in order to study the effect of natural antitranspirant compound and water stress on growth, development and essential oil content of ocimumbasilicum a factorial experiment based on completely randomized design with three replicates was conducted. 3 levels of water stress (500 as control, 375 and 250 ml/day) and 3 antitranspirant compound (chitosan, plantago mucilage and psyllium mucilage) in 3...

exposure to stress leads to physiological changes called “stress response” which are the result of the changes in the adrenomedullary hormone system, hypothalamus-pituitary-adrenal (hpa) and sympathetic nervous system (sns) activity. in the present study, the effects of chronic physical and psychological stress and also the role of sympathetic system effects in stress on ischemia/reperfusion (i...

chickpea (cicer arietinum l.) is mainly cultivated in arid and semi-arid agricultural systems. drought stress is a major factor delimiting maximum yield. this research evaluated the effects of drought stress treatments on expression of cu/znsod as a gene involving in drought tolerance by real time pcr technique. to find the probable relationship between the molecular and physiological effects o...

objective: dietary changes playmajor risk roles in oxidative stress andcardiovascular disease and modulate normal metabolic function. the present study was designed to investigate the ameliorative potential of different extracts of hemidesmus indicus to experimental high-fat diet in wistar rats, and their possible mechanism of action.  materials and methods: male wistar rats were divided into 6...

water deficit stress permanent or temporary limits the growth and distribution of natural vegetation and performance of plants more than other environmental factors. in order to investigate the effect of drought stress and mycorrhizal-arbuscular fungi inoculation on the growth and yield of savory (satureja hortensis l.) a factorial experiment based on completely randomized design were conducted...
