treated with different coating and application of methyl salicylate and salicylic acid are used for reduce chilling injury and maintain the quality of citrus fruit during storage. this experiment was carried out citrus research institute of ramsar in 91 years in order to study enzyme activity that involved in reducing chilling injury and maintain the fruit quality based on split plot design wit...

the pomegranate fruits of cvs. malas yazdi and malas ashkezar were immersed in sa (1 and 2 mm from source of acytyl salicylic acid) for five minutes, in ja (0.3 and 0.4 mm from source of n-propyl dihydrojasmonate) for fifteen minutes, in cacl2 (1 and 2%) for five minutes, and in distilled water for five minutes as control. then, the fruits were stored in cold storage at 1.5±0.5ºc and 85±5% rela...

Plants execute an array of mechanisms in response to stress which include upregulation of defense-related proteins and changes in specific metabolites. Polyamines - putrescine (Put), spermidine (Spd), and spermine (Spm) - are metabolites commonly found associated with abiotic stresses such as chilling stress. We have generated two transgenic tomato lines (556HO and 579HO) that express yeast S-a...

Till recently the term photoinhibition (PI) has been related to PS2 part of photosynthetic electron transport chain, in spite of some publications showing that PS1 can also be inhibited at definite conditions. At chilling temperature and low light intensity PS1 is selectively inhibited while PS2 remains practically unchanged. This review describes the nature of PS1 PI; the differences between P...

cold stress is one of the limiting factors in production of greenhouse vegetables. chemicals offer useful approach to reduce low temperature-induced damages. this study was conducted to evaluate the effect of foliar application of methyl jasmonate (meja) at concentrations of 0 (control), 50, 100, 200 µm) on electrolyte leakage (el), relative water content (rwc), soluble carbohydrates, proline, ...

Chilling effects on respiration during the recovery period were studied in two maize (Zea mays L.) cultivars differing in their tolerance to chilling: Penjalinan, a chilling-sensitive cultivar, and Z7, a chilling-tolerant cultivar. Both cultivars were exposed to 5 degrees C for 5 d, after which measurements were taken at 25 degrees C. Chlorophyll fluorescence analysis in dark-adapted leaves sho...

We examined the effectiveness of intermittent warming (IW), hot water (HW), salicylic acid (SA), and calcium chloride (CaCl2) on the postharvest life of pomegranate fruit cv. ‘Shishe-Kab’ and extending fruit shelf life during cold storage (3°C). Fruit were subjected to cycles of 1 d at 17 ± 1°C every 6 d of storage at 3°C under IW conditions. Pre-storage treatments were HW (50°C) for 3 min, SA ...

The use of edible coatings has surged as a response to the ever-increasing demand for ecologically-friendly methods maintaining fruit quality during storage. This study analyses application different polysaccharide-based coatings, carboxymethylcellulose, chitosan, dextrin and starch, plasticizer agent, glycerol, with shown be most effective in postharvest zucchini cold Subsequently, improve the...
