understanding of physiological responses of salt tolerance might be lead to identify main salt tolerance mechanisms and essential approaches for improving grain yield stability, and also to select salt tolerant wheat cultivars. thus, the effects of salinity were investigated on grain yield and some of the characteristics related to salt tolerance. six wheat cultivars (roshan, kavir, karchia, ga...

in order to evaluation of morphological selection criteria for salt tolerance screening in wheat (t. aestivum l.) a factorial experiment based on completely randomized design in 3 replications were conducted under greenhouse condition. salinity treatments involved 4 levels: s=1.3dsm-1 (control), 5, 10, 15 dsm-1 from calcium chloride and sodium chloride with 10:1 (na: ca ratio) and another facto...

Ameliorative effect of exogenously applied glycinebetaine (GB) on photosynthetic capacity of two wheat cultivars differing in salt tolerance grown under salt stress was assessed. Plants were grown under field conditions at 2.84, 15 dS/m in split-split plot design. Different levels of GB (no spray NS, 0.1% Tween 20 solution, 50 and 100 mM GB in 0.1% Tween 20 solution) were exogenously applied as...

Establishment of seedlings at early growth stages of crop plants as one of the most important determinants of high yield is severely affected by soil salinity. Therefore, high germination rate and vigorous early growth under saline soils is preferred. In this study 15 wheat (Triticum aestivum L.) cultivars were used to investigate the effects of three salinity concentrations including 4, 8 and ...

Effect of various NaCI treatments (0, 50, 100, 200 and 300 mM) at different growth and development stages (tillering, boot swollen, flowering and anthesis) of two wheat cultivars  on the kinetic activity and PAGE electrophoretic pattern of leaf malate dehydrogenase was studied under greenhouse conditions. Ghods was salt-sensitive and Boolani was salt-tolerant. In general, in response to salinti...
