The effects of seed priming on seedling development of muskmelon (Cucumis melo L.) under laboratory and greenhouse conditions were studied. Seeds of `Top Net, SR' muskmelon were primed for 6 days in darkness at 77 °F (25 °C) in KNO3 (0.35 m) aerated solution. After germination in petri dishes at 77 °F, primed and nonprimed seeds were transferred to either paper towels (laboratory study) or trays, which were placed in greenhouse conditions. Leaf area and fresh and dry mass of roots and shoots were measured at 15 and 30 days. In germination under laboratory conditions, primed seeds germinated ≈16 and 60 hours earlier than nonprimed seeds at 77 °F and 63 °F (17 °C), respectively. Priming caused no beneficial effect on shoot and root development either in laboratory conditions or during transplant production in the greenhouse.
