Tóm tắt

The processes which generate and maintain genetic variability in natural forest tree populations are reviewed in relation to genetic management of naturally regenerating white pine (Pinus strobus L.) stands. Genetic consequences of inbreeding and silvicultural selection on natural regeneration are discussed, with special reference to old-growth stand management.Ontario's old-growth white pine forests provide a unique opportunity to manage, utilize and conserve pristine gene pools in situ. However, fragmentation of white pine populations in other areas may require ex situ methods to preserve remnants of local genetic variation for future use. Key words: white pine, genetic diversity, inbreeding, mating systems, high-grading, old-growth, genetic resource management, gene conservation
