Cadmium (Cd) is one of the most toxic heavy metals in plants. To investigate whether Cd induces common plant defense pathways, different physiological and molecular reactions, including modifications in glutathione (GSH) level, activity and gene expression of glutathione reductase (GR) enzyme were characterized in roots of hydroponically cultivated-Vicia seedlings during 12, 24 and 48 h. Vicia ...

Short-term salt (NaCl) treatment on Aegiceras corniculatum in roots and leaves showed no change in fresh and dry weight of leaves, roots and leaf area. There was no significant change in total soluble root protein, photosynthetic pigments of leaves and spectral characteristics of thylakoids. However, the activity of antioxidative enzymes (catalase, ascorbate peroxidase and guaiacol peroxidase) ...

Roots are plant organs that function to absorb water and nutrients from the rhizosphere. If soil is dry, roots will be affected first. This study aims know response of soybean root drought stress. research was arranged in a randomized completely block design (RCBD) with two factors three replications. The first factor moisture content, which consisted four levels, e.i., 100, 75, 50, 25% field c...

Strawberry is considered as a salinity sensitive species and is adversely affected in response to the salt stress in terms of growth and yield. Pot experiments were conducted to determine the effect of exogenous salicylic acid (SA) application on physiology, growth, chlorophyll and mineral content of strawberry grown under salt stress and greenhouse conditions. Strawberry plants were treated wi...

In this research cyanobacteria (Blue-Green Algae, BGA) were isolated, identified, multiplied and used as an inoculum in pot rice experiment. The pH, moisture and algal population were measured in four seasons. The highest and lowest pH (6.7, 6.2), moisture of soil (43%, 34%) and algal population (12, 20 Colony-Forming Units/50 ml on A and B medium and 4, 5 Colony-Forming Units/50 ml on A and B ...

investigation of various irrigation methods and intercropping are effective strategies for increasing water use efficiency and improve crop production. a field experiment conducted to study the effects of alternate furrow irrigation on quantitative and qualitative characteristics of forage corn with annual alfalfa cropping under its canopy in ilam climate conditions. experiment carried out as a...

plants are the important sources of drugs. secondary metabolites are responsible for therapeutic propertiesin plants. three compounds including (-)-hyoscyamine, its racemate atropine, and scopolamine (hyoscine) are the most famous tropane alkaloids in the solanaceae familly. nowadays, attempts to developthese alkaloids in biotechnological procedures which are principally based on the hairy root...
