Extended Abstract Introduction: The germination stage ensures the durability, establishment, and final yield of plants.  The final density of plants per unit area is resulted when the planted seeds germinate fully and with adequate rate. Plants mainly undergo abiotic stresses that are a considerable constraint for agricultural production worldwide. Seed priming is one of the simplest and cheap...

Nickel is  an essential microelement for plant growth, but upper levels of this element serve as heavy metal  which create toxic effects on plants and human. Application of mineral nutrition is a useful strategy for overcoming of this serious problem.  In order to investigate the effects silicon nutrition on growth and physiology indices of basil (Ocimum basilicum L.) under nicke...

Using bacteria for producing plant nutrients, applying proper methods of soil fertility, and nutrition of plants, other than preserving environment and human health, eliminates unnecessary and wasteful use of chemical fertilizers. Thus, in order to achieve this aim, a greenhouse experiment was carried out, based on completely randomized design with three replications, in Damavand city, during 2...

Production of medicinal crops in soilless culture systems and controlled environments provides an opportunity for increasing the quantity and quality of primary materials of medicinal plants. A factorial experiment based on completely randomized design was carried out with four culture systems (aeroponics, nutrient film technique, classic hydroponics and soil) and three different nitrogen sourc...

Drought stress is one of the most important and most common environmental stress that is limited agricultural production. to evaluate the effect of different levels of deficit irrigation on some properties of three varieties of petunia, a factorial experiment in a completely randomized design with four replicationswas conducted in research greenhouse of Ferdowsi University of Mashhad. Examined ...

Abstract: Drought stress is considered as a limiting factor for plant productions therefore, many compounds have been applied to minimize the harmful effects of stress. In this study, the effect of paclobutrazol, a triazole growth regulator, on morphological and biochemical parameters of Brassica napus L. under in vitro drought stress was investigated. First, the seeds of B. napus L....

Background and objectives One of the main causes of plant growth and development disorders is the presence of adverse environmental conditions such as drought, which leads to stress in plants and endangers their survival. Recent research, however, recommends the use of soil microorganisms, especially plant growth-promoting bacteria, which are involved in plant growth as well as the nutrient cy...
