Slaney, M. 2006. Impact of elevated temperature and [CO2] on spring phenology and photosynthetic recovery of boreal Norway spruce. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-7052-8 In recent decades, several methods have been devised to study the effects of elevated atmospheric CO2 concentration, [CO2], and temperature on tree and plant physiological responses. This has resulted in the development of a range of systems to expose tree species to elevated [CO2] and/or temperature and it has become obvious that there is a strong need for multifactor experiments, which at the tree and stand level can become both a technical and financial challenge. Most available information on the effects of elevated [CO2] and increased temperature on trees comes from single factor experiments on seedlings or saplings and the results from these studies may not be directly applicable to mature trees or forest stands. This thesis is based on data gathered from mature Norway spruce trees growing in whole-tree chambers in northern Sweden, where both temperature and [CO2] were controlled according to climate conditions predicted to prevail in the year 2100.
