this research was performed to investigate the combined effect of soil salinity and compaction on some physiological characteristics of corn. for this purpose a factorial pot experiment on the basis of completely randomized design with three replications was performed. the experimental factors were three levels of soil salinity (saturated paste extract electrical conductivity 1.5, 2.5 and 4.5 d...

In this study, effect of salinity with different osmotic potential on shoot length, total fresh and dry weight, amounts of organic (proline) and inorganic (K+ and Na+) substance of leaf tissue, the Na+/K+ ratio, and leaf area, relative water content (RWC) and leaf osmolality in two maize (Zea mays L., var. intendata, C.6127 and DK.623) cultivars which are grown as a second yield in the Southeas...

The Panax ginseng TIP gene PgTIP1 was previously demonstrated to have high water channel activity by its heterologous expression in Xenopus laevis oocytes and in yeast; it also plays a significant role in growth of PgTIP1-transgenic Arabidopsis plants under favorable conditions and has enhanced tolerance toward salt and drought treatment. In this work, we first investigated the physiological ef...

BACKGROUND AND AIMS Since salinity and drought stress can occur together, an assessment was made of their interacting effects on leaf water relations, osmotic adjustment and net gas exchange in seedlings of the relatively chloride-sensitive Carrizo citrange, Citrus sinensis x Poncirus trifoliata. METHODS Plants were fertilized with nutrient solution with or without additional 100 mm NaCl (sal...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

Soil alkalinity is a severe threat to crop production globally as it markedly retards plant growth. Different techniques are used mitigate alkaline stress, but priming considered the most appropriate. The current study was carried out in complete randomized design (CRD) evaluate effect of different on maize grown under levels stress. experiment comprised treatments stress (AS) including, contro...

The effect of four water salinity levels (0.75, 5, 10 and 15 dS.m -1 ) on growth indices and physiological parameters in some wild pistachio (P. atlantica, P. atlantica subsp. kurdica, P. atlantica subsp. mutica and P. atlantica subsp. cabulica) were investigated under greenhouse conditions. Leaf dry weight was reduced to about 30-54% at ECw 10 dS.m -1 . Chemical analysis of shoot and root indi...
