Current knowledge on root growth mineral nutrition and response to high temperature co2 enrichment and climate change frosts water stress and flooding are also covered. The review ends with an overview of stand establishment and field performance of planted seedlings. The authors highlight the need for research on the long-term effects of multiple stresses such as climate change and air pollution on the black spruce ecosystem.
