In order to investigate the effect of different levels of Copper (Cu) and Zinc (Zn) on morphological traits of dragon’s head, concentration of Cu, Zn, Fe, Mn, P and K in root and shoot and concentration of Cu and Zn in infusion and decoction, a greenhouse experiment was conducted as factorial based on complete randomized design with three replications. Treatments consisted of three levels of Cu...

Salinity is one of the most important restricting factors for plant growth and production around the world. The use of plant growth regulators has been expanded for improving salt tolerance in recent decades. In this investigation the effect of gibberellic acid (GA) and paclobutrazol (GA inhibitors) were evaluated for ameliorating negative effects of salt stress in sweet sorghum. After germinat...

Endophytic fungi as the most important soil microorganisms through establishing a symbiotic relationship with various plants play an important role in improving growth and mineral nutrition of their host plants. This research investigates the effect of Piriformospora indica and mycorrhizal fungi treatments on phosphorus efficiency indices and increasing phosphorus deficiency tolerance stress in...

Nowadays, cultivation of medicinal plants in the greenhouse and use of appropriate strategies to improve the response to environmental stresses on one hand, and growth of medicinal compounds on the other hand, has been under consideration. In this research, effect of exogenous putrescine on resistance of Datura stramonium plant to salinity stress was evaluated through studying growth parameters...

In order to study the effects of salinity stress on morphological traits, essential oil content and ion accumulation in basil (Ocimum basilicum) plant under hydroponic conditions, a factorial experiment based on completely randomized blocks design with three replications was conducted on three landraces (Jahrom, Banafsh and Isfahan) and five NaCl salinity levels (0, 40, 80, 120 and 160 mM) in c...

In order to evaluate the salinity and priming effects on vegetative growth and some physiological traits of safflower, cv. Goldasht, a factorial experiment, with completely randomized blocks design and 4 replications, was conducted in Research Greenhouse of Vali-e-Asr University of Rafsanjan in 2009. Treatments included seed priming at 4 levels (no prime as control, priming with distilled water...
