This study was conducted to analyze the seedling quality of korean melon and the growth after transplanting of korean melon nursed under the LED sources. LED sources were RB7 (Red:Blue=14:2), RB3 (Red:Blue=12:4) and Blue(B=16). Photosynthetic photon flux density(PPFD) was 50, 100 and 200μmol·m-²ㆍs-¹. The lighting treatment was started after graft-taken and was applied for 20 days at 4 hours(05:30 and 07:30, 17:30 and 19:30) per day. Plant height and stem diameter of scion were longer and thicker under a high ratio of blue light condition. Dry matter ratio and compactness were highest in RB3 compared to the other LED sources treatments. CO2 exchange rate increased 5.44μmolCO2ㆍm-²ㆍs-¹ under RB7 200μmolㆍm-²ㆍs-¹ and dropped to negative values under control. PPFD 200μmolㆍm-²ㆍs-¹ of RB3 resulted in the longest plant height by 132.3cm and flowering ratio also was the highest by 75%.
