Abstract:
Carrot was rated as salt sensitive crop, root yield declines by 14% for every unit increase in salinity (EC) beyond threshold of 1.0 dSm⁻¹. In the laboratory studies, Nutri-priming followed by vitamin priming had shown significantly higher performances than unprimed seeds in alleviation of salinity stress. Nutri-priming over unprimed seeds significantly increased Germination percentage, Seedling vigour Index-I, Seedling vigour Index-II, early emergence by 2.4 days and 52% reduction in Seedling electrolyte leakage. In all the treatments, progressive decline in seed quality parameters studied with storage was observed. Different intervals of primed seeds storage suggested that up to 30-days the primed seeds retain viability and vigour, thereafter significant decline at 60- and 90-days storage intervals.
