Evaluation of salinity stress on emergence and yield of priming wheat (Triticum aestivum L.)
Abstract:   (16912 Views)

Soil salinity is considerable problem adversely affecting physiological and metabolic processes, finally diminishing growth and yield. Seed priming treatments can effective induce salt tolerance and enhance stand establishment in non-saline and saline areas. This experiment was conducted to evaluate the effects of different seed priming with 50 mM NaCl, 0.5% KH2PO4, 0.3% ZnSO4, 50 mM CaSO4, 50 ppm gibberellic acid (GA3), and H2O for 12 h and 50 ppm ascorbic acid for 16 h on emergence and yield of wheat under low (4.5 dS/m) and high saline (9 dS/m) conditions. All seed priming treatments hastened germination under saline and non-saline conditions as compared to those of non-primed seeds. The highest seed emergence percent in 4.5 (92%) and 9 dS/m (87%) salinity condition was observed in GA3 treatment. Also the highest emergence rate was for GA3 treatment in both of salinity levels. In conclusion, the results showed that despite some positive effects of seed priming on emergence and stand establishment and improve the salt stress tolerance of wheat in this stage but the grain yield was not impressed and there were no differences between priming treatments and control at normal and saline soil conditions.
