Corm

The corm is a modified underground shoot that serves as a reservoir of nutrients and an organ of vegetative propagation for the plant. For an agronomist and a passionate gardener, a deep understanding of the biology of this organ is the key to successfully obtaining high-quality planting material. Working correctly with corms allows not only to preserve the unique cultivar traits of ornamental crops but also to effectively manage their growth, development, and flowering processes in open soil or greenhouse forcing conditions.

This compilation gathers materials covering key aspects of working with corm-based plants. Readers will find practical recommendations on cultivation and forcing technologies for popular flower crops, such as gladioli, freesias, tulips, daffodils, and hyacinths. The articles contain information on the main methods of vegetative propagation, principles of agrotechnics, as well as methods for diagnosis and prevention of common diseases, including fusarium rot and physiological deformations. The presented content will help to systematize knowledge about the morphological features of plants and increase the productivity of nurseries or private garden plots.
