Temperature, humidity and precipitation in an area, are parameters proved influential in the climate of that area, and one should recognize them so that he can determine the climate of that area. Climate changes are of primary importance in climatology, and in recent years, have been of great concern to researchers and even politicians and organizations, for they can play an important role in s...

The seedless barberry, ‘Bidaneh,’ is one of the most important cultivated small fruits in Iran. This cultivar propagated only by suckers, and so, establishment large-scale orchards not...

frost in early spring is one of the limiting factors in the production of grape. chemicals offer useful approach to reduce low temperature-induced damages. different concentrations of salicylic acid including: 0 (control), 0.5, 1 and 2 mm were sprayed twice on 10 year-old ‘bidaneh sefid’ grape vines at full bloom stage and changes in leaf soluble carbohydrates, proline and protein levels were m...

Expression patterns of four candidate AREB/ABF genes and four DREB/CBF genes were evaluated in leaf and root tissues of five grape varieties ('Qalati', 'Kaj Angoor', 'Sabz Angoor', 'Siahe Zarghan', 'Bidane Safid') with differential response to drought stress. Among the AREB/ABF genes, AREB1 and ABF2 showed up-regulation in response to drought stress in leaf and root tissues of all varieties whi...

vineyard management, plant nutrition, irrigation, genotype and pests and diseases are effective factors quantity and quality of crops. among mentioned factors, plant nutrition has more importance and nutrient imbalance in soil can affect crop quantity and quality. grape cluster necrosis at veraison time is important disorders in vineyard, because of lack of balance between potassium and magnesi...

Salicylic acid (SA) plays an important role in the regulation of plant ripening and responses to abiotic stresses. In this study, the protective effect of SA on cold stress-caused oxidative damage in grape (Vitis vinifera L.) bunches was investigated during cold storage.  Grape bunches treated with 2 mM SA and  stored at 0°C with 85-90% RH for 30 days. Samples were selected from each treatment ...

thrips tabaci is one of the most important pests causing serioues damages on onion s in iran despite several chemical sprayings. to assess the population density and damage of the thips on onion, improved sefid-e-khomein genotype along with seven other iranian cultivars of onoin were planted in a rcb design with four replications in two separate experiments (sprayed and non-spray ed ) in arak f...

thioredoxins (trxs) are small heat-stable proteins that are involved in the cell redox regulation and are present in all organisms from prokaryotes to higher eukaryotes. in higher plants, trxs can be classified into six different groups namely: the chloroplastic trxs f, m, x, and y, the mitochondrial trx o and the trxs h. the trxs h are represented by a small multigenic family that participate ...
