Five alfalfa (Medicago sativa L) cultivars from different areas of Iran were evaluated for oxidative markers under salinity conditions. Plants were grown in hydroponic condition by Hoagland nutrient solution containing different amounts of NaCl (control, 50 and 100 mM). Relative growth rate, membrane stability, lipid peroxidation, proline, hydrogen peroxide and relative water contents were dete...

Hydroponic systems are efficient for studying plant nutrition. It is often desirable to adjust individual nutrients unique species’ needs and/or create multiple nutrient deficiencies within the same study. However, this challenging do with traditional solutions as generally added dual salts, such when varying phosphorus (P) concentration also affects nitrogen concentration; potentially, chemica...

to study the effect of different concentrations of potassium in thenutrient solution and water stress on the quality and quantity yield of lilium la cv.termoli, a pot experiment was conducted based on completely randomized design in sand and perlite medium (50:50) in three levels of potassium (kfree, 6 mm k and and 12 mm k in hoagland solution) with three replications. in the present study, the...

information of heavy metal toxicity about physiological aspect of lettuce is limited. therefore an experiment was conducted in crd designed with 7 replications on lettuce (lactuca sativa l.). treatments were cadmium in 3 concentration (0, 2 and 4 mg/l) added to hoagland solution. results were shown that increasing in cadmium of nutrient solution caused increasing in sod, pod antioxidant and pro...

To study the effect of different concentrations of potassium in thenutrient solution and water stress on the quality and quantity yield of Lilium LA cv.Termoli, a pot experiment was conducted based on completely randomized design in sand and perlite medium (50:50) in three levels of potassium (Kfree, 6 mM K and and 12 mM K in Hoagland solution) with three replications. In the present study, the...

The increasing release of untreated fish farming effluents into water courses that flow to the Pantanal wetlands in Mato Grosso (Brazil) may drive this ecosystem to eutrophication. Therefore, the growth of Azolla caroliniana Willd. and Salvinia auriculata Aubl. in fish farming effluent and their effect on its quality were evaluated for 48 days in a greenhouse. The results were compared to those...

The role of molybdenum (Mo) and copper (Cu) in regulation the activities of the enzymes involved in primary nitrogen assimilation in particular the nitrate reductase (EC 1.6.6.1) and glutamine synthetase (EC 6.3.1.2) was examined. Pea plants were grown in a phytotron chamber at 12 h photoperiod, day /night temperature 25/18 C and photon flux density of 95 μmol m s until 21 day. Plants were grow...
