Harvested fruits and vegetables are threatened by pathogens which can cause losses for up to 55 % depending on the fruit and country. A potentially sustainable control method is the biological control of these postharvest diseases using biocontrol agents (BCA). Nevertheless, the lack of reliability in practical conditions compared with synthetic chemical pesticides is a major hinderance. Strategies

Many studies have focused on the plant hormone ethylene because of its key role in controlling, among others, climacteric fruit ripening and fruit senescence. These processes can be controlled by applying 1-MCP, which tightly binds to the ethylene receptors thereby blocking the ethylene signaling pathway. 1-MCP is known to inhibit the action of ethylene and to delay the climacteric ripening of tomato

β-Aminobutyric acid (BABA) is a nonprotein amino acid that induces plant defense responses to numerous biotic and abiotic stresses. However, whether BABA treatment affects the wound healing process of potato tubers has yet to be reported. In this study, we examined the effects of BABA treatment on the weight loss and disease index of Solanum tuberosum L. cv. Atlantic potato tubers inoculated with Fusarium

This study explores the possibility of predicting the soluble solids content (SSC), firmness and the presence of internal browning disorders in ‘Rocha’ pear (Pyrus communis L.) using a single VIS-NIR spectroscopic measurement in semi-transmittance mode. The spectroscopic measurement setup was developed to mimic real world conditions and takes into account geometry and technical requirements of a commercial

Suberin poly phenolic is an important component of healing tissue. We aimed to develop a new method to accelerate wound healing of harvested muskmelons. In this study, the plants and fruits of muskmelons were sprayed with 0.1 % chitosan four times during fruit development to evaluate the effect of chitosan treatment on wound healing of harvested muskmelons. The results showed that preharvest chitosan

Postharvest fumigation of fruits and vegetables is an important tool for managing pests and diseases that can cause devastating loss if not properly controlled. Sulfur dioxide (SO2) may have promise as replacement for methyl bromide, which is expected to be phased out. However, SO2 is known to cause injury to small fruit such as table grapes (Vitis vinifera L.). We extend previous research on SO2 fumigation

To understand the relationship of optical properties with soluble solids content (SSC) and moisture content of strawberry during ripening, a single integrating sphere system was built to estimate the absorption coefficient (μa) and reduced scattering coefficient (μs') of strawberry in white, color turning and red ripening stages over the wavelength range of 550−850 nm and 950−1650 nm. The relationship

Curved surface of fruit has a great influence on the measurement of absorption (μa) and reduced scattering coefficients (μ’s) by using the spatial frequency domain imaging (SFDI) technique. In this study, a developed SFDI system was used to conduct phase-measuring profilometry (PMP) to obtain the surface height of tested object. Monte Carlo (MC) simulation was conducted on planar and spherical geometric

L-lysine, an important basic amino acid, its catabolic pathway is activated upon microbial pathogen attack in plants and has a central role in plant immunity. The control effects of exogenous L-lysine treatment on Alternaria rot in postharvest ‘Zaosu’ pear fruit and possible mechanisms involved were studied. The results showed that L-lysine treatment inhibited Alternaria rot development and the effect

This research was conducted to investigate the mechanism of 1-methylcyclopropene (1-MCP) treatment on ascorbic acid (AsA) content in kiwifruit after harvest. Our findings indicated that 1-MCP treatment postponed the course of fruit senescence and maintained higher contents of AsA and total ascorbic acid (T-AsA) during storage in postharvest kiwifruit. Gene expression analysis revealed that the transcription

The effect of melatonin on chilling injury of banana fruit was investigated. Results showed that melatonin treatment delayed chilling injury and alleviated peel browning. Melatonin treatment increased the contents of phospholipids and unsaturated fatty acid, induced the reactive oxygen species (ROS) scavenging enzyme activities, and reduced the contents of H2O2, O2– of banana fruit. It also induced

The bruising phenomenon of apple fruit under impact loading is still a very important problem to be solved in order to design optimal harvest and processing systems and for ensuring the quality of the fruit during long-term periods of storage. This study focused on deformation simulation of apples (cv.’ Pink Lady’) under dynamic impact loading during drop tests in order to describe time-dependent bruising

Blueberry is one of the major health foods, which is susceptible to microbial contamination during the postharvest storage period. More seriously, the gray mold caused by Botrytis cinerea (B. cinerea) is a major postharvest disease of blueberries. Atmospheric cold plasma (ACP) holds a great potential as an efficient, economical and ecofriendly method for food sterilization. Herein, this study investigated

Goji berry is a perishable fruit after harvest. To explore the biochemical and molecular mechanisms by which salicylic acid (SA) suppresses rot in goji berry, the fruit was treated with SA and stored for 30 d. Compared with the control, the SA-treated fruit showed smaller lesion areas during storage at 20 °C. During storage at 0 °C, the O2∙¯ production and H2O2 levels were lower in SA-treated fruit

