introduction: pomegranate (punica granatum l.) belong to punicaceae family is native to iran and grown extensively in arid and semi-arid regions worldwide. pomegranate is also important in human medicine and its components have a wide range of clinical applications. cracking causes a major fruit loss, which is a serious commercial loss to farmers. fruit cracking, seems to be a problem that less...

Plum fruit has a short shelf life with a rapid deterioration in quality after harvest. The primary goal of this study is to investigate and compare the effect of putrescine and salicylic acid on quality properties and antioxidant activity of plum during storage. The plum fruits (cv. 'Santa Rosa') were harvested at the mature ripe stage, and dipped in different concentrations of putrescine (1, 2...

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 "...

Plots of 19 clones of strawberry (Fragaria ×ananassa Duch.) were planted in 1996. Fruit of 16 clones were harvested in 1997 and fruit of 11 of the same clones plus three additional clones in 1998. Individual plots were harvested on three or four dates in 1997 and from three to seven dates in 1998. Fruit firmness was determined with a penetrometer at harvest, and additional samples were processe...

sensitivity of tomato fruit to low temperature and chilling injury limits the storage, handling and marketability of the fruit. as a recommended postharvest treatment, effects of hot water treatment (hwt) on reducing chilling injury and quality traits, variation of tomato fruits during storage life were investigated. tomato fruits were harvested at mature green stage. they were treated by hot w...

Digital image processing is an emerging tool to predict fruit quality; therefore present study was carried out to develop an image processing technique for investigating the storage life of cantaloupe. Potassium permanganate (KMnO4) impregnated materials were used to prolong the postharvest life of cantaloupe fruit and the effects of these treatments were evaluated by 3 image textural features ...

in this study, the effect of foliar spray with calcium chloride (0, 0.75, 1.5 and 3 g l-1) during 2, 4 and 6 weeks before commercial harvesting time of apple fruit cv. ‘gala’ and ‘delbarestival’ which trained in three different systems (v shape, hightech and cordon) was investigated. the results showed that types of training systems and foliar application of calcium can affect on fruits quality...

Objective: To determine the main indices of evolution postharvest maturity theAtaulfo mango from Soconusco, Chiapas, Mexico.Design/methodology/approach: The analyzed variables were color skin L*, a* and b*, starch, total soluble solids (°Brix), pH, instrumental firmness, color/skin firmness correlation.Results: It was found that, as fruit progresses, stage 1 to 5, values L, TSS pH also increase...

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...
