Lippia citriodora H.B.K. is a valuable medicinal plant of Verbenaceae family. This study was calculated to evaluate potential role of salicylic acid (SA) in diminish the harmful effects of drought stress on L. citriodora plants. SA (0.5 and 1 mM) was used to L. citriodora plants grown under stressed (5, 10, 15 and 20% PEG) and unstressed conditions. Fresh weight (FW) and relative water content ...

In order to evaluate the tuber fresh weight and some physiological attributes of Agria potato cultivar in response to water deficit stress and mycorrhiza inoculation, a field trial was conducted as a split plot scheme based on randomized complete block design with three replications at the research site of Islamic Azad University, Tabriz Branch in 2012. Four water levels including: irrigation a...

in order to study the sensitivity of vegetative growth to water deficit stress of a late-maturing peach (prunus persica l. cv. elberta) under orchard conditions, an experiment was conducted as randomized complete-block design with three treatments and four repetitions in shahdiran commercial orchard in mashhad during 2011. three irrigation treatments including 360 (low stress), 180 (moderate st...

PURPOSE Impairment of learning and memory processes has been demonstrated by many studies using different stressors. Other reports suggested that exercise has a powerful behavioral intervention to improve cognitive function and brain health. In this research, we investigated protective effects of treadmill running on chronic stress-induced memory deficit in rats. METHODS Fifty male Wistar rat...

Water is the most limiting factor for plant growth and crop productivity (Kramer, 1983), and water-deficit stress adversely affects crop growth and yield throughout the world (Boyer, 1982). Crop yields are being reduced by drought and the increasing scarcity of water for irrigation, and changing world climatic trends may increase the severity of the problem (Le Houerou, 1996). Water availabilit...

effects of seed priming by salicylic acid on yield and yield components of cowpea (vigna unguiculata) cultivar “parastou” were investigated under water deficit conditions. experiment was carried out as a split block design with three replications in 2008-2009 at research station of zanjan university. factors included drought stress as main factor with three levels (normal irrigation, applicatio...

abstract- the crop water stress index (cwsi) is the most common index to monitor and assess crop water stress, based on canopy temperature. to calculate cwsi, upper and lower baselines adaptable to different environments are needed. in this study, empirical and theoretical limiting baseline equations were developed to determine eggplant cwsi values at different levels of water deficit and salin...
