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...

The objective of this study was to evaluate the quality strawberries distributed in global markets. We obtained from Egypt, Mexico, Republic Korea, Spain, and United States America (US) being sold Singapore, compared them with Japanese (cv. Benihoppe) using instrumental analysis sensory evaluation. Sensory evaluation conducted by Singaporean assessors. results showed that Egypt were relatively ...

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...

barhee is considered as one of the most popular date cultivars worldwide. its fruits, because of low tannin content and low astringency can be, and are consumed at khalal stage. due to its high water content and respiration rate, khalal date fruit is very perishable and of low storage life. limited supply, and difficulties involved in marketing of this product, makes one think of new packaging ...

relative resistance of 43 iranian as well as introduced apple cultivars to blue mold (penicillium expansum) was studied within years 2010-2011. the fruit physicochemical traits were also evaluated as measures of potential resistance to decay. local p. expansum strains were isolated from decayed apple fruits and the most aggressive isolate (5,000 spores ml-1) used as inoculum. fruits were wound-...

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 ...

background: an essential oil is a liquid that is generally distilled from the leaves, stems, flowers or other elements of a plant. objective: cumin (cuminum cyminum l.) essential oil (ceo) was analyzed to determine oil component. antifungal effect of ceo was determined by in vitro technique. in second stage, effect of different concentrations of ceo by pdm on postharvest life of strawberry (fra...

the use of natural compounds to control plant pathogens lead to reduction in using fungicides. chitosan with duble effects, control pathogenic microorganisms and activate inducing defence responses, has been shown to be a reliable nontoxic material in the plant-pathogen interaction. the aim of this research was to consider the effects of chitosan and calcium chloride on decay and quality attrib...

Th e aim of this study was to determine the chemical composition and antioxidants capacity of three plum cultivars, namely ‘Top’, ‘Elena’ and ‘Bistrica’. Fruits were harvested and following parameters were determined: dry matter, total acids (TA), total soluble solids (TSS), pH, vitamin C, total phenols, nonfl avonoids and antioxidant capacity. Diff erences between cultivars for most of the che...
