Abstract

The effects of pregerminative hydrationdehydration treatments over germination of four varieties of fresh papaya seeds were determined with low initial germinative power and high viability. Six pregerminative hydration-dehydration treatments with different levels of partial hydration in water or KNO3 were applied. Test treatments were done under three alternate temperature conditions of the substratum (25-30, 25-35 and 25-40°C). In the 25-30°C thermoperiod, the best results were achieved to accelerate and increase germination in all the varieties except Maradol Roja-1, when seeds were hydrated in KNO3 for 30 minutes and with a cycle of hydration-dehydration in water or KNO3. In 25-35°C, the previous treatments have similar results on the beginning of radicule emergency in Nika y Maradol Rojo-90 varieties; however, germination was not obtained in the rest. None of the varieties germinated in the 25-40°C thermoperiod, even after seed treatments.