Fruit ripening is a complicated biological process, in which the levels of reactive oxygen species (ROS) fluctuate. However, the molecular mechanisms of ROS in the regulation of fruit ripening are still unclear. Here we utilized an iodoacetyl tandem mass tag (iodoTMT)-based redox proteomic approach to detect the redox dynamics of proteins during tomato fruit ripening. A total of 70 cysteine (Cys)-containing

Kiwifruit may be stored for prolonged periods at low temperatures during which time the fruit continue to ripen slowly and dehydration occurs. Abscisic acid (ABA) plays important roles in both fruit ripening and environmental stress response, including dehydration. To investigate the inter-relationships among postharvest dehydration, ethylene production, ABA and fruit ripening, two independent experiments

Aroma is a vital characteristic that determines the quality and commercial value of fruit. Fatty acids (FAs) are key precursors for fruit aroma volatiles. In Arabidopsis thaliana, TT2/MYB123 inhibited the seed embryo FA biosynthesis. We analyzed the function and regulation of the MYB123 homolog (Fragaria × ananassa [Fa] MYB11) for FA metabolism, especially lipoxygenase (LOX) pathway. FaLOX5 was correlated

NAC (NAM, ATF1/2 and CUC2) is a transcription factor that can regulate many physiological and biochemical reactions in plants. Two NAC genes, SNAC4 (NM_001279348.2) and SNAC9 (NM_001365397.1), with similar secondary structures have been isolated from tomato (Solanum lycopersicum L.). The pattern of SNAC4/9 co-regulation of tomato ripening with abscisic acid (ABA) and ethylene through yeast two-hybrid

To avoid losses from sprouting during potato storage, the anti-sprouting agent chlorpropham [CIPC] has been widely used over the past few decades. However, the European Union recently decided not to authorize the renewal of CIPC, prompting the value chain to find alternative treatments. We assessed for three years the potential of pre- and post-harvest anti-sprouting treatments to replace CIPC using

The potent role of endogenous melatonin (MEL) in affecting chilling injury (CI) and related chilling tolerance regulatory mechanisms in harvested litchi fruit during refrigeration at 4 °C were investigated in this study. In the first experiment, exogenous MEL exposure exerted an inhibitory impact on the development of CI severity in refrigerated litchi fruit, as indicated by the lower CI index and

Refrigeration is the most common way to store ‘Nanguo’ pears. However, their pericarps are prone to browning during the shelf life after refrigeration. In this study, we examined the effects of polyamines (PAs) on pericarp browning and analyzed their impact on mitochondrial morphology and function. Exogenous PAs substantially alleviated the onset and development of pericarp browning in pear fruit treated

Bell pepper (Capsicum annuum L.), with its wide array of colors and flavors, plays an important role in many different cuisines around the world. Yet once harvested, it is a highly perishable fruit and needs appropriate post-harvest handling. Recently, post-harvest internal rotting (IFR) by Fusarium lactis species complex isolates (FLASC), became an additional challenge to maintain shelf-life and quality

Grapes are high nutritional and economic fruit but extremely vulnerable to fungus infections during postharvest storage. Our previous study found that the fungi, Talaromyces rugulosus O1 secretes ochratoxin A (OTA), which inflicts consumer health and economic value. This study found that T. rugulosus O1 has strong pathogenicity and spore germination to produce germ tubes to help it infect grapes. To

Pomegranate fruit is prone to moisture loss irrespective of its thick rind and tough leathery outer skin, resulting in compromised visual appearance and financial loss. The aim of this study was to identify and characterise structural changes in lenticels, micro-cracks, wax patterns and peel tissue fractions to aid the understanding of water loss trends in pomegranate fruit during storage. Fruit were

Strawberries (Fragaria × ananassa Duch. cv. Akihime) were treated with different concentrations of exogenous strigolactone (SL) (0, 0.5, 1, 2, and 4 μmol L−1). Changes in the antioxidant system, nitric oxide (NO) synthesis, hydrogen sulfide (H2S) synthesis, and phenylpropanoid metabolism of postharvest strawberries were studied. Among the treatments, 1 μmol L−1 SL significantly inhibited peroxidase

Heat stress plays an important role in a postharvest biocontrol system. A basic understanding of heat stress response is crucial to the use of antagonistic yeasts as postharvest biocontrol agents. In the present study, heat stress (42 °C, 20 min) decreased the biocontrol efficacy of the yeast antagonist, Debaryomyces hansenii, against gray mold, caused by Botrytis cinerea, on kiwifruit. RNA-seq was

Physiological storage disorders continue to cause sizable economic losses in a range of commercially important pomefruit cultivars. Given similar storage regimes, the incidence and severity of browning disorders in the apple cultivar ‘Braeburn’ can vary in different years in a way that can be explained by the interaction of preharvest seasonal and orchard factors. Over a three-year period (2016–2019)

Hydrogen-rich water (HRW), normally produced by water electrolysis, is a major method for hydrogen gas (H2) delivery, and had beneficial outcomes in postharvest preservation of cut roses. Since the preparation of HRW is complicated and required a H2 generator, the development of a convenient hydrogen supply in horticulture is required.

