Stemmeteknik

Stemmeteknik is a term used in Swedish-language horticultural and botanical literature to describe the set of techniques that involve stems—the above-ground axis of vascular plants—and how they are managed, propagated, and studied. The concept covers both practical cultivation methods and experimental approaches that focus on stem tissue and architecture.

Common stem-based techniques include propagation from stem material, such as stem cuttings and layering, as well as grafting stem portions onto different rootstocks. Training and pruning of stems aim to shape plant form, improve light exposure, support fruiting, and maintain health in crops and ornamentals. In propagation, plant growth regulators, notably auxins, are used to enhance rooting and callus formation on stem explants, and micropropagation relies on stem tissue grown in culture under sterile conditions. Stem performance is also assessed in terms of growth rate, resistance to bending or breaking, and responses to environmental stress.

Education and practice in stemmeteknik are found in horticultural programs, nurseries, and research settings. Practitioners combine knowledge from plant physiology, genetics, and pathology to select compatible rootstock–scion combinations, optimize pruning schedules, and safeguard stem health. The field overlaps with broader plant propagation, crop management, and experimental botany.

Notes: The exact usage of the term may vary, and some writers prefer more specific terms such as grafting, pruning, layering, or micropropagation when referring to particular techniques.
