The effect of Osmopriming and Hydropriming on the different index of germination& early growth of wheat under salty stress

ABSTRACT:In order to investigation into the effects of wheat seedʹs Osopriming and Hydropriming in the plant extract and the seed soaking time on the germination under sality stress, an examination was performed in two of stage (priming procedures and planted in the pot) in factorial with 3 factors in a randomized block design in Mohagegh Ardabili universityʹs Agricultural laboratory in 2009 which including factors: 1) types of Osmotic solution (3% Nacl Solution (S1) , 5% Mannitol (S2), 25% sugar beet extract (S3) and distilled water (S4))2): Duration of priming (4,8,10) Hours, 3) salinity with EC=(0(SS0) , 3 (SS3), and 6(SS6)) millimouse/ Square Centimeter with three replications under controlled conditions (the same), respectively. The results from statistical analysis showed the simple effect of priming for all the characteristics under study, except of shoot dry weight and simple effect of salinity for all the characteristics under study in the experiment at 1% level was significantly simple effect of seed soaking time (4 hours) only on hypocotyle length was significantly. Interaction of salinity on seed priming for root dry weight, longest root on the 5% level showed a statistical significant difference. Also shoot dry weight has a positive and significant correlation with the first and second leaf length, root number and root longest at the %1 level.
