seitenzweige

Seitenzweige are lateral branches that grow from the main stem or trunk of a plant, tree, or shrub. They form part of the crown architecture and contribute to the plant’s photosynthetic capacity, structural support, and, in many species, to reproduction by bearing leaves, flowers, or fruit.

They originate from latent or axillary buds located at nodes along the main axis. In many woody plants, growth is controlled by apical dominance, a hormonal effect primarily driven by auxin produced in the apical bud, which suppresses the growth of competing lateral buds. When the terminal shoot is removed or its growth is otherwise reduced, latent buds can develop into Seitenzweige. Environmental factors such as light, temperature, and nutrient availability also influence their development.

The pattern and density of Seitenzweige affect canopy shape, wind resistance, and wood quality. In forestry and horticulture, managing Seitenzweige through pruning and training helps optimize light distribution, air circulation, and fruit production. Common practices include selective removal of inward- or overlapping shoots, shortening frequently growing shoots to control vigor, and encouraging desired branch angles.

In botany and tree physiology, Seitenzweige are distinguished from primary branches by their origin and typically undergo secondary growth via the vascular cambium, contributing to the plant’s overall girth. The term is used across many woody species, though exact growth habits vary.
