Abstract

The effects of priming on the seeds of Beta vulgaris L. with PbSO4 and FeSO4 under NaCl stress was observed at germination and seedling growth. For this purpose all seeds were primed with 100 and 200 ppm solution of PbSO4 and FeSO4 and then treated with various applications i.e. 60mM, 90mM and 120mM of NaCl solution. The results demonstrated that high level of salinity decreased the germination percentage and all other parameters of the growth of seedlings including shoot, root length, fresh & dry weight.  It was recorded that seeds primed with PbSO4 showed lowest germination speed with mean value of (481.42 & 499.77) and also the lowest germination percentage (56 % & 50%) at two concentrations level (100 &200 ppm) respectively. FeSO4 at 200ppm showed highest shoot length (8.18cm) and root length (4.2cm) than that of 100 & 200 ppm of PbSO4 and 100ppm FeSO4. Results concluded that priming can reduce the effects of salinity.
