Fruit and Vegetable Production

Fruits and vegetables are generally known to contain important vitamins, fiber, essential minerals, and vital bioactive compounds that possess health benefits such as anti-inflammatory, antimicrobial, antioxidant, and anticancer properties [...].


The Main Findings of This Special Issue
) investigated selected compositional changes of papaya during ripening, with particular emphasis on nutrition and metabolite distributions between the calyx and stem end of the fruit [7].From their findings, total carbohydrates, total protein, nitrogen, and potassium showed maximum accumulation at the stem end, with fructose, glucose, magnesium, and manganese accumulating at the calyx end [7].

Magnetically Treated Water in Phaseolus vulgaris L.: An Alternative Method to Develop Organic Farming in Cuba
"Magnetic biostimulation" or "magnetopriming" involves exposing water used for priming or irrigation to a magnetic field, with this technological approach proven to be effective with several growth-stimulating effects during germination and plant development [8].Boix et al. (2023) investigated the effect of this technology on the potential of common beans in organic farming, with their work reporting the ability of magnetically treated water to increase germination, stem length, vigor, leaf area, seed weight, and chlorophyll and carbohydrate content [9].

Irrigation Effect on the Yield, Skin Blemishes, Phellem Formation, and Total Phenolics of Red Potatoes
Jiang et al. ( 2022) investigated the benefits of irrigation on Dark Red Norland potatoes known to be drought sensitive.The use of irrigation improved yields by 20.6% and reduced surface cracking by 48.5% [11].Microscopy imaging analysis demonstrated that tubers from the rainfed trials formed higher numbers of suberized cell layers than those of the irrigated potatoes.In addition, surface cracking and silver patch skins had more suberized cell layers than the normal skins.The irrigated potatoes also had a significantly higher concentration of total polyphenols [11].

Changes in Soil Characteristics, Microbial Metabolic Pathways, TCA Cycle Metabolites, and Crop Productivity following the Frequent Application of Municipal Solid Waste Compost
The use of municipal solid waste compost is well established, but Abbey et al. (2022) investigated the effect of long-term changes in soil microbial composition and subsequent translation on plant metabolic pathways.Both annual and biennial applications of municipal compost increased yields, with annual application being the most effective technique [12].Furthermore, the same effect was found with increased microbial function and tricarboxylic metabolites, thus suggesting the potential application of municipal compost as a novel long-term green solution for improving soil health [12].2022) studied the accumulation of biogenic amines in two varieties of grape berries during ripening.Although a difference in biogenic amine concentration between the varieties was observed, there was a consistent increase in concentration throughout the ripening process [13].The concentration of most of the biogenic amines analyzed increased linearly from the beginning of berry touch to when the berries ripened during the harvesting stage.The most common biogenic amine in the grape varieties was putrescine, followed by histamine, agmatine, and tyramine.

The Field Application of a Vis/NIR Hyperspectral Imaging System for the Non-Destructive Evaluation of the Physicochemical Properties of 'Madoka' Peaches
One major challenge in assessing the physiological and biochemical characteristics of fruits and vegetables is the destructive approaches available for quality assessment.To help solve this problem, Jang et al. (2022) evaluated a vis/NIR hyperspectral imaging system as a non-destructive quality assessment method in peaches [14].The coefficient of determination was higher than 0.8 for chromaticity and soluble solids content, although it was slightly lower (0.6 to 0.7) for firmness and titratable acidity.Their study demonstrates the potential of hyperspectral imaging as a method for the non-destructive estimation of specific quality characteristics, and as such, it would be interesting to investigate its use for other parameters.2022) contrasted differences between honeydew melons and cantaloupes grown using Hygromix ® growing media covered in a layer of vermiculite.The accumulated concentrations of vitamin C, β-carotene, zinc, phosphorous, potassium, magnesium, and calcium were all higher in the cantaloupes studied [15].In general, total soluble solids, color intensity, pH, and flavonoids all increased during storage while vitamin C, flavonoids, and phenolics all decreased [15].2022) harvested sweet pepper fruits prior to physiological maturity in order to investigate the seed changes that occur during post-harvest resting (i.e., the time period between harvest and seed collection).The key findings of the study were that potassium, calcium, and magnesium decreased during fruit maturation while seed albumin, globulin, prolamin, and glutelin all increased [16].

The Effect of Pyroligneous Acid on the Productivity and Nutritional Quality of Greenhouse Tomato
Pyroligneous acid is a liquid obtained from the condensation of smoke from biodiesel or biochar formation and has been shown to be a potent biostimulant.Ofoe et al. (2022) applied concentrations between 0 and 2% as a root soak to tomato plants, which increased the number and mass of the tomato fruits [17].The concentrations of several bioactive compounds such as total phenolics, flavonoids, and ascorbate were also improved by pyroligneous acid, as well as total dissolved solids [17].It was shown through this study that pyroligneous acid could play a role in greenhouse tomato production.

Plant Growth-Promoting Rhizobacteria Improve the Growth and Fruit Quality of Cucumber under Greenhouse Conditions
Zapata-Sifuentes et al. (2022) studied the effect of three rhizobacteria species on cucumber plant growth in the hopes of reducing dependency on chemical fertilizer inputs.All three investigated species demonstrated improved cucumber growth parameters such as plant height, fruit length, and yield [18].The researchers also observed significant accumulated levels of phenolics, flavonoids, and vitamin C and improved antioxidant capacity [18].From the results of their study, it was found that rhizobacteria have the potential to improve both the quantity and quality of cucumbers.

Ascorbic Acid's Preconditioning Effect on Broccoli Seedling Growth and Photosynthesis under Drought Stress
MacDonald et al. (2022) explored the use of ascorbic acid as a seed priming agent in broccoli following previous success in other species.Broccoli was not grown to harvest in this experiment, but there were increases in critical parameters such as plant growth, photosynthesis, water use efficiency, leaf area, and membrane protection [19].Perhaps more interesting is that these same critical parameters also increased during drought stress, pointing to ascorbic acid having a role in increased plant growth and drought stress mitigation.
