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 ...

BACKGROUND Because soil salinity is a major abiotic constraint affecting crop yield, much research has been conducted to develop plants with improved salinity tolerance. Salinity stress impacts many aspects of a plant's physiology, making it difficult to study in toto Instead, it is more tractable to dissect the plant's response into traits that are hypothesized to be involved in the overall to...

stevia rebaudiana bertoni is a medicinal, perennial and herbaceous plant from asteraceae family with sweet glycosides in its leaves. salinity stress is one of the important limiters in agricultural productions. salinity influences the growth and development of plant by effect on more activities in physiological and morphological characteristics. to study the effect of salinity on morphological ...

Salinity of soil is a major abiotic stress limiting the crop production and growth of peppermint. The aim of study was assessment the plant growth regulators efficacy (salicylic acid (SA), jasmonic acid (JA), brassinosteroids (BRs), and non-application of hormone as control) on physiological traits of peppermint under salinity stress (0, 30, and 60 mM). The experiment was conducted using the co...

Taking into account the high potential of cyanobacteria to tolerate salinity stress, researches have evaluated the morphological and physiological behavior of these microorganisms in recent years. This study is conducted to investigate the impact of different concentrations of NaCl on the morphological and physiological traits of Nostoc sp. ISC 101. Biometrical and morphological observations ar...

The huge variation in root system architecture (RSA) among different rice (Oryza sativa) cultivars is conferred by their genetic makeup and different growth or climatic conditions. Unlike model plant Arabidopsis, the molecular basis of such variation in RSA is very poorly understood in rice. Cultivars with stable variation are valuable resources for identification of genes involved in RSA and r...
