ABSTRACT
The purpose of this study was to examine the reaction in variable light environments on shade tolerant species, Chloranthus glaber. We raised Chloranthus glaber seedlings under four light conditions: PPFD 400, 250, 100μmol m-2s-1 and full sunlight (PPFD 1600μmol m-2s-1). Using 2 years old seedlings, chlorophyll content, photosynthetic rate, stomata conductance and intercellular CO2 concentration were investigated. Shaded seedlings had higher chlorophyll content, photosynthetic rates, and stomatal conductance, but not higher intercellular CO2 concentration than those in the full sun treatment. This result suggested that growth and physiology of Chloranthus glaber adapted to low light intensity.

적요

내음성이 강한 죽절초 유묘를 대상으로 죽절초의 생육환경 변화에 따른 반응을 보기 위하여 서로 다른 광조건의 비음처리 I, II, III 그리고 자연조건(fullsunlight)을 구분하여 각 처리구별 죽절초의 생리적 반응을 비교하였다. 생리적 반응의 비교를 위한 측정요소로 엽록소 함량, 광합성율, 기공전도도, 엽육 세포내 CO2농도를 조사하였다. 비음처리구간간의 차이는 크게 나타나지 않았으나, 자연조건과 비음 처리구와의 차이는 크게 나타났다. 자연조건(full sunlight)일 때, 죽절초는 비음 처리구에 비하여 낮은 엽록소 함량과 광합성율, 기공전도도를 나타냈으며, 엽육 세포내 CO2농도와 수분이용효율이 높게 나타났다. 이것은 죽절초의 광합성기구에 광저해 현상이 일어나 광반응 기구에 피해를 준것으로 보여지며, 적은 양의 빛을 효율적으로 이용하기 위해 순화된 죽절초는 높은 광조건하에서 잘 적응하지 못하고, 높은 광이 스트레스로 작용함을 알 수 있다.
