Research applications of osmotic dehydration to food processing in technology and in component transfer mechanisms are being carried out in several countries. Osmotic dehydration is a traditional process applied to food dewatering. It leads to attractive products that are ready to eat or can be applied as a pretreatment to the next process such as drying or freezing. The new osmotically dehydra...

In order to investigate the effect of seed pretreatment with growth regulators on biochemical characteristics of red bean genotypes, a factorial experiment was carried out in a randomized complete block design with three replications. In this research, seed pretreatment with growth regulators namely salicylic acid (SA) and naphthalene acetic acid (NAA) were applied at four levels including P0: ...

ABSTRACT: In this study, response surface methodology was used to optimize ultrasound osmotic pretreatment with finished freeze drying of black cherries. Freeze drying is a separation process based on the  sublimation phenomenon. This process has the following advantages as compared to the conventional drying process, maintenance of the structure, moisture removal at low temperature (reduced tr...

BACKGROUND AND AIMS Seed germination is negatively affected by salinity, which is thought to be due to both osmotic and ion-toxicity effects. We hypothesize that salt is absorbed by seeds, allowing them to generate additional osmotic potential, and to germinate in conditions under which they would otherwise not be able to germinate. METHODS Seeds of barley, Hordeum vulgare, were germinated in...

drought resistance is a very important characteristic needed for plant survival especially at germination stage, in arid and semi-arid lands. phosphatase enzymes are widely found in plants. these enzymes are responsible for dephosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted in two bread wheat cultivars (sardari and alvand) under s...

Maize (Zes mays L.) embryos, isolated from the developing seed and incubated in dilute buffer, show reduced triacylglycerol (TAG) synthesis, and accumulation stops after 24 h. Synthesis and accumulation can be maintained at high levels if the incubation medium contains abscisic acid (ABA) and/or a high osmotic concentration. Radiolabeled free fatty acids accumulate at higher levels in embryos t...

An experiment was conducted to see the impact of osmotic stress as it is one of the main cause in various soil and water disorders in agricultural field crops, speciallythe seed germination and seedling growth. The osmotic stress was generated using PEG-6000 and the seed germination, seedling growth were evaluated including the status of pigments i.e. chlorophyll (a, b and total), total caroten...

Stage-specific analyses of starch and 18 sugars, including pentoses, hexoses, disaccharides, trisaccharides, oligosaccharides and sugar alcohols, were made throughout seed development for zygotic embryo and female gametophyte (FG) tissues of loblolly pine (Pinus taeda L.). Tissue was most often analyzed in triplicate from two open-pollinated families grown in different locations and sampled in ...

MUT, Z. and H. AKAY, 2010. Effect of seed size and drought stress on germination and seedling growth of naked oat (Avena sativa L.). Bulg. J. Agric. Sci., 16: 459-467 Effects of seed size and osmotic stress on germination and seedling growth of five naked oat genotypes were investigated in this study. Oat genotypes were Mozart, CROA 60, Detvan, Eva 1 and AC Belmont. Small, medium and large seed...
