What is the definition of a corm?

The definition of a corm is an underground, enlarged, solid stem that serves as a storage organ filled with nutrients. Corms are significant in the life cycle of certain plants as they store energy and carbohydrates, which the plant can utilize during growth periods, particularly in adverse conditions. This storage is crucial for the plant's survival and allows it to produce new shoots and roots when conditions improve.

The structure of a corm is distinct from other storage organs like tubers or bulbs, as it is primarily a stem rather than a root or a bulb with fleshy scales. Recognizing that the corm develops below ground and can contribute to both vegetative reproduction and energy storage is essential in understanding plant propagation and ecology.

This emphasizes the function of corms as energy reservoirs, which aids in plant survival through cycles of dormancy and growth. Understanding the role of corms is vital for agricultural practices and managing aquatic plant communities, particularly in controlling invasive species or promoting desired flora.