Inner tray is an important factor contributing to cooling heterogeneity. However, the study about the design optimization of inner tray is rather limited. The present study focused

The quality traits of table grape most appreciated by the consumers are berry size, bunch architecture, and freshness appearance (especially after post-harvest cold storage). Loss of bunch freshness reduces the value and selling potential for the market. Application of plant growth regulators (PGRs) may improve quality, particularly in seedless cultivars that naturally set compact bunches with small

Citrus fruit are highly susceptible to infection by several fungal pathogens during postharvest storage. Therefore, harvested citrus fruit receive a series of treatments in the packhouse such as initial drenching, washing and disinfection, immersion in heated solutions of chemical fungicides and waxing that also include fungicides to reduce the inoculum load, eradicate existing infections and protect

The present study showed that hydrogen sulfide (H2S) plays a critical role in reducing the colour change of Lanzhou lily during storage, which has not been previously reported. We detected the colour change, especially the violet-red colour, of lily-bulb scales that were treated with different concentrations of NaHS (a H2S donor) by the L*, a * and b* and the browning degree of the scale surface. The

Mangosteen (Garcinia mangostana L.) is a tropical fruit with numerous beneficial properties such as anti-cancer, anti-oxidant, and anti-microbial activity. This is due to the presence of potent secondary metabolites such as phenolics, and xanthones, which are differentially accumulated during ripening. However, the molecular regulation that governs mangosteen ripening and hence metabolic changes has

The ‘Granny Smith’ is a commercial apple cultivar in Western Australia and popular in the apple world as well, for its unique green colour and flavour.

The best

A model of elastic impact (EI) and a model that considers energy dissipation (CED model) were developed to describe the deformation behavior during litchi impact. In the CED model, dissipation energy is due to damping effect and the change of elastic modulus after impact. Drop tests of fruit onto a fixed plate were conducted with a pendulum device for three litchi cultivars (‘Nuomci’, ‘Guiwei’, and

The function of inositol 1,4,5-trisphosphate (IP3) in nitric oxide (NO)-induced chilling tolerance in postharvest kiwifruit was revealed. The fruit were treated using sodium nitroprusside (SNP; exogenous NO donor) and neomycin (IP3 inhibitor). Data demonstrated that compared with the control, chilling injury (CI) index and firmness decreased and increased upon SNP treatment in kiwifruit. SNP treatment

The main objective of this study was to evaluate the physiological and quality changes of fresh-cut red chard (Beta vulgaris) and rocket (Diplotaxis tenuifolia) leaves illuminated during storage with monochromatic light emitting diode (LED) lamps, featuring different spectral component (red, green, yellow, white, blue and far-red) and same light intensity (35 μmol m−2 s-1). As control, storage in darkness

MADS box transcription factors (TFs) play important roles in different biological processes, for example, fruit ripening. However, the roles of MADS box TFs in papaya fruit ripening remain a little know. In this study, a novel MADS-box gene was found, named as CpMADS4, and its expression level was decreased during fruit ripening. Protein-protein interaction assays proved that CpMADS4 interacted with

The effects of a sodium alginate (SA) coating combined withl-cysteine (L-cys) and citric acid (CA) on browning and microbial growth in fresh-cut lotus root slices during storage at 4 °C were investigated. The SA + L-cys + CA treatment was more efficient than separate SA andl-cys + CA treatments in the maintenance of visual appearance and flavour quality. The SA + L-cys + CA coating improved the ability

Our previous report indicated that tomato (Solanum lycopersicum) fruit of two contrasting varieties in the chilling tolerance showed the opposite expression pattern of a mitochondrial small heat shock protein (M-sHSP23.8) gene after chilling stress. Thus, the fruit of the relatively tolerant variety Micro-Tom strongly accumulated M-sHSP23.8 transcripts while the susceptible var. Minitomato fruit did

Fruit worldwide are prone to insect damage, particularly from the Tephritidae fruit flies. The Queensland fruit fly (“QFF”, Bactrocera tryoni) is one of the worst economic pests in the Pacific. Females oviposit in a wide variety of fruit and larvae develop inside the flesh with minimal external visual damage early upon infestation. The export of infested fruit into pest-free zones is one of the main

Mangostenn (Garcina mangostana) is a climacteric fruit and thus, there is need for intervention on its postharvest preservation to delay ripening, reduce spoilage and microbial infestation, and possibly enhance its availability all year round. This study was aimed at determining the best application ratio of the combination of peppermint oil (PO) and lime oil (LO) essential oils (EOs) in slowing down
