In this study some selected chemical properties such as total soluble solids, pH, total acidity, formalin index,  reduced sugar content and ascorbic acid of major sour cherry cultivated grown in different provinces of Iran corresponding were investigated.  Minerals K+, Na+, Ca2+, Mg2+, Cu2+, Fe2+ and Zn2+ were determined by graphite furnace atomic absorption spectrophotometer. The result showed...

Sugar transporters are central machineries to mediate cross-membrane transport of sugars into the cells, and sugar availability may serve as a signal to regulate the sugar transporters. However, the mechanisms of sugar transport regulation by signal sugar availability remain unclear in plant and animal cells. Here, we report that a sucrose transporter, MdSUT1, and a sorbitol transporter, MdSOT6...

On 16th of March 2008, temperature decreased to -6ºC in some parts of the Kerman pistachio plantation area that was caused the heavy damage to pistachio growers. After the damage, some rootstocks were resistance to this temperature and no damage was interned to them. In the present study five rootstocks of resistant and five rootstocks of susceptible to frost damage were selected and evaluated ...

Tocopherol cyclase, encoded by the gene SUCROSE EXPORT DEFECTIVE1, catalyses the second step in the synthesis of the antioxidant tocopherol. Depletion of SXD1 activity in maize and potato leaves leads to tocopherol deficiency and a 'sugar export block' phenotype that comprises massive starch accumulation and obstruction of plasmodesmata in paraveinal tissue by callose. We grew two transgenic St...

Soil salinization is more aggravating than ever before; suitable fertilizer application essential for promoting crop growth and productivity in saline soils. A field experiment was conducted to study the effects of different types fertilizers on oat (Avena sativa L.) associated physiological mechanism Two varieties (V1 = Baiyan 2 V2 7) were used four treatments (T1 control, T2 nitrogen fertiliz...

water salinity and drought are the major abiotic stresses limiting turf grass growth. on the other hand, shortage of waterresources and salinity of water and soil in the arid and semi-arid zones such as iran, are the restricting factors in developinglawn turf grasses. an experiment was conducted to evaluate the combined effects of water salinity and deficit irrigation ontall fescue (festuca aru...

to study the interaction effect of the salinity and salicylic acid on some morphological and physiological traits in clary sage (salvia sclarea), a pot experiment was conducted as factorial based on a completely randomized design with three levels of nacl and control (zero, 50, 100 and 150 mm), as the first factor and three levels of spraying the solution of salicylic acid and control (zero, 10...
