Background: Elicitors can trigger defense responses and activate specific genes involved in secondary metabolite biosynthesis. Objective: For understanding SA-treatment signaling pathway we determined defense-related compounds and enzymes in S. marianum hairy root cultures. Methods: 28 day old hairy roots were treated by salicylic acid (6 mg/50 ml culture) for different times (24, 48, 72, 96...

In order to investigate the effect of drought stress and nitrogen application on growth and some physiological characteristics of sorghum genotypes, an experiment was conducted in a split-split plot with randomized complete block design in three replications at Research farm of collage of agriculture, Isfahan University of Technology. Experimental treatments consisted of two irrigation regimes ...

Nowadays, phenolic compounds and plant growth regulators such as salicylic acid has been prescribed to reduce the adverse effects of different stresses. This greenhouse experiment was conducted in 2013, as a factorial randomized complete block design with 3 replications, to examine the effects of lead and salicylic acid on basil (Ocimum basilicum) plant, cv. Keshkeni Luvelou. Factors included 4...

Smoke tree (Cotinus coggygria Scop.) is an attractive ornamental tree in landscape that has medicinal properties. In this study, the effects of different levels of salt, cow manure and vermicompost on plant growth were investigated. In a factorial experiment and completely randomized design (CRD), three levels of organic amendments (1- soil 2- 80% v/v soil + 20% v/v vermicompost, 3- 80% v/v soi...

A factorial experiment was conducted in greenhouse in a completely randomized design (CRD) with three replications to investigate the response of Zn-efficient and -inefficient bread wheat cultivars to soil Zn deficiency. The factors of the experiment were soil Zn levels (Zn-adequate: 5mg Zn kg-1 soil and no Zn application), Zn-efficient (Bayat and Niknejad) and -inefficient (Hirmand and Karaj1...
