초록

야파의 경비를 절감시키고 실제 농가에서 활용하기 위하여 시중에서 판매되고 있는 광질 조절 전구인 적색등, 청색등 및 삼색등을 구입하여 암기의 중간에 10분 동안 야파한 후 식물체의 생육에 미치는 영향을 조사하였다. 식물체당 잎의 수와 엽면적 및 생체중은 적색등과 삼색등으로 야파한 경우에 가장 많았으며, 다음은 청색등 야파 및 야간의 완전암하에서 가장 적었다. 초장과 줄기의 직경은 적색등, 청색등 및 삼색등으로 조사하였을 경우에 야간의 완전암보다는 신장생장이 현저히 촉진되었다. 줄기의 생체중과 건물중은 삼색 등으로 야파하였을 때에 가장 무거웠으며, 적색등 및 청색등의 순으로 생육이 촉진되었다. 적색등과 삼색등을 이용한 야파는 100일 후에까지 전혀 개화하지 않았으며, 야간의 완전암하에서는 약 85%, 청색광 야파는 31% 개화하였다. 야파후 개화에 소요되는 일수는 야간의 완전암하에서는 야파처리 약 60일 후, 청색광야파는 약 80일이었다. 야파 처리 80일 후에 광합성 율은 적색광으로 야파하였을 때에 가장 높았고 다음은 청색광이었으며, 삼색광하에서 가장 낮았다. 광보상점은 삼색등으로 야파한 경우에는 $20\;{\mu}mol\;m^{-2}{\cdot}s^{-1}$이하로서 낮았는데, 적색광과 청색광하에서는 $20\;{\mu}mol\;m^{-2}{\cdot}s^{-1}$ 이상으로서 약간 높은 경향이었다.

The influences of night break by costly artificial light sources were investigated on the photo-morphogenesis and growth of leafy perilla (Perilla ocymoides L.). The irradiation of red, blue, and three-colored light for night break significantly increased the stem length and stem diameter compared to dark. Three-colored light gave the highest fresh and dry weight of stem, followed by red and blue light. Floral induction was suppressed up to 100 days after the night break, by red and three-colored light, but the plants grown under the dark or treated with blue light showed 85% and 31% flowering rate, respectively. The time needed for floral induction after night break was 60 days in dark and 80 days in blue light. The number of leaf, leaf area, and fresh weight per plant were the highest in red and three-colored light night break, followed by blue light and dark. The photosynthetic rate observed 80 days after night break was the highest in red light, followed by blue and three-colored light. A low light compensation point of $20\;{\mu}mol\;m^{-2}{\cdot}s^{-1}$ was observed in three-colored light, while red and blue light tended to show higher measurements.
