plantling

A plantling is an early developmental stage in the life cycle of certain plants, particularly those that exhibit a form of vegetative reproduction known as apomixis or those that grow from specialized structures like bulbs, tubers, or corms. Unlike seeds, which develop from fertilization, plantlings arise asexually, meaning they are genetically identical to the parent plant. This process allows for rapid propagation and the maintenance of desirable traits without genetic variation.

Plantlings are commonly found in plants such as some species of lilies, irises, and certain types of orchids, where small bulblets or offsets form along the parent plant’s rhizomes or stems. These structures detach naturally or can be carefully separated by gardeners to encourage new growth. The term is also sometimes used more broadly to describe young plants that have recently sprouted from seeds or cuttings, though this usage is less precise.

In horticulture, plantlings are valued for their ability to produce clones of parent plants with consistent characteristics, such as disease resistance or flowering patterns. They are often used in commercial propagation to maintain uniformity in cultivated varieties. However, the lack of genetic diversity in asexually produced plantlings can make them more vulnerable to pests and diseases that affect their parent plants.

While the term "plantling" is not widely standardized, it is occasionally encountered in botanical literature or gardening discussions. Its usage may vary depending on regional terminology or specific plant families. Gardeners and plant breeders may refer to them as offsets, bulblets, or simply "new growth," depending on the context.
