to evaluate the effect of different levels of drought stress on some physiological parameters in strawberry, potted experiment involing strawberry cultivars  ‘marak٫ , ‘camarosa٫ and ‘gaviota٫ was conducted during summer 2009. the experiment consisted of three drought stress levels in three replications. the experimental arrangement was a factorial one, based upon a randomized complete block de...

To decrease adverse effects of water deficit is foliar application with chemical agents such as silicon. However, there is low information on the influence of silicon on alfalfa under drought stress conditions. Thus, the current study was conducted to assessment the effect of different silicon concentrations (0, 1 and 2 mili Molar concentration) on alfalfa growth trend and biochemical traits, w...

in order to study the effect of light quality and quantity on morphological and physiological characteristics of two late and early maize (zea maize l.) s.c., an experiment was conducted in greenhouse conditions, ferdowsi university of mashhad, iran, during 2008. the experiment was carried out factorial based on randomized complete block design with six treatments and three replications. differ...

The ch4 mutant of sweetclover (Melilotus alba) has previously been demonstrated to be temperature- and photoperiod-sensitive for the accumulation of chlorophyll. Pigment content of ch4 mutant leaves was examined as a function of trifoliolate mass, an index of leaf development. Inhibition of chlorophyll accumulation caused by increased growth temperature or decreased photoperiod can be attenuate...

physiological study of wheat varieties under abiotic stress conditions is a very important factor for improving their future productions. this research work was conducted in the research greenhouse of faculty of agriculture, tarbiat modarres university in 2006, to study leaf quantitative traits of durum wheat under different levels of carbon dioxide (400 and 900 ppm), ultraviolet radiation (uv ...
