Polyphenol oxidase (PPO) plays a key role in the postharvest pericarp browning of litchi fruit, but its underlying mechanism remains unclear. In this study, we cloned the litchi PPO gene (LcPPO, JF926153), and described its expression patterns. The LcPPO cDNA sequence was 2120 bps in length with an open reading frame (ORF) of 1800 bps. The ORF encoded a polypeptide with 599 amino acid residues,...

native population of raspberry fruits (rubus spp) were treated with methyl jasmonate (mj) fumigation and were assayed for the antioxidant capacity, total anthocyanins and postharvest quality after 7 days storage at 4?c. the result of experiment revealed that berries treated with methyl jasmonate (mj) showed higher antioxidant capacity and total anthocyanins compared to the controled ones (non...

ethylene affects the ripening of fruits and is naturally produced in most plant tissues. its production and accumulation during storage can cause serious damage to stored fruits such as black sweet cherries (cv: takdaneh mashhad). it affects shelf-life and can cause a marked increase in respiration rates, increasing ripening and senescence. in some commodities, accelerated aging and the initiat...

application of edible coatings to enhance storage life of fresh fruit has recently been under considerable attention. this experiment was conducted in order to explore the effect of chitosan coating and storage temperature on the postharvest life of pomegranate (punica granatum l.) fruit. therefore, pomegranate fruits ‘rabbab-e-neyriz’ were dipped in 0, 1 and 2% aqueous chitosan solutions, air ...

The antioxidant capacity, total anthocyanins, total phenolics, volatile compounds, and postharvest quality of strawberry fruit were evaluated after treatment with natural antimicrobial compounds and during storage at 7.5 ◦C. Strawberries treated with methyl jasmonate (MJ) in conjunction with ethanol (MJ-ETOH) showed higher antioxidant capacity, total phenolics, and anthocyanins than those treat...

the effect of different storage temperatures on senescence and postharvest performance in cut scapes of three iris species (iris germanica, iris reticulata and iris kashmiriana) was studied with the aim to develop a cost-effective storage protocol so as to bring out the transportation of these cut flowers. the scapes were subjected to two different storage treatments-dry storage and wet storage...

the main postharvest problems of persimmon in iran are severe softening and disease incidence on the fruits during storage. therefore, delay in softening and/or control of diseases result in the storage life extension of persimmon fruit. the strategy of induced disease resistance in plants by biotic and abiotic treatments is an attractive method for controlling diseases. salicylic acid (sa) is ...

strawberry has a short shelf life and since it is consumed as fresh, the use of healthy and natural methods to increase its postharvest life is necessary. in this study, effect of different levels of thymol and menthol essential oils (0 (distillated water, control), 5, 10 and 15 μl) in the packaging with celofan as fumigation on postharvest maintenance quality of strawberries was studied. quali...

Practices in the citrus industry evolve rapidly to minimize postharvest decay losses, mostly a result of green mold or blue mold, caused by Penicillium digitatum or P. italicum, respectively. Current problems include the continued development of fungicide resistance among these pathogens, and compliance with emerging secondary residue standards and other privatized regulation of production and ...

because of the harmful effects of chemicals on human health and environment, the use of these compounds in postharvest technology of horticultural crops is highly restricted. current study was done to evaluate the effect of aloe vera gel on postharvest quality and storage life of fruit cultivar siahe-mashhad. fruit were treated with aloe vera gel of 25 and 33% for 5 min at 22 °c. control fruit ...
