“…We found that addition of 150 mM NaCl to the growth medium for 15 days affected differently the PM lipid and protein content and composition of the two maize cultivars contrasting in their response to salinity. Reports indicate that Cl -toxicity is the main cause for salt sensitivity in maize (Zidan et al 1992;Cramer et al 1994;Mansour et al 2005). Mansour et al (2005) find greater Cl -content in Trihybrid 321 as compared with Giza 2.…”

Two contrasting maize (Zea mays L.) cultivars, i.e., Giza 2 (salt tolerant) and Trihybrid 321 (salt sensitive), were grown hydroponically to study NaCl effect (100 mM) on root plasma membrane (PM) lipid and protein alterations. The PM total sterols of Trihybrid 321 were decreased while that of Giza 2 was increased in response to salt. Salt imposition had no significant effect on PM total glycolipids and proteins of both cultivars. The PM total phospholipids were increased in Trihybrid 321 but it did not change significantly in Giza 2 after salinity stress. Molecular percentage of PM phospholipids and fatty acids of both cultivars was different in absence (0 mM) and presence (100 mM) of salt. The most abundant phospholipids in untreated Trihybrid 321 PM were phosphatidylglycerol (PG), phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylserine (PS), which changed into PG, PS, phosphatidylinositol (PI) and PC after salt treatment. However, the dominant phospholipids of the control PM of Giza 2 were PC, PE, PS and PG, which changed into PG, PE, PS and diphosphatidylglycerol (DPG) after salt imposition. Over 60% of the total fatty acids were saturated in control and salinized PM of both cultivars, which was increased after salt stress. The predominant fatty acid in the control and salinized PM of Trihybrid 321 was C18:1 and C17:0, respectively. However, in control and treated PM of Giza 2, the predominant fatty acid was C17:0 and C20:0, respectively. Qualitative and quantitative differences in PM protein patterns were found in both cultivars with and without salt. PM lipid changes enhanced membrane integrity, reflected in different ion accumulation (Mansour et al. 2005), and hence salt tolerance of Giza 2.

“…Salinity stress was reduced to some extent by application of nutrient solution. Chemical analysis of the shoot samples from plants grown in saline soltions will be needed to confirm this, even though an earlier report by Zidan et al (1992) has shown that salinity does not inhibit the absorption of essential mineral nutrients by maize (Zea mays L.). In peanuts (Arachis hypogaea L.), however, Silberbush and Lips (1988) observed that a steady supply of N to the plants inhibited reduction in growth caused by NaCl.…”

The effect of salinity on biomass production, nodule formation and root acetylene reduction activity (ARA) in alfalfa (Medicago sativa L.) was investigated under field conditions. Seeds of alfalfa cv. Batini inoculated with one of four different Rhizobium strains were planted in washed loamy sandfilled transparent PVC cylinders arranged concentrically in plastic pots embedded in soil with the rims just above the soil surface. Salinization of plants commenced one week after emergence up to 16 weeks. Nitrogen (N)-free nutrient solutions of different concentrations (full strength and 0.05 strength) were also applied during this period. Tap water (0.8 dS nr 1 ) served as control for the nutrient solution treatments as well as the salinity treatments which included 6.4 dS m 1 and 12.2 dSnr 1 prepared with NaCl. The Rhizobium 'Corresponding author. 489 strains were TAL 380, TAL 1372, TAL 1373, and Buraimi. Increased salinity was associated with reduced shoot dry weights, root nodulation and ARA. Of the four Rhizobium strains, the order of efficiency in nodulation was Buraimi > TAL 1372 > TAL 1373 > TAL 380. This order was maintained in biomass the production. The detrimental effects of salinity appeared to be ameliorated by application of nutrient solutions, with the full strength being more effective than the 0.05 strength.

“…Like other growth parameters leaf area per plant also differed significantly across various salinity levels. Reduction in leaf area occurs either due to reduction in leaf number (Huang and Redmann, 1995) or leaf size (Zidan et al, 1992) and mostly as a result of reduction in both these parameters (Kayani and Rahman, 1988). Results inferred during this study resemble third category where a reduction in leaf area may be attributed to smaller and significantly lesser number of leaves.…”

Two maize inbreds (B-73 and MO-17) and their hybrid (YHS-202) were subjected to NaCI salinity induced at four growth stages in a pot experiment during 1998. It comprised of three salinity treatments viz. 10, 15 and 20 dSmG 1 alongwith control having normal field soil (EC 2.5 dSmG 1). A progressive decrease occurred in all parameters with increasing salinity levels. Grain yield was reduced by 22 percent at 20 dSmG 1 as compared with control. Salinity affected all the genotypes but MO-17 proved comparatively better than other two. Deterioration was caused by salinity at all growth stages but it was more pronounced at earlier than later growth stages.
