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 "...

effects of pre-storage application of salicylic acid (sa) and storage periods were investigated on phenylalanine ammonia lyase (pal) activity, chilling index (ci) and quality of pomegranate (punica granatum) cv. malase saveh. the results showed that with increase in sa concentration up to 2mm, ci and ion leakage (il) were reduced while pal activity being increased. the lower il and ci vc the hi...

the harvest date more influenced on postharvest quality during storage. in present study, fruits were harvested at four date base on total soluble solids content (5.5, 6.5, 7.5, and 8.5%) and then stored at 0.5 ºc and 80-90% rh, for 18 weeks. the samples were taken in 6th, 12th and 18th interval weeks and evaluated some parameters including weightless, losses, firmness, tss, ta, tss/ta, ascorbi...

In this study, the effectiveness of chitosan coating treatment to control weight loss and maintaining fruit quality of apricot was investigated. Fruits were coated with 0.25%, 0.5% and 0.75% chitosan as well as distilled water (control). Following treatments, fruits were stored at 0?C and 80 ? 2% relative humidity for 25 days. The weight loss, total soluble solids (TSS), titratable acidity (TA)...

‘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 this study, the effectiveness of chitosan coating treatment to control weight loss and maintaining fruit quality of apricot was investigated. fruits were coated with 0.25%, 0.5% and 0.75% chitosan as well as distilled water (control). following treatments, fruits were stored at 0?c and 80 ? 2% relative humidity for 25 days. the weight loss, total soluble solids (tss), titratable acidity (ta)...

the type of training system and application of calcium spray have considerable effects on storability of fruits. in this study, the effects of calcium chloride spray (0, 0.75, 1.5 and 3 g.l-1) in three times during 2, 4 and 6 weeks before harvest time on apple (malus domestica) fruits cvs. ‘gala’ and ‘delbarestival’, which trained in three different training systems (v shape, hightech and cordo...

to prolong the storage life and quality of 'zafarany' peach, fruits were treated with uv-c irradiation with dosage of 1.435×10-4 wcm-2 with three time durations (0, 5 and 15 min) and as well immersion of fruits in 0 and 3% cacl2 solution. the experiment was carried out in a completely randomized design (factorial experiment) of four replications. fruits were harvested in commercial ma...

in this study the effects of plant growth regulators including; ga3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (perlette and yaghuti). at the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and l/d ratio, flesh firmness, fresh weight, ta, ph, tss and fruit color were ...

the effect of the organic, integrated and conventional methods of kiwifruit cv. 'hayward' production on the fruit quality at its harvest time was investigated. such traits as fruit size, firmness, total soluble solids (tss), titratable acidity (ta), total chlorophyll, total carotenoids, vitamin c, total phenol, flavonoid compounds (catechin, quercetin 3-glucoside and chlorogenic acid)...
