초록
한국특산식물 벌개미취의 재배환경에 따른 생리적 반응과최적 재배조건의 설정을 통해 생산성을 향상하기 위하여 연구를 수행하여 얻어진 결과를 요약하면 다음과 같다. 생육시기별광합성률은 정식 후부터 급격히 증가하였다가 7월 이후 감소하였으며 정식 2년차에서는 생육 후기로 갈수록 저하되는 경향이었고 광보상점은 생육 초기에 높았다가 후기에 감소하였다. 세포내 CO2 농도가 증가할수록 광합성률은 증가하였으나 일정 수준 이상에서는 정체 혹은 감소하는 경향이었고 생육시기별 CO2 보상점은 5월에 가장 낮았다. 차광처리에서 엽록소 함량은 무처리에 비해 높았으며 잎 형태의 유의한 변화가 관찰되었다. 무차광 또는 50% 차광수준에서 광합성률이 높았다. 토양수분 조건에 따라서 잎의 형태적 변화는 거의 없었으나 엽충실도가 변화하였고 -25 kPa 이상의 토양수분조건에서는 광합성률, 순양자수율은 증가하였으며 이에 따라 암호흡속도도 증가하였고 수분이용효율은 감소하였다.
Abstract
This study was conducted to elucidate the photosynthetic response to the environment and establish optimum cultivation conditions for the Korean endemic plant, Aster koraiensis. Photosynthetic characteristics according to growth stage, light, CO2, and soil water potential were investigated. During the first year of transplanting, photosynthetic rates were drastically increased until June, after which they slowly declined, During the second year, photosynthetic rates declined throughout the entire growth period. The highest level of light compensation point was shown the early growth stage. Photosynthetic rates affected by intercellular CO2 concentration were maintained or decreased over the CO2 saturation point. The lowest CO2 compensation point was 16.1 μmol･mol -1 during March. The morphological changes of leaves were observed due to shading with chlorophyll contents increasing. Photosynthetic rates were higher at 0% and 50% shading treatments than at 75%. There were rarely any morphological changes of leaves due to soil moisture, however, changes to leaf compactness were observed. Photosynthetic rate, apparent quantum yield, and respiration rate increased, whereas water use efficiency decreased over -25 kPa of soil moisture. Key words - A-Light curve, A-Ci curve, Shading, Soil water potential
