Seeds of muskmelon (Cucumis melo) cultivars viz. Pb. Hybrid and Pb. Sunehri were osmoconditioned with Polyethylene glycol j(PEG) and KNO, solutions to enhance their performance at low temperature. Osmoconditioning both with PEG 6000 and KNO3 increased per cent germination, speed of germination, vigour in terms of dry weight and length of the seedlings and root/shoot ratios. KNO3 priming recorded more pronounced effect in all the above mentioned parameters. Other vigour parameters such as electrical conductance of seed leachates was decreased with osmoconditioning while dehydrogenase activity was enhanced. Osmoconditioning resulted in increased activity of amylases.

PL

Nasiona dwóch odmian melona (Cucumis melo) byty osmokondycjonowane glikolem polietylenowym ( PEG ) i KNO3 dla poprawienia ich reakcji na niskie temperatury. Użycie obu wymienionych preparatów zwiększyło procent i szybkość kiełkowania, wigor roślin określany ich suchą masą i wielkością siewek oraz stosunek korzeń/pęd. KNO3 miał bardziej wyraźny wpływ na wszystkie wymienione cechy. Inne parametry wigoru, np. przewodnictwo elektryczne cieczy otrzymanej w wyniku przemywania nasion ulegało obniżeniu pod wpływem osmokondycjonowanía, podczas gdy aktywność dehydrogenazy i amylaz była zwiększona.
