Effect of seed priming on the germination behavior of wheat

ABSTRACT: In order to evaluate the effect of different seed priming techniques on germination and morphological characters of wheat an experiment was conducted in 2010 in a factorial experiment based on the complete randomized block design with 2 factors in iran. Seeds were primed for 15, 30 and 45 hours in seven priming media (PEG 5%, PEG 10%, KNO3 1%, KNO3 2%, KCl 4%, KCl2% and distilled water as control). Maximum seed germination percentage was observed when seed primed by PEG 10% for 45 h. The most stem and radical length were obtained for seeds with KCl 2% and KCl 4% for 45 h. Rate of germination was improved when the seed soaked water and PEG 10%. There was interaction between seed priming media × priming duration showed the beneficial effects on germination percentage, stem length
