Abstract

To investigate the influence of shading materials with growing stages in Panax Ginseng C. A. Meyer, the diurnal change of photosynthesis, stomatal conductance, transpiration and its any correlation were measured. The net photosynthetic rate and stomatal conductance of ginseng were higher in the morning than in the broad day. The net photosynthetic rate was increased as the PAR (Photosynthetically Action Radiation) was increased and it was reached the maximum at the $200\;{\mu}mol/m^2/s$ of PAR in overall leaves. Transpiration rate was increased in the afternoon compared to in the morning. The transpiration rate was higher in rain shelter shading plate than in polyethylene net. A linear equation was obtained between net photosynthetic rate and stomatal conductance in the morning. SPAD was higher in rain shelter shading plate than in polyethylene net through all growth stages. It may result from the decrease of growth progress. From investigating photosynthetic characteristics, we concluded that shading plate of rain shelter was more an efficient material to ginseng growth.

인삼의 차광재료가 생육시기별 광합성, 증산작용 및 기공전도도의 일변화에 미치는 영향을 구명하고자 다음과 같이 실시하였다. 삼집내 자연광과 인공광선을 이용하여 광합성, 증산, 기공전도도 및 엽록소를 측정하여 다음과 같은 결과를 얻었다. 생육시기별 광합성속도의 일변화는 오전에 증가하다가 오후로 갈수록 감소하는 경향을 보였으며 차광망에 비하여 차광판에서 높았다. 증산작용은 광합성작용과 반대로 오후로 갈수록 증가하는 경향을 보였고 기공전도도는 오후로 갈수록 감소하는 경향을 보였다. 광합성속도와 기공전도도와의 관계는 오전에서 l차직선회귀식으로 정의 상관관계가 인정되었으나, 오후에서의 양자간의 관계는 인정되지 않았다. 일복재료별 엽록소의 변화는 모든 처리구에서 생육이 진전됨에 따라 SPAD값이 감소하는 경향이었으며, 차광망에 비하여 차광판의 SPAD값이 전 생육기간에 높은 경향이었다.
