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...

The effect of exogenous application; seed priming or foliar spraying of salicylic acid (SA) on Yecora Rojo and Paragon wheat cv. under NaCl-salinity. Gas exchange parameters, growth parameters, yield and yield components were reduced in both cultivars under salinity stress with foliar spray and soaking seeds. Exogenous application of SA through foliar spraying or seed soaking showed a slight in...

Salinization of soil is primarily caused by capillary rise from saline shallow groundwater orapplication of saline irrigation water. In this investigation, the transient state analytical modelwas modified to predict water uptake from saline shallow groundwater, actual cropevapotranspiration, soil water content, dry matter, seed yield and soil salinity under differentsaline groundwater depths, i...
