Apple is one of the most important fruits in temperate zones with a long post-harvest life during cold storage. A factorial experiment, in a randomized completely block design was used to investigate the preharvest application of Iron (0, 500 and 1000 mg Fe-EDDHA per tree) and nitrogen (0, 48 and 96 g ammonium nitrate per tree( on some postharvest qualitative characteristics in "Red spur" and "...

in order to alleviate chilling injury in pomegranate (punica granatum) cv. rabab due to cold storage, the fruits were dipped in 0.7, 1.4 and 2 mm of salicylic acid (sa) for 10 min. after 1, 2 and 3 months of storage at 2°c, the fruits were tested for chilling injury (ci) as well as some biochemical parameters. the results revealed that with increase in storage time, ci and ion leakage (il) incr...

in the present study application of x-ray computed tomography as a nondestructive technique for estimation of some qualitative parameters of pomegranate fruit was studied. for this purpose, three local cultivars of pomegranate fruit of fars province, iran that included; rabab malas, rabab torsh and khani kazeroon were used. the x-ray ct images of pomegranate fruits were prepared using ct-scan d...

‘zaferani’ peach, an important native iranian fruit, is a highly perishable fruit of limited shelf life. in the present research, effects of modified atmosphere packaging with three gas combinations (5% co2 + 2% o2, 10% co2 + 2% o2 and air) and two packaging films (polypropylene and low density polyethylene (ldpe)) on physicochemical characteristics and shelf life of 'zaferani' peach ...

in the current research, salicylic acid and putrescine treatments solutions each with 0, 0.5, 1, and 2 mm/l levels were sprayed on the ‘granny smith’ apple trees in three preharvest stages. the treatments were applied based on factorial experiment in the randomized complete block design. weight loss, fruit firmness, total soluble solids (tss), titratable acidity (ta), ph, tss/ta, peel color, an...

Humic acids are the most active components of soil organic matter and have been shown to have an hormone-like activity thus stimulating plant growth. The objective of this work was to verify the quantitative and qualitative yield responses of the table grape cv. Italia after the application of a humic acid at various phenological stages. The humic acid used in this study has been extracted from...

Jujube (Ziziphus jujuba Mill.) fruit is an important medicinal plant in Iran. The harvesting time is a crucial for jujube fruit quality. Several characteristics of jujube fruit when harvested at four development stages; white mature (light green), crisp mature (white-red), fully mature (red) and fully ripe (dehydrated brown) were evaluated. Fruit weight, diameter, volume, pulp to stone ratio, f...

Changes in physicochemical traits, peel colour, and juice attributes of four blood orange cultivars (‘Moro’, ‘Tarocco’, ‘Sanguinello’, ‘Sanguine’) were evaluated during 180 days at 2 5 °C plus 20 for shelf life. ‘Tarocco’ had the lowest weight firmness losses both temperatures storage. Titratable acidity (TA) was higher than °C, with ‘Sanguinello’ showing highest TA, respectively. Juice content...
