Seedlings of Cinnamomum camphora were exposed to both ambient (350±20 ? L L??) and enriched 700±30 ? L L?? levels of CO? in combination with four nitrogen concentrations (112、224、448 and 896 ppm) for 12 weeks. Seedling growth in enriched CO? were increas

樟樹苗木在常態與提高二氧化碳濃度(350, 700 ? L L??)及不同氮肥(112, 224, 448, 896 ppm)施用下,經12週之培育後,顯示生長在常態二氧化碳濃度下之樟樹苗,以施用如Hoagland solution之224 ppm氮肥者最適合,太低或太高皆不宜。至於生長在提高二氧化碳濃度者,則顯現出隨施用濃度的增加而增加,以896 ppm有顯著的促進效果。以結果顯示生長在提高二氧化碳濃度下,供應超過Hoagland solution之標準氮肥濃度,非但不會抑制生長,反具促進效果。生長於7
