abstract environmental pollution has made urban citizens to focus on landscapes. in this respect lown is very important plant. from the other hand water resources in many arid and semi-arid region is saline. for this purpose a research was conducted to study the effect of sprinkling irrigation with saline water on growth parameters of three lown varieties. these varieties were poa partensis, fe...

Salinity and drought often affect plant growth and crop yields. Cloning and identification of salinity and drought stress inducible promoters is of great significance for their use in the genetic improvement of crop resistance. Previous studies showed that phosphatidylinositol synthase is involved in plant salinity and drought stress responses but its promoter has not been characterized by far....

salinity is a major environmental problem in arid and semi-arid areas. chickpea (cicer arietinum l.), like other legumes is sensitive to salinity. therefore, selection of genotypes to grow on saline areas is important. eleven chickpea genotypes (as sub plots) were grown in the greenhouse conditions on a medium containing different nacl concentrations (8 and 12 dsm-1) and control (hoagland solut...

Studies of the future competitiveness of reverse electrodialysis (RED) with other energy technologies show that the projected levelized cost of electricity realized through current stack designs is prohibitively high. Despite these high projected costs, RED maintains other advantages namely, the harnessing of a renewable and non-intermittent energy resource, the emissions-free operation, the di...

abstract silicon (si) is considered one of the beneficial elements for plant, however recent studies show that si plays an important role in plant resistance to environmental stresses , like salinity. an experiment was conducted to study the effect of si and nacl salinity on the growth, yield and fruit quality of strawberry (fragaria × ananassa duch) cv “selva” was grown hydroponically in the c...

abstract millets are important agricultural crops for arid regions due to short life span and their resistance to salinity and drought conditions. in iran, three main species of millets including proso millet (panicum miliaceum), foxtail millet (setaria italica) and pearl millet (pennisetum glaucum) are cultivated in shouthern khorasan province, eastern iran. in order to assess inter-specific g...

The cytochrome P450 monooxygenases (P450s) represent a large and important enzyme superfamily in plants. They catalyze numerous monooxygenation/hydroxylation reactions in biochemical pathways, P450s are involved in a variety of metabolic pathways and participate in the homeostasis of phytohormones. The CYP82 family genes specifically reside in dicots and are usually induced by distinct environm...

Cynara cardunculus.L exhibits an important adaptability to arid and semi-arid regions where high salinity is frequently present. Aiming to introduce its cultivation in the Mediterranean environment especially in Tunisia, it seemed interesting to study seed germination of eight populations of cardoon in four concentrations of NaCl: 0g/L, 2g/L, 4g/L, and 8g/L. Our results showed a good variabilit...
