this study was carried out in the general commission for scientific agricultural research (gcsar) at der ez zour agricultural research center, during 2009- 2010 growing seasons. the role of na+, k+, na+/k+, carbohydrates accumulation of leaves, and sugar content of roots on the osmotic adjustment was studied in 10 sugar beet genotypes (five were monogerms and five were multigerms), under salini...

Atriplex canescens (fourwing saltbush) is a C4 perennial fodder shrub with excellent resistance to salinity. However, the mechanisms underlying the salt tolerance in A. canescens are poorly understood. In this study, 5-weeks-old A. canescens seedlings were treated with various concentrations of external NaCl (0-400 mM). The results showed that the growth of A. canescens seedlings was significan...

a factorial experiment based randomized complete block was conducted in order to investigation of two rice (oryza sativa l.) genotypes responses for na+, k+, ca2+, mg2+, clˉ, mn2+, p and total soluble sugars accumulation and compartmentation in leaves 3, 4, 5 and 6 to salt stress. in estimation of the simple correlation between traits, dry weight was negatively correlated with na+ and clˉ. the ...

To determine if salt tolerance of grafted cucumber can be associated with the accumulation of organic solutes and inorganic solutes in the leaves and roots, a salt-sensitive cucumber cultivar Jinchun No. 2 (Cucumis sativus L.) was grafted onto the commercial salt-tolerant bottle gourd cultivar Chaofeng 8848 (Lagenaria siceraria Standl.). Grafted and ungrafted plants were grown in hydroponic sys...

Salinity is one of major stresses which can severely limit plant production, especially in the arid and semi-arid regions. The present study was carried out to evaluate the impact of salinity stress on some physio-biochemical parameters in nitre bush plants (Nitraria schoberi). Thus, an experiment was carried out under natural conditions and salinity stress was induced by a combination of diffe...

in this study, we assessed the relative contribution of organic and inorganic solutes to osmotic adjustment (oa) in three almond rootstocks subjected to four levels of soil salinity. the results showed that leaf water and osmotic potentials were affected by salinity in gf677 and bitter almond, but less so in gn15, suggesting a higher selectivity for k+ and ca2+ against na+ in this latter rootst...

a greenhouse experiment was carried out to evaluate the effects of salinity stress on growth and macroelements contents of two olive varieties under hydroponic conditions. in the research, one-year old saplings of two olive varieties, ‘zard’ and ‘mission’, were subjected to different salinity levels induced by nacl including 0, 4, 8, 12 and 16 dsm-1 for 5 months. based on the results, total dry...

To investigate the effects of saline stress on seed germination, ion distribution, and organic solutes changes of sunflower (Helianthus annuus L.), in the present study, seeds and 3-week-old seedlings were subjected to a series of external NaCl concentrations (5–200 mmol). The results showed that high salinity (200 mmol) remarkably inhibited the germination of seed and delayed germination time ...

To study the variation of plant traits related to stress tolerance in tolerant and sensitive barley cultivars under salt stress conditions, an experiment was carried out as factorial arrangements in completely randomized design in Payame Noor University of Mahabad, Iran in 2018. Application of salinity stress of 250 mM of sodium chloride started from tillering stage, and leaf samples were taken...
