CO 2 Enriched Air Increased Growth of Conifer Seedlings

The dry weight of 3-week-old seedlings of white spruce, Norway spruce, jack pine and Scots pine was 30–80% greater than the control when grown in atmospheres enriched 3- to 5-fold with carbondioxide. Seedlings also responded positively to a difference in light intensity. CO 2 enriched atmospheres mi...

Zusammenfassung:The dry weight of 3-week-old seedlings of white spruce, Norway spruce, jack pine and Scots pine was 30–80% greater than the control when grown in atmospheres enriched 3- to 5-fold with carbondioxide. Seedlings also responded positively to a difference in light intensity. CO 2 enriched atmospheres might profitably be used for the short term propagation of tree seedlings grown in greenhouses.
