Genetics Of Quaking Aspen

Excerpt from Genetics of Quaking Aspen Edmonton, Moss (1960) found that the average date of flowering for quaking aspen has been April 25 for the period 1928-1960, and occurred only after 6 days of air temperatures of 12 C or more. An increasing heat requirement for flowering in more severe cli mates could be an important survival trait, but provenance studies are needed to determine if such is the case.
