Abstract
The effect of leaf water content on apparent photosynthesis and respiration of tobacco plants(five varieties) was studied under the condition without the irrigation for 10 days after the plants were sufficiently watered on the first day. The wild race (N. longiflora) among varieties showed highest apparent photosynthesis (AP) and AP had a positive correlation with specific leaf weight. N. longiflora and Andongyeob were different in their AP from the other varieties significantly under the water stress condition. Respiration rate also decreased to be simillar to AP except slight increase at early stage of water deficit. The stomatal resistance and the mesophyll resistance increased in the stressed plants. The water stress resistant character seems to be mainly due to open stomata.
품종간 엽중수분변화에 대한 광합성과 호흡에 미치는 영향을 밝히기 위하여 온실에서 자란 잎담배 5품종의 엽중수분함량을 변화시켜서 광일광합성속도, 호흡속도, 기공저항 및 엽육저항을 각각 조사한 결과를 요약하면 다음과 같다. 1. 품종간 광합성속도는 N. longiflora가 20.7mg
