivity and quality of many agricultural areas. Recently, researchers have been working to abate the negative impacts of flooding stress. Studies have shown that nitric oxide (NO) applications abate the negative impacts of different types of flooding stress. For this purpose, the current study tried to determine the effects of different NO doses on spinach under flooding stress situations. In te present study, there were six application subjects: full irrigation - control (FI), flooding stress (FS), FS + application of 50, 100, 150 and 200 µM NO. NO was applied to spinach as a foliar spray twice, one week apart, under flooding stress situations, which was applied for ten days close to the harvest period. Flood stress agronomic parameters, leaf number (LN), leaf area (LA), shoot fresh weight (SFW), root fresh weight (RFW), shoot dry weight (SDW) and root dry weight (RDW) caused decrease of 40, 24, 57, 46, 49 and 20%, respectively. In addition, actual photosynthetic efficiency (QPSII) caused significant decrease. On the contrary, flooding stress revealed significant increase in hydrogen peroxide (H2O2), malondialdehyde (MDA) and proline (PRO) contents. It has been observed that applied NO doses not only promote plant growth but also support photosynthesis by increasing pigment content. In addition, it promoted antioxidant enzyme activity by reducing H2O2 and MDA content. As a result, it was revealed that 50 µM NO application increased tolerance to spinach under flooding stress situations.

“…The capabilities of melatonin in the production of horticulture crops is a promising area of study. Melatonin has been found to influence the expression of genes involved in stress response, hormone signaling, and antioxidant defense, improving stress tolerance and growth in horticultural crops [9][10][11]13]. It can also interact with other phytohormones, viz cytokinins, auxins, and abscisic acid, to promote root growth, postpone senescence, and improve resistance [12,14,15].…”

Melatonin, a hormone known for its role in regulating sleep–wake cycles in mammals, has been found to have diverse functions in horticultural plants. In recent years, research has revealed the involvement of melatonin in variousphysiological processes in plants, likeregulation of growth and development, stress tolerance, and antioxidant defense. Melatonin can augment seed germination, roots, shoot growth, and biomass accumulation in horticultural crops. It also performs a vital role in regulating vegetative and reproductive growth stages, floral transition, and leaf senescence. Melatonin improves stress tolerance in cropsby regulating root architecture, nutrient uptake, and ion transport. Additionally, melatonin works like a broad-spectrum antioxidant by scavenging reactive oxygen species and enhancing antioxidant activity. The mechanism of action of melatonin in horticultural plants involves gene expressions, hormone signaling pathways, and antioxidant defense pathways. Melatonin also interacts with other plant growth regulators (PGRs), comprising auxins, cytokinins, and abscisic acid to coordinate various physiological processes in plants. Melatonin has evolvedas a versatile chemical entitywith diverse functions in horticultural plants, and its potential applications in crop production and stress management are increasingly being explored. This reviewaimsto provide a comprehensive insight into the present state of knowledge about melatonin and its role in horticulturally important plants and identify avenues for further research and practical applications. Further study must be conductedto fully elucidatethe mechanisms of melatonin action in crops and to outline effective strategies for its practical use in horticultural practices.
