Effectiveness of winter temperatures for satisfying chilling requirements for reproductive budburst of red alder (Alnus rubra).

ABSTRACT:

Background

Experiencing an adequate amount of cold temperatures over winter is necessary for many temperate tree species to break dormancy and flower in spring. Thus, changes in winter and spring temperatures associated with climate change may influence when trees break dormancy and flower in the future. There have been several experimental studies that have quantified the effectiveness of cold temperatures for chilling requirements for vegetative budburst of temperate trees; however, there are few experimental studies addressing the chilling requirements for reproductive budburst of trees, as it is difficult to place reproductively mature trees in temperature-controlled environments.

Methods

To identify how changing temperatures associated with climate change may impact rep
