Lagerförökning

Lagerförökning refers to the process of vegetative reproduction in plants that involves the formation of roots or shoots that can grow into new plants. This method is commonly used by several types of plants, including conifers and other types of gymnosperms, as well as certain species of ferns and flowering plants.

In lagerförökning, a single parent plant produces one or more genetically identical offspring through a process known as stolon formation or runner production. A stolon is an stem or runner that produces roots at its nodes, allowing it to grow and produce new shoots. This process can occur above ground or underground, where the stolons may produce roots and new shoots in the rhizome.

The new plants that grow from the stolons are genetically identical to the parent plant, as they develop from the same genetic material. This process allows for rapid and efficient propagation of plants that produce stolons. Lagerförökning is also known for its ability to produce plants with similar traits and characteristics as the parent plant, making it a useful technique in agriculture and horticulture.

Several plant species that use lagerförökning to reproduce include blackberries, raspberries, and strawberries in the genus Fragaria. Sedges (Carex spp.) and some species of quaking grass (Briza spp.) also use this method of reproduction. The benefits of lagerförökning include its efficiency, rapidity, and the potential for genetic similarity between parent and offspring. However, it may also pose risks of inbreeding and the limitation of genetic variation if not managed properly.
