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...

pollen storage could facilitate the date palm hand pollination through saving time and space. the main concern is maintaining pollen viability, which is greatly cultivar dependent and is influenced by storage condition. in this study, to address this issue, the effects of cultivar, storage temperature, and time on pollen germination were investigated. a factorial experiment was laid out in a co...

native population of raspberry fruits (rubus spp) were treated with methyl jasmonate (mj) fumigation and were assayed for the antioxidant capacity, total anthocyanins and postharvest quality after 7 days storage at 4?c. the result of experiment revealed that berries treated with methyl jasmonate (mj) showed higher antioxidant capacity and total anthocyanins compared to the controled ones (non...

many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (asf) of such systems. in this paper, the behaviour of integrating the phase change material (pcm) in sdhw systems is modelled and optimized numer...

most of the citrus fruits, especially in north of iran are stored in common storages. this experimen in oder to persevere appearance and internal fruit quality were conducted in the citrus research station at 1392, britex-ti wax, storage wax, polyethlene bag (individual fruit), polyethlene bag (pair fruits) were used alone and with combination with methyl salicylate (mesa) vs. control (without ...

the different factors such as harvest time, product handling, temperature and storage duration can be influenced on the different properties of citrus fruits and has considerable economic consequences. therefore a factorial experiment based on completely randomized design with 3 replications was performed to evaluate the effects of harvest times (start of color change, 50% of color change and f...

in a large scale cyclic storage system ,as the number of rule parameters and/or number of operating period increase, general purpose gradient-based nlp solvers and/or genetic algorithms may loose their merits in finding optimally feasible solution to the problem. in these cases hybrid ga which decomposes the main problem into two manageable sub-problems with an iterative scheme between ga and l...

adverse environmental storage conditions including high temperature and relative humidity could affect seed quality. the objective of this investigation was to quantify relationship between temperatures and seed moisture on seed deterioration and determination viability constants in sorghum. four storage temperatures (5, 15, 25 and 35oc) and three moister content levels (6, 10 and 14%) were use...

Thermal energy storage (TES) system has been introduced as a practical facility for shifting load from peak hours to off-peak hours. Because of different energy consumption during day and night, peak and off peak period is created on load curve. Ice storage technology which is a kind of TES system, is implemented in different points of the world with the purpose of solving load shifting problem...
