چکیده

Considering global warming as a major constraint of yield and quality, the present study accessed impact terminal heat stress on wheat stability grain Fe Zn content in wheat. Twenty-three genotypes CGIAR Research Program (CRP) two check varieties, PBW343 HD2967 were evaluated for under conditions at stage. Stability measures indicated CRP7, CRP8, CRP33, CRP46, CRP48 to be most stable genotypes. Grain iron (Fe) zinc (Zn) showed high degree variation. Under normal sown varied from 20.47 ppm (HD2967) 76.07 (CRP7) while 25.17 65.6 (CRP48). stress, variation was observed 10.17 (PBW343) 43.93 (CRP54) whereas ranged 20.33 (CRP30) 55.13 The overall average reduced by 31.98 % 5.91% indicating highly vulnerable than content.

Effect of salinity on wheat (Triticum aestivum L.) grain yield, yield components and ion uptake

Crops growing in salt-affected soils may suffer from physiological drought stress, ion toxicity, and mineral deficiency. A pot study was conducted in 2004-2005 in the Aghala area (northern Iran) to study the effect of different salinity levels, i.e. ECe= 3 (control), 8, 12 and 16 dS m-1 on wheat grain, yield components and leaf ion uptake of four Iranian wheat genotypes, i.e. Kouhdasht, Atrak, ...
