Abstract

Green peppers (Capsicum annuum L. cv, Soonjung) were grown under different combinations of $CO_2$ concentration and temperature levels and examined on the effect of elevated $CO_2$ and temeprature on plant growth, carbon and nitrogen concentrations. Plant height was stimulated by elevated $CO_2$ levels at 20.3 and 22.6$^{\circ}C$. Leaf area and fresh weight were remarkedly increased by high $CO_2$ concentration at 22.6$^{\circ}C$. Dry weights of leaf, stem, root, and whole plant were increased as temperature increased at 611 ppm $CO_2$, but those values decreased at 22.6$^{\circ}C$ in 397 ppm $CO_2$ concentration. Elevated $CO_2$ increased plant growth by 1.5 times at 20.5$^{\circ}C$ and 22.6$^{\circ}C$. C/N ratio increased with increasing temperature under elevated $CO_2$ levels.

고추(Capsicum annuum L. cv. Soonjung)의 plug tray육묘시 $CO_2$와 온도처리가 우량묘생산에 미치는 효과를 조사 분석하였다. 초장은 611 ppm의 $CO_2$를 처리하였을 경우에 20.3$^{\circ}C$와 22.6$^{\circ}C$의 고온하에서 촉진되었으나, 15.6$^{\circ}C$의 저온하에서는 촉진효과가 없었다. 엽면적과 생체중은 22.6$^{\circ}C$의 고온에서 고농도의 $CO_2$를 처리하였을 경우에 현저히 증가하였다. 잎, 줄기, 뿌리 및 총건물중은 611 ppm의 $CO_2$를 처리하였을 경우에 온도가 상승할수록 증가하였으나, 397ppm의 $CO_2$농도에서는 22.6$^{\circ}C$의 고온에서 건물중이 감소하였다. 611 ppm의 $CO_2$처리에 의한 건물중의 증가는 20.3$^{\circ}C$ 이상의 고온과 고농도의 $CO_2$에서 약 1.5배 증가하였다. C/N율은 611 ppm의 $CO_2$ 처리가 397 ppm의 $CO_2$ 농도에서보다 높고, 온도의 상승과 함께 증가하였다.
