Pomegranate is a subtropical fruit that is widely consumed as fresh fruit and juice, however, its postharvest life is limited mainly due to storage disorders. The aim of this study was to determine the effect of nitric oxide (NO) on antioxidant activity and quality attributes of pomegranate fruit. The fruits were dipped for two minutes into different NO concentrations (0, 30, 100, 300 or 1000 µ...

The aim of this study was to evaluate the effects of foliar application of boron and calcium on postharvest storage characteristics of Asian pear (Pyrus pyrifolia) fruit. This experiment was carried out in the experimental orchard of Asian pear at Tarbiat Modares University, Tehran, Iran. The treatments were two concentrations of boric acid (0% and 0.5%) and three concentrations of calcium chlo...

oxalate soluble pectin (osp) is related to fruit firmness with respect to the chelation of calcium ions with carboxyl groups of adjacent polyuronide chains. this study was carried out to explore the effect of time of fruit harvest, foliar spray with cacl2 during growing season on osp, polygalacturonase activity (pga), fruit firmness and the effects on fruit shelf life, quality and internal ...

pomegranate is native to subtropical regions of iran. losses of horticultural products are a major problem in the postharvest chain. in this experiment, six different wrapping (polyethylene and paper covering), chemical (calcium chloride and wax) and thermal (4 °c and outdoor) treatments were applied on the fruits of pomegranate cv shirin kolbad and some physicochemical properties were measured...

the effect of different concentration of salicylic acid (0, 1 and 2 mmoll-1) and chitosan (0, 0.5 and 1 percent) on postharvest life and quality of selva strawberry fruit during storage at 2.5±0.5°c with 85-95% rh for 7 and 14 days was studied. decay incidence, marketability, total soluble solids, total acidity, vitamin c content and total antioxidant activity were evaluated during storage. chi...

quince fruit has many benefits to human health and is an excellent source of pectin for jellies and jam industry. the objective of the present research was to study fruit physio-chemical attributes of some quince genotypes at harvest and their changes during cold storage. the fruit of 15 genotypes were harvested at optimum maturity and stored for 0, 30, 60, 90 and 120 days in cold storage and s...

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 ...

The effect of pre-harvest sprays of chitosan on post-harvest decay and quality of strawberries stored at 3 and 13°C was investigated. Strawberry plants were sprayed with 2, 4 and 6 g l, chitosan solutions as the fruit were turning red. A second spray was performed after 10 days. Fruit were picked 5 and 10 days after each spray. Harvested fruit from chitosan sprayed plants were challenged with B...

Litchi fruit has a very short shelf life after harvest, so marketers and consumers alike desire longer periods of storage, transportation and distribution. To extend shelf life, anoxia treatments were used for the fruit. Litchi fruit were exposed to pure N2 for 0, 3, 6, 12 or 24 h. They were then kept individually in closed but vented containers for 6 days in the dark at 20 °C and 95–100 % rela...

Cold storage is extensively used to slow the rapid deterioration of peach (Prunus persica L. Batsch) fruit after harvest. However, peach fruit subjected to long periods of cold storage develop chilling injury (CI) symptoms. Post-harvest heat treatment (HT) of peach fruit prior to cold storage is effective in reducing some CI symptoms, maintaining fruit quality, preventing softening and controll...
