Triticum aestivum L. and Zea maize L. are both sensitive to salinity stress which is a major problem faced by farmers today. In the present study, the effect of chitosan, a biologic elicitor under salinity stress was examined on growth parameters and biochemical markers in maize and wheat s...

A field experiment was carried out to study the response of presoaked faba bean seeds (Vicia faba cv. Misr 2) in freshly prepared ascorbic acid (50 ppm) or distilled water (control) for 4 hrs at natural environmental conditions, to salinity stress. NaCl treatments caused a reduction in all productivity and yield parameters as compared with control, particularly at high NaCl level (150 mM), wher...

High carbon dioxide (CO2) concentration in atmosphere has direct effects on plants activities. In order to investigate the effect of increased CO2 concentration from 380 to 700 and 1050 mg/L on some chemical and physiological characteristics of Amaranthus tricolor under three salinity treatments (0, 150, and 300 mM NaCl), an experiment was conducted in Research Greenhouse of Ferdowsi University...

For the purpose of evaluating the effect of chitosan on seed germination and some biochemical characteristics of the milk thistle herb in the conditions of salinity, an experiment was conducted as factorial in a completely randomized design (CRD) with three replications in the Laboratory of Seed Science and Technology of Shahed University, Tehran in 2015. Experimental factors comprised salinity...
