kärnfrö

Kärnfrö, also known as core or core seed, is the central part of a seed that contains the embryo of the plant. It is surrounded by the endosperm, a food storage tissue that provides nutrition to the developing plant.

The kärnfrö is formed during the development of the seed and is composed of the cotyledon, radicle, and plumule, which are the primary tissues of the plant embryo. The cotyledon is the leafy structure that provides the plant with nutrients, the radicle is the primary root, and the plumule is the shoot apical meristem.

In some plant species, the kärnfrö is very small or even absent, while in others it can be relatively large. In legumes, for example, the cotyledon can be quite prominent and fused into a single unit with the kärnfrö.

The kärnfrö plays a crucial role in the germination of the plant, providing the necessary nutrients and structures for the development of the seedling. It is also an important characteristic used in plant breeding and taxonomy, as different plant species and varieties can have distinct kärnfrö structures.

The study of kärnfrö and its development is an important area of research in plant biology and genetics. Understanding the development and structure of the kärnfrö can provide insights into the mechanisms of seedling establishment and plant development, which can be useful in breeding and agricultural applications.
