Abstract

Four sources of 23-year-old black spruce (Picea mariana (Mill.) B.S.P.) from a provenance test at the Petawawa National Forestry Institute (46° N, 77°30¢ W) were assessed for height growth, shoot phenology and seasonal gas exchange. The provenances were designated 7000 (Yukon, 63°34¢ N, 135°55¢ W), 6979 (Alberta 52°22¢ N, 115°15¢ W), 6908 (Ontario, 48°59¢ N, 80°38¢ W) and 6901 (Ontario, 45°10¢ N, 77°10¢ W).
