These propagate corm-forming plants. A number of species replace corms every year by growing a new corm. This process starts after the shoot develops fully expanded leaves. The new corm forms at the shoot base just above the old corm. As the new corm grows, short stolons appear that end with the newly growing small cormels. As the plants grow ...
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
Corms are solid enlarged underground stems that store nutrients in their fleshy and solid stem tissue and are surrounded by papery leaves. Corms differ from bulbs in that their centers consists of solid tissue while bulbs consist of layered leaves. [24] Examples of plants that use corms are gladiolus and taro.
This is particularly common in species that develop underground storage organs, such as bulbs, corms and tubers. Tulips and lilies are examples of plants that display offset characteristics by forming cormlets around the original mother corm. In the UK, the term 'bulbils' is used for lilies.
English: The leftmost image shows the entire corm in its tunic.The second shows the tunic partly peeled off to show the leaf bases comprising the tunic and the lines where the sessile leaves sprouted from the corm cortex, showing the nodes that demonstrate that the corm body is a stem with nodes and buds.
Eleocharis dulcis, the Chinese water chestnut or water chestnut, is a grass-like sedge native to Asia, tropical Africa, and Oceania.It is grown in many countries for its edible corms, but if eaten uncooked, the surface of the plants may transmit fasciolopsiasis.
It is the most widely cultivated species of several plants in the family Araceae that are used as vegetables for their corms, leaves, stems and petioles. Taro corms are a food staple in African, Oceanic, East Asian, Southeast Asian and South Asian cultures (similar to yams). Taro is believed to be one of the earliest cultivated plants.
Typically after the formation of the new plant the stolon dies away [6] in a year or two, while rhizomes persist normally for many years or for the life of the plant, adding more length each year to the ends with active growth. The horizontal growth of stolons results from the interplay of different hormones produced at the growing point and ...
