Abstract

To produce uniform seedlings of tomato and cucumber with inexpensive way, their seedling quality by different light sources was investigated. The raising of seedling was performed by red LED (light emitting diodes), blue LED, red-blue mixed LED or fluorescent light with a fixed PPF(photosynthetic proton flux) level, about $40{\sim}60{\mu}mol{\cdot}m^{-2}{\cdot}sec^{-1}$. In the both tomato and cucumber, the rapid extension of hypocotyledonary axis was observed in Blue LED than fluorescent light, but opposite result was found in Red and mixed LED. During the nursery period of tomato and cucumber, the fresh weight was the highest in Red LED as 74% increasement in tomato and 74% in cucumber. In the case of seedling quality after the tomato nursery, there was no difference in the positions of 1st flower cluster and the number of bearing-flower per flower cluster by each light source. In case of cucumber, until 20th node, the setting ratio of female flower was higher in LED than fluorescent treatment, and also more healthy fruit setting was found in LED. Therefore, we assume that the Red or mixed (Red 2 + Blue 1) LED is more favorable to produce high quality tomato and cucumber seedlings in closed nursery facility.

폐쇄형 육묘시설 내에서 균일한 품질의 플러그묘를 주년으로 생산함에 있어서 LED 광원의 이용 가능성을 검토하기 위하여, 토마토와 오이의 육묘기간 동안에 광원을 달리하여 묘소질을 비교하였다. 적색, 청색, 혼합(적색 2 + 청색 1) LED 및 형광등을 $40{\sim}60{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$로 광도(PPF)를 조사하여 30일간 온도조절이 가능한 폐쇄형 육묘시스템에서 육묘하였다. 토마토와 오이 모두 형광등에 비해 적색 LED와 혼합 LED 처리에서 배축의 신장이 작으면서 튼튼한 묘을 생산할 수 있었다. 토마토와 오이의 생체중은 적색 LED에서 가장 무거웠는데 형광등에 비하여 각각 74% 증가하였다. 토마토의 1화방 착과절위에서는 처리간에 차이가 없었으나, 2화방의 착과절위는 혼합광 처리에서 낮았다. 화방별 착화수는 처리간에 차이가 없었다. 오이의 20절까지의 암꽃 착생률은 적색 LED 처리에서 52%로 가장 높았고, 다음이 혼합광 처리로서 44%였다. 과실 착과수와 수량은 처리간에 차이가 없었다. 이상의 결과로부터 폐쇄형 육묘시설 내에서 토마토와 오이의 묘생산에는 적색 및 적색 2 +청색 1의 혼합 LED가 이용 가능성이 높은 것으로 판단하였다.
