salt stress is one of the most chalanging abiotic stresses affecting natural productivity and causing significant croplosses worldwide. a greenhouse experiment was conducted to evaluate the response of two alfalfa cultivars (bamiand hamedani) to 6 levels of salinity (0 as control, 25, 50, 75, 100, 125 mm nacl) at the college of agriculture,shiraz university, shiraz, iran in 2008. plant dry weig...
Chloride is an essential micronutrient for plants growth however it accumulates in large amounts in tobacco plants rapidly. To evaluate the effects of chloride concentrations in irrigating water on yield and growth indices of tobacco plant which has an important economic value, an outdoor pot experiment was established in completely randomized design during 2010 crop year at Guilan Tobacco Rese...
In a three-year (2004-2006), field experiment, we aimed to study changes in leaf physiological traits (leaf water potential-Ψleaf, leaf water content-LWC, carbon isotope discrimination-Δ, specific leaf area-SLA, chlorophyll content as assessed by SPAD and modified SPAD-MSPAD) and elemental composition (K, Na, Ca, Mg, K/Na, Ca/Mg, total leaf salinity-TLS) of sugar beets (cv. Rizor) grown unde...
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
An experiment was carried out to evaluate the effect of various concentrations of Mg (0, 1, 2, 3 and 4 mM) in the nutrient solution and shading (0 and 50%) on growth, yield, fruit quality and physiological properties in hydroponically grown cucumber (Cucumis sativus L. cv. Nagen 792). With increased Mg concentration in both shaded and unshaded plants, the total plant leaf area and dry weight of...
In order to investigate the effect of Piriformospora indica endophyte fungi on quantity and quality of peppermint essential oil and physiological parameters under salt stress, An Research Field experiment of Agricultural Sciences and Natural Resources University of Surrey in 2015 was conducted. Experiment arranged in completely randomized design with three replicates. The experiment was done in...
dry land salinity is one of the major problems affecting agricultural products. the main consequences of plant exposure to salt stress are water deficit and ion excess, which lead to several morphological and physiological changes. in order to evaluate the effect of salinity on some physiological characteristics of 8 spring rapeseed cultivars, an experiment was conducted in the greenhouse at ya...
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 sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
in order to evaluate of morphological, physiological and biochemical traits, related to drought tolerance, an experiment was carried out in field condition. in this study two commercial cultivars (mcc361, mcc358), three kabuli and three deci type of tolerant genotypes (mcc392, mcc537, mcc696, mcc873, mcc870, mcc10,) and three kabuli and three deci type of susceptible genotypes (mcc759, mcc588, ...
