Article Synopsis
  • The study evaluated various colored cherry tomato cultivars ('Jocheong', 'BN Satnolang', 'Gold Chance', 'Black Q', and 'Snacktom') for their firmness, taste, and nutritional metabolites at ripening stage.
  • Findings showed distinct taste variations and metabolite accumulation linked to the tomato colors: 'Black Q' is rich in chlorophylls and anthocyanins, 'Snacktom' in lycopene, 'Gold Chance' in phenolics, and 'Jocheong' in vitamins and amino acids.
  • 'Gold Chance' had the highest antioxidant capacity, highlighting the potential for breeding programs aimed at enhancing nutritional content through diverse cherry tomato selections.

Introduction: Tannin content and postharvest quality characteristics of persimmon fruit are often determined by the destructive analysis that consumes time, does not allow the acquisition of data from the same fruit continuously, and requires expensive high-performance equipment. This research was done to investigate the potential for non-destructive estimation of astringency and quality parameters in persimmon fruit based on visible/near-infrared (VNIR) spectra.

Methods: VNIR spectra readings, the reference tannin content, and quality parameters were measured from fruits of "Cheongdo-Bansi" and "Daebong" persimmon cultivars at harvest and throughout the ripening/deastringency period.

This study addresses the propagation challenges faced by 'Shine Muscat', a newly introduced premium grapevine cultivar in South Korea, where multiple viral infections pose considerable economic loss. The primary objective was to establish a robust in vitro propagation method for producing disease-free grapes and to identify effective plant growth regulators to facilitate large-scale mass cultivation. After experimentation, 2.

Growing microgreens on trays without substrate in a vertical multilayered growing unit offers several advantages over traditional agriculture methods. This study investigated the yield performance and nutritional quality of five selections of radish microgreens grown in sprouting trays, without a substrate using only water, in an indoor multilayer cultivation system using artificial light. Various parameters were measured, including fresh weight, dry matter, chlorophyll, minerals, amino acids, phenolics, flavonoids, anthocyanins, vitamin C, glucosinolates, and antioxidant activity with four different assays.

This work presents the transcriptome analysis of green 'Hayward' () and gold 'Haegeum' () kiwifruit cultivars after treatment with ethylene for three days at 25 °C. Illumina high-throughput sequencing platform was used to sequence total mRNAs and the transcriptome gene set was constructed by de novo assembly. A total of 1287 and 1724 unigenes were differentially expressed during the comparison of ethylene treatment with control in green 'Hayward' and gold 'Haegeum', respectively.

Cold storage is widely used to prolong the storability of peach fruit. However, prolonged storage at low temperatures results in chilling injury (CI) in some susceptible peach cultivars during or after cold storage. Prestorage high CO and 1-methylcyclopropene (1-MCP) treatments are among the methods reported to alleviate CI and maintain the firmness of peach fruit.

Fruit ripening involves changes in physical, physiological, biochemical, and metabolic activities through the actions of enzymes and regulatory genes. In this study, we elucidate primary and secondary metabolites and antioxidant activities of green 'Hayward' and gold 'Haegeum' kiwifruit cultivars during ripening by comparing ethylene-treated fruit to the control. A total of 36 primary metabolites (20 amino acids, 9 fatty acids, 4 organic acids, and 3 sugars) were identified to be altered significantly during the ripening of both cultivars.

Cold storage of peach fruit at low temperatures may induce chilling injury (CI). Pre-storage 1-MCP and high CO treatments were reported among the methods to ameliorate CI and reduce softening of peach fruit. However, molecular data indicating the changes associated with pre-storage 1-MCP and high CO treatments during cold storage of peach fruit are insufficient.

Vertical hydroponics farming has emerged as an alternative solution to feed the continuously growing world population. Additionally, recent studies reported that the exogenous treatments of jasmonic acid influence the phytochemical composition of Brassicaceae. We conducted this study to determine the effect of preharvest methyl jasmonate (MeJA) treatment on the phytochemical composition and antioxidant activities of soil- and hydroponically grown pak choi.

This study was conducted to assess the physicochemical changes and overall nutritional implications of greenhouse-grown "TY Megaton" and "Yureka" tomato cultivars under on-vine and postharvest ripening conditions. In the first group, tomatoes were harvested from a vine at the breaker, pink, and red ripening stages and sampled immediately. The second group was harvested at the breaker stage and allowed to ripen under room conditions to the pink and red stages based on color values, similar to the vine-ripened samples.
