Abstract

This experiment was conducted in order to study the physiological characteristics of Sedum takevimense in different moisture conditions. The photosynthetic rate, water use efficiency and the respiratory rate were determined by using a photable photosynthesis system. According to the results, the best illumination range and moisture range were explicitly selected. The highest photosynthetic rate was at $600{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, and after this value, the trend showed a reduction. When the moisture was 11.31%, the photosynthetic capacity and water use efficiency reached maximum value, but the respiratory rate reached maximum value at 7.91%. According to the measured values, the best illumination range was $600{\sim}1,200{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ and the best moisture range was 7.09~11.31%.

본 연구는 휴대용 광합성측정장치(CIRAS-2, PPS, UK)를 이용하고, 토양 수분조건에 따른 섬기린초의 생리특성을 파악하였다. 섬기린초의 광합성 속도, 식물수분이용효율, 호흡속도 등 측정을 통하여 섬기린초의 생장에 가장 적합한 광도와 토양 수분범위를 명확하게 파악하였다. 광도에 따른 광합성 속도가 증가하였고, $600{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ 경우에서 최고점에 도달한 후 그 이후 감소하는 경향을 나타났다. 토양 수분 조건에 따른 섬기린초의 광합성 속도과 식물수분이용효율은 수분함량 11.31%에서 가장 높은 값을 보였으며, 호흡속도는 수분함량 7.91%에서 가장 높은 값을 나타냈다. 그 결과에 의하면, 섬기린초는 가장 적합한 광도 범위가 $600{\sim}1,200{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$이고, 수분 범위가 7.09~11.31%이다.
