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 ...

in order to study the response of coriander medicinal plant to salt stress, two experiments were conducted for germination and vegetative stages. this study was carried out as a factorial experiment based on completely randomized design with three replications. the treatments were salinity at five concentrations including 0, 25, 50, 75 and 100 mm nacl. response of coriander seeds germination in...

The inhibition of fructan accumulation by phosphate was investigated in warm-grown and cold-treated barley (Hordeum vulgare) plants. Detached leaves were incubated in water or phosphate for 24 h under lighting or in darkness. Fructosyltransferase, sucrose phosphate synthase (SPS) and cytosolic fructose-1,6-bisphosphatase (FBPase) activities were subsequently analysed, as well as the content of ...

The effect of wilting on proline synthesis, proline oxidation, and protein synthesis-all of which contribute to proline accumulation-was determined in nonstarved barley (Hordeum vulgare L.) leaves. Nonstarved leaves were from plants previously in the light for 24 hours and starved leaves were from plants previously in the dark for 48 hours. Wilted leaves from nonstarved plants accumulated proli...

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...

Magnesium (Mg) deficiency exerts a major influence on the partitioning of dry matter and carbohydrates between shoots and roots. One of the very early reactions of plants to Mg deficiency stress is the marked increase in the shoot-to-root dry weight ratio, which is associated with a massive accumulation of carbohydrates in source leaves, especially of sucrose and starch. These higher concentrat...

Bermudagrass [Cynodon dactylon (L.) Pers.] is a perennial grass and has been long used as a medicinal herb in Iranian traditional medicine to treat varied ailments. Different parts of bermudagrass such as leaves, stolons, rhizomes and culms are rich sources of metabolites such as proteins, carbohydrates, mineral constituents, β-sitosterol, flavonoids, alkaloids, glycosides and triterpenoides. G...
