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...

Determination of the optimum harvest window plays a key role in the agro-food chain as the quality of fruit depends on the right harvesting time and appropriate storage conditions during the postharvest period. Usually, indices based on destructive measurements are used for this purpose, like the De Jager Index (PFW-1), FARS index and the most popular Streif Index. In this study, we proposed a ...

Post-harvest losses represent a significant threat to food security and farmer incomes worldwide. It is an inefficiency in the global food production system that is avoidable. In deducing principles of designing and implementing agricultural extension programs to reduce post-harvest losses, valuable lessons can be gleaned from the handful of previous extension projects and programs addressing p...

Abstract The objective of this study was to assess the effects post-bloom (PB) or preharvest (PH) treatments ‘Braeburn’ apple trees with prohexadione-calcium (ProCa; 300 mg L-1), an inhibitor gibberellins biosynthesis, GA4+7 (300 L-1) on fruit quality at harvest and after storage (four months 0±0.5 oC, followed by five days shelf life). PB started 15 full bloom, one application every week six a...

Huge losses in apple production are caused by pathogens that cannot be seen shortly after harvest. After-harvest thermotherapy treatments can considerably improve control of storage diseases on apples and become an alternative to chemical pesticides. In the years 2010-2012 carried out research in this area. Apples of ‘Topaz’ cultivar were harvested at optimal maturity time for long storage and ...

The postharvest quality and longevity of cut flowers is influenced by several factors, with the development stage being one determining aspects. determination harvest point variable must be carried out depending on physiology flower proximity consumer market. In this sense, objective was to determine harvesting ideal stem length for ‘Sol Vermelho’ ornamental sunflower. experimental design adopt...

development of resistant strains of pathogens to many fungicides as well as fungicide residues in food stuff have been resulted in attemps to develop biological agents as alternative methods to control post-harvest diseases. practical use of microorganisms requires formulated products that meet a number of criteria. in this study different carriers for powder formulation of p.guilliermondi were...
