to study the effects of postharvest treatments of spermidine and putrescine on storage quality of ‘hayward’ kiwifruit, the present research was performed. in november 2010, fruits were hand picked from fajr orchardist corporation in sari and transported to postharvest physiology laboratory. fruits were dipped for 4 minutes in either spermidine or putrescine solutions (0.5, 1.0 and 1.5 mm), and ...

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)...

in present research the effects of four levels (0, 0.5, 1, 2 mm) of each of salicylic acid and putrescine treatments on the quality improvement of granny smith apple fruit were studied. factorial experiment in randomized complete block with three replications on 16 trees, eighteen years in researcher station of agriculture university of tehran was designed. for this purpose the trees were spray...

to determine the effects of pre-harvest salicylic acid (sa) treatments on postharvest life and quality of apricot fruits, four different concentrations (one, 1.5, three and 4.5 mm) were applied six days before harvesting of apricot fruits cv. ‘shamlou’. fruits harvested at commercial maturity stage and stored at 2ºc with 90 percent rh on the same day for a period of three weeks. the fruit was e...

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...

The main objective of this work was to assess the effectiveness of salicylic acid (SA), calcium chloride (CaCl2) or sodium bicarbonate (NaHCO3), and packaging on some qualitative properties of apricot fruit during cold storage. The experiments were conducted using a completely randomized design as factorial, with three replicates. Fruits were dipped in SA (0.1 or 0.5 mM), CaCl2 (1 or 2%) or NaH...

the effects of different concentrations of salicylic acid as compared with control and as well with distilled water treatment were assessed on induction of resistance to chilling injury and quality of sweet lemon during its storage. for the purpose, sweet lemon fruits were treated by immersion method for 5 minutes in salicylic acid (200,400 and 600 mg/lit) and then packed in polyethylene bags t...
