Bud development and shoot morphology in relation to crown location

Abstract

We investigated crown development in young trees, assessing whether the plasticity in parent shoot and bud growth is mostly related to the position within a crown (upper versus lower branches) or driven by local light conditions. Both larger shoots and buds were associated with increased light availability, whereas leaf-stem allometry was influenced by branch height. The allometry of total bud mass and stem cross-sectional area varied little across the crown, but it changed throughout the summer, driven by bud rather than stem growth. This suggests that bud-stem relationships are regulated locally, at the shoot level, instead of crown-level processes.

Bioengineering and Molecular Biology of Miscanthus

“…In the UK, miscanthus is typically planted in the spring and harvested after rooting for 15 years. New shoots usually appear in mid-spring and grow quickly in the next few months, depending on the genotype, they can reach a height of several meters in mid-summer [13]. Arnoult and Brancourt-Hulmel established that autumn frost causes aging, and as the miscanthus ages, nutrients are transferred from the aboveground organs to the rhizomes [14].…”
