Effect of hydration treatments on seed parameters of different lettuce (Lactuca sativa L.) seed lots
Original language description
The influence of hydration treatments on seed parameters of lettuce seed lots with different initial quality was investigated. Nine seed lots were treated by prehydration (duration 3, 6, 12 and 24 hours) and by osmopriming in polyethyleneglycol 6000 solution (duration 24, 72 and 144 hours) with osmotic potential -1.5 MPa. The result of hydration treatment depends on seed lot attributes. The germination percentage is not a sufficient criterion for determination of seed convenience for hydration treatment. Possible complementary parameter can be mean time of germination (MTG) with high correlation between non-treated and treated seed lots. Effect of hydration depends also on hydration method and its duration. The osmopriming is more suitable method for lettuce seed than prehydration. Generally shorter duration of hydration (till 6 hours at prehydration and till 72 hours at priming) proved more effective on lettuce seed lots parameters after treatment.
