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 "...

kiwifruit softening and the spread of gray mold on the fruit are the most important factors to be considered in kiwifruit storage life. in this study, the effect of calcium chloride (0, 1, 2, 4 and 8 percent) for 2, 4 and 8 minutes of dipping time were examined to improve the fruit physicochemical characteristics. following fruits being dried (24 hours), they were stored at 0.5oc and 85-90% rh ...

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...

research was carried out in 2007 on 7 native summer-ripening apple cultivars grown in kamal abad karaj research station. the 16 year-old plants were grafted onto seed rootstocks. the cultivars were ghandak-e-kashan, golab-e-isfahan, golab-e-kohanz, mashad, assali, ghermez-e-rezaieh and a new cultivar--koli-e-mahallat (syn. escr). the aim of the study was to identify changes in qualitative and q...

abstract antioxidant capacity and quality of fruits usually changed during storage. in the current study, the changes of antioxidant capacity and postharvest quality of two blood (pigmented) orange cultivars (‘tarocco’ and ‘morro’) and ‘thompson navel’ orange, after 60 days storage at 7ºc and 90 rh% was investigated. during fruit storage weight loss, tss, ta, tss/ta, vitamin c, total phenol, an...

abstract having no exact knowledge of most appropriate harvesting time in kiwifruit grown in different regions of guilan province, as well as the low storage longevity of the fruits are the most important factors causing considerable reduction in both marketability and export affairs. in this study, the influence of fruit quality in term of harvesting time on the postharvest quality and food va...

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...

harvesting time of kiwifruit can influence quality characteristics. the current research was carried out according to a completely randomized design with three replications at faculty of agricultural sciences, university of guilan in 2009. weight loss, flesh firmness, total soluble solid (tss), titritable acidity (ta), ascorbic acid, total phenol content and antioxidant capacity of harvested fr...
