Biennial strobilus production in balsam fir: a review of its morphogenesis and a discussion of its apparent physiological basis
View through CrossRef
A pattern of alternate-year production of strobilus buds and latent lateral buds occurred on bearing shoots in the reproductive zones of the crowns of balsam fir (Abiesbalsamea (L.) Mill.) trees. The timing of all growth events on such shoots and the relative sizes and numbers of organs produced provided a reasonable physiological (source–sink) basis for the biennial production of strobili in this species.
