Abstract

In order to study effect of seed priming on seedling emergence and vigour of wheat cultivar ,experiment was conducted in laboratory seed and field ,in seed andamp; plant certification and registration Institute in 2009. Experimental design was a factorial based on completely randomized designs with four replication. Two cultivars (Azar-2,Sardare-101)andtimes; four priming media and control (un soaked) were used in this experiment. Seeds were primed for 12 hour and 20 ċ in four priming media , PEG 10%, KCl 2%, KH2PO4 0/5%, distilled water and control. In pot experiment seedling emergence percent, seedling leugth, primary root and shoot leuth, and sedling dry weight, primary root and shoot dry weight and mean seedling emergence rate and time and in tield experimcut seedling emergence percent and mean rate and time detemined. Result vevealed . The interaction among seed priming media andtimes;cultivar showed the significant effects on stem length , root dry weight ,stem dry weight and total dry weight (andalpha;= %1), seedling length and Mean Emergence Rate (andalpha;=5%). All of the priming media caused that seeds emergence rapidly in compare with control. In compare among seed priming, Maximum root dry weight, stem dry weight and total dry weight was obtained for seeds osmoprimed with KCl 2%.The most percent emergence, mean emergence rate and seedling length was obtained for seeds osmoprimed with PEG 10%.In field condition hydro priming improved the rate of germination . In compare among seed priming, the most percent emergence in field was obtained in PEG 10%.The interaction among seed priming , seed priming media andtimes;cultivar showed the significant effects on percent emergence. The most was observed in sardari-101andtimes; KCl 2% and PEG 10%andtimes;Azar-2.
