in this research the effects of crude oil on morphological and physiological characterization ofthe cyanobacterium microchaete tenera isc13 were investigated. isolated cyanobacterium treated with different oil concentrations (control, 1, 2.5, 5 and 7%) in carbonless bg110 medium. morphological characteristics such as morphology of filament, cellular shapes and sizes, relative position of hetero...

Th e most of previous studies have been focused on the eff ect of water stress on plant yielding. However, the conditions in which plants grow from the moment of planting might aff ect their morphology and physiological response. Th e aim of this study was to examine the eff ect of water defi ciency on growth and plant physiological response of strawberry (Fragaria x ananassa Duch. cv. ‘Salut’)...

Flooding is a natural disturbance affecting crop and forage production worldwide due to the detrimental effects that it provokes on most terrestrial plants (Bailey-Serres & Voesenek, 2008; Colmer & Vosenek, 2009). Over the last years, the Intergovernmental Panel on Climate Change (http://www.ippc.ch) has informed that man-induced world climate change will increase the frequency of precipitation...

Selective herbicides have been used for weed control since the turn of the century, but the use of 2,4-dichlorophenoxyacetic acid (2,4-D.) has developed during the past decade. This chemical is valuable because numierous broadleaved weeds are susceptible to low rates of application and mnany agronomic crops are tolerant to these small dosages. Barley has been considered to be one of the relativ...

trifolium spp. are native plants in iran exhibiting good ground cover po-tential. salinity is a major environmental stress and today, 20% of the world cultivated areas and nearly half of all irrigated lands are affected by salinity. the main aim of this research was to study morphological and physiological adaptations of these native species under different salinity levels for urban landscape u...

to study some physiological and morphological traits of sugar beet varieties in response to salinity stress, three multi-germ sugar beets (13030, 22393 and ic) were grown in the greenhouse, faculty of agriculture, shahid chamran university, in 2009. the experiment was carried out under three levels of salinity in from of sodium chloride source, that included control (zero), 100 and 200 mm uses ...
