Abstract

This study was conducted to investigate the effect of early $CO_2$ enrichment during seedling stage on long-term $CO_2$ enrichment after transplanting in the culture of pat-choi (Brassica campesris L), spinach (Spinacia oeracea L.), and leaf lettuce (Lactuca saliva L). During seedling stage, $CO_2$enrichment had significantly higher fresh and dry weight and leaf area of the top parts (above ground) of all three plant species than the control (no $CO_2$ enrichment). About 53%, 70% , and 40% increase in fresh weight of the top parts of pak-choi, spinach, and leaf lettuce were observed, respectively. Also, in seedling stage, dry weights of roots of spinach and leaf lettuce were significantly increased by early $CO_2$ enrichment. Relative fresh weight increment, compared with fresh weight of the control, in the top parts of roll three plants showed the highest values in 10 days after $CO_2$ enrichment treatment. In the long-term $CO_2$ enrichment experiment, early $CO_2$ enrichmented plants had 20% greater leaf area than the control in all three leafy vegetables. Fresh and dry weights of top parts of early $CO_2$-treated plants were also increased from 10 to 20%, as compared with the control plants. However, these increasement rates in the long-term $CO_2$ enrichment were lower than those seedling stage, which had 30-60% increment-rates. After transplanting, photosynthetic rate of each leafy vegetable in the control treatment slowly decreased, but those rates of early $CO_2$ enriched plants rapidly decreased.

본 연구는 엽채류 육묘시 $CO_2$시용이 정식 후 $CO_2$의 장기 시용으로 인한 청경채, 시금치 및 상추의 생육에 미치는 영향을 조사하였다. 육묘시 $CO_2$시용은 청경채, 시금치 및 상추의 지상부 생체중과 건물중 및 엽면적에서 모두 무처리구에 비해 현저히 증가하였는데, 생체중의 경우 처리구에서 각각 50%, 60% 및 30%내외의 증가를 나타내었다 뿌리 건물중은 시금치 및 상추에서 무처리구에 비해 처리구에서 현저히 증가하였다. 무처리구에 대한 지상부 생체중의 상대증가율은 청경채, 시금치 및 상추에서 공히 $CO_2$시용 10일 전후에서 가장 높았다. 정식후 $CO_2$시용 효과를 육묘시 $CO_2$를 시용한 처리구와 시용하지 않은 대조구로 구분하여 비교한 결과, 엽면적은 청경채, 시금치 및 상추에서 모두 처리구가 대조구에 비해 20%내외의 증가를 보였다. 지상부 생체중과 건물중은 처리구에서 3작물 모두 10~20%범위의 증가효과를 보였는데, 이는 육묘기의 30-60%의 증가효과에 비해 크게 둔화된 것으로 나타났다. 잎의 광합성속도는 정식 후 대조구에서 완만하게 감소하는데 비해 CO2를 장기 시용한 처리구에서는 급격히 감소하는 경향을 보였다.
