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 .
In horticulture, stratification is a process of treating seeds to simulate natural conditions that the seeds must experience before germination can occur. Many seed species have an embryonic dormancy phase and generally will not sprout until this dormancy is broken.
Stratification in water is the formation in a body of water of relatively distinct and stable layers by density. It occurs in all water bodies where there is stable density variation with depth. Stratification is a barrier to the vertical mixing of water, which affects the exchange of heat, carbon, oxygen and nutrients. [1]
The plants of a layer, especially with regard to their way of life and correspondingly similar root distribution interact closely and compete strongly for space, light, water and nutrients. The stratification of a plant community is the result of long selection and adaptation processes. Through the formation of different layers a given habitat ...
The plant spreads by the rosettes and fruits detaching from the stem and floating to another area on currents or by fruits clinging to objects, and animals. The unrelated Eleocharis dulcis is also called a water chestnut. [2] It is an aquatic plant, a sedge, whose round, crisp-fleshed corms are common in Chinese food.
Layering is a vegetative propagation technique where the stem or branch of a plant is manipulated to promote root development while still attached to the parent plant. Once roots are established, the new plant can be detached from the parent and planted. Layering is utilized by horticulturists to propagate desirable plants.
Flower differentiation is a plant process by which the shoot apical meristem changes its anatomy to generate a flower or inflorescence in lieu of other structures. Anatomical changes begin at the edge of the meristem, generating first the outer whorls of the flower - the calyx and the corolla, and later the inner whorls of the flower, the androecium and gynoecium.
Leaf and flower detail of a Chinese chestnut at New York Botanical Garden. It is a deciduous tree growing to 20 metres (66 ft) tall with a broad crown. The leaves are alternate, simple, 10–22 centimetres (4– 8 + 1 ⁄ 2 in) long and 4.5–8 cm (1 + 3 ⁄ 4 – 3 + 1 ⁄ 4 in) broad, with a toothed margin.
