Hardy kiwifruits (Actinidia arguta) were treated with 20 μl/l 1-methylcyclopropene (1-MCP) for 16 h at 10 °C and subsequently stored 1 ± 0.5 °C. Anticancer properties of the fruit extracts tested against five different human cancer cells. The hardy kiwifruits, without 1-MCP treatment, showed increases in both respiration ethylene production rates during storage. treatment remarkably inhibited ripening by reducing production. Fruits could be up to 5 weeks maintaining higher firmness, ascorbic...

This study was carried out to better understand the mechanism responsible for increasing anthocyanins in blueberries after UV–B radiation at 6.0 kJ m–2 20 min. induced upregulation of genes involved anthocyanin biosynthesis blueberry fruit compared a nontreated control. Phenylalanine ammonia lyase, chalcone synthase, and flavanone 3′-hydroxylase, which are enzymes that function upstream biosynthesis, were significantly expressed by UV–B. Expression levels VcBBX, VcMYB21, VcR2R3MYB...

Harvested strawberry (Fragaria × ananassa) fruit has a short shelf life due to rapid postharvest metabolism, quick softening, mechanical damage, and fungal decay. To improve the storability of fruit, we subjected harvested short-term exposure 30% carbon dioxide (CO2) used transcriptomic metabolomic analyses identify cellular responses induced by this treatment. Fruit was stored at 10 °C for d after 3-h CO2 (treatment) or ambient air (control) 25 °C, respectively. The treatment reduced decay...

Radish (Raphanus sativus L.), a root vegetable, is rich in glucosinolates (GLs), which are beneficial secondary metabolites for human health. To investigate the genetic variations GL content radish roots and relationship with other phenotypes, we analyzed 71 accessions from 23 different countries GLs using HPLC. The most abundant was glucoraphasatin, four-carbon aliphatic side chain. of glucoraphasatin represented at least 84.5% total content. Indolyl only 3.1% its maximum. principal...

Ultraviolet (UV)-A, -B, and -C were radiated to full-ripe blueberries (cv. 'Duke'), their effects on fruit qualities phytonutrients during subsequent cold storage investigated. The exposed each UV light at 6 kJ/m(2) then stored 0 °C for 28 days. Weight loss decay of the fruits after treatment significantly decreased storage. total phenolics antioxidant activities UV-B treatments always higher than those control UV-A treatment. Individual anthocyanins markedly increased 3 h treatments....

Pepper (Capsicum annuum L.) fruit is affected by chilling temperatures below 7–10 °C; thus, there are limitations to maintaining postharvest freshness during its cold storage and distribution. Here, the six endogenous hormones, abscisic acid, gibberellic indole-3-acetic acid (IAA), jasmonic jasmonoyl-isoleucine, salicylic were quantitatively analyzed, genes amino acids associated with them investigated under hypothesis that hormones primarily involved in injury (CI) of pepper fruit. two...

Postharvest storability is an important trait for breeding strawberry ( Fragaria × ananassa Duch.). We evaluated the postharvest fruit quality of five cultivars (‘Durihyang’, ‘Kingsberry’, ‘Maehyang’, ‘Seolhyang’, and ‘Sunnyberry’) identified differences in their ripening during transition from big-green to fully-red stage between two with highest (‘Sunnyberry’) lowest (‘Kingsberry’) storability, using comparative transcriptome -metabolome analysis. The differentially expressed genes...

Postharvest storage plays a key role in determining the marketability of kiwifruits. 'Haegeum' (Actinidia chinensis var. cv. 'Haegeum'), golden-fleshed kiwifruit, although gained popularity, knowledge its postharvest qualities is limited. Here, we performed comparative analysis physicochemical characteristics and green-fleshed 'Hayward' (A. deliciosa 'Hayward') kiwifruit. The fruit were stored for 1, 2, or 3 months at 0 °C after harvest subsequently transferred to room 25 week induce...

Mineral malnutrition affects billions of people all over the world and biofortification staple crops provides a potential way to alleviate dietary mineral deficiencies. For example, nutritional quality is an important breeding target for fresh waxy maize (Zea mays L.), which widely consumed in Asian countries. Successful improvement composition will require comprehensive profiling varieties understanding capacity grains accumulate minerals. Here, using inductively coupled plasma absorption...

Abstract Sulforaphene (SFE), a major isothiocyanate in radish seeds, is close chemical relative of sulforaphane (SFA) isolated from broccoli seeds and florets. The anti-proliferative mechanisms SFA against cancer cells have been well investigated, but little known about the potential effects SFE. In this study, we showed that SFE purified inhibited growth six cell lines (A549, CHO, HeLa, Hepa1c1c7, HT-29, LnCaP), with half maximal inhibitory concentration values ranging 1.37 to 3.31 μg/mL....
