“…Maize and rice crops were allowed to grow at an average daynight temperature (26±4 °C and 18±3 °C). Salt stress was applied to twenty-one-day old seedlings each day by using 25 mM NaCl to achieve the desired level (Gorham et al 1987) and moisture contents were maintained with tap waand moisture contents were maintained with tap water. Three NaCl concentrations (50, 100 and 150 mM NaCl) were applied.…”

-The physiological response of crop plants against Trichoderma harzianum (Th-6) in a saline habitat was studied. Trichoderma harzianum (Th-6) is an endophytic fungus that shows salt tolerance and establishes a symbiotic relationship with a host plant. To evaluate the role of Trichoderma harzianum (Th-6) in mitigating the consequences of salinity stress on crop plants, seeds of maize and rice were coated with Trichoderma before sowing and salt treatment. Later, after germination, twenty-one day old seedlings were subjected to NaCl concentrations (50, 100 and 150 mM). Salinity negatively affected all investigated physiological parameters in both crops. Treatment of seeds with Trichoderma improved plant growth and Th-treated plants exhibited substantial physiological adjustment in a saline environment compared to Th-untreated plants. The Th-treated plants under salt stress showed higher relative water content and stomatal conductance, better photosynthetic performance and higher pigment concentrations, as well as higher catalase and superoxide dismutase activities. Moreover, proline content in salt stress environment was higher in Th-treated plants, while H 2 O 2 content declined. The physiological role of Trichoderma harzianum in mitigating the salt related consequences of both crop plants is discussed.

“…Durum wheat is a salt-sensitive species and germination and seedling stages are the most critical phases for plant growth under salinity (Flagella, Trono, Pompa, Di Fonzo, & Pastore, 2006). Its sensitivity to salt stress is higher than bread wheat, due to a poor ability to exclude Na + from the leaf blades, and a lack of the K + /Na + discrimination character displayed by bread wheat (Gorham, Hardy, Jones, Joppa, & Law, 1987;Lauchli, James, Huang, McCully, & Munns, 2008). However, a novel source of Na + exclusion has been found in an unusual durum wheat genotype named Line 149.…”

“…Some of the effects we observed could be accounted for by the action of known genes such as the cer series, which occur on all chromosomes (Sogaard & von Wettstein-Knowles, 1987), as levels of epidermal wax are modified by salt stress. Genes on chromosome 4 are also important as this is where a number of relevant functions have been located; salt tolerance (Eorster et al, 1990), Na/K discrimination (Gorham et al, 1987). However, more detailed studies are required to decide which of these genes has the most important effect and this is best done in specially selected lines of known genotype.…”

SUMMARYAmplified fragment length polymorphisms (AFLPs) offer a reproducible, multiplex DNA assay by which to genotype mapping populations. We have evaluated physiological traits in barley seedlings grown in an hydroponic system and given a salt treatment. Multiple regression was used to show associations between AFLPs and quantitative traits. Effects at different loci were detected in stress treatments in comparison to the control implying that either novel gene action was induced by salt stress or that normal activity was reduced to a low level where alternate gene action is revealed. The QTLs occurred on all chromosomes but there appeared to be clusters of loci on chromosomes 1 (7H), 4 (4H), 5 (lH) and 6 (6H). The significance of our results is discussed in the context of studies to explore the barley genome and the application of the results of these genetical analyses to barley breeding.
