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...

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...

This study was conducted to assess the effects of two species of arbuscular mycorrhiza fungi (Glomus mosseae and G. intraradices) on growth of young plantlets of two olive cultivars (Koroneiki and Valanolia). Recently rooted cuttings were inoculated with the mycorrhiza, planted in pots containing sterile soil and located in the greenhouse. Eighteen months following inoculation, some morphologic...

Soilless culture in greenhouse is being developed in Iran, as in many countries of the world. This study was conducted to evaluate the possibility of applying sawdust as well as the effect of adding bentonite and pumice on vegetative growth of bell pepper cv. Inspratian. The experiment was conducted as a completely randomized blocks design with 8 treatments and 4 replications, in greenhouse of ...

Antimony (Sb) pollution has increased in recent years because of human activities and extensive usage of antimony compounds. To date, only a few researches have been conducted in this field in Iran. The purpose of this research is to determine fresh and dry weight, root permeability percentage and root concentration of Sb, Fe and Zn in the corn. This greenhouse research was performed in hydropo...
