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 .
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 ...
Soaking the seeds in cold water for 6–12 hours before placing them in cold stratification can cut down on the amount of time needed for stratification, as the seed needs to absorb some moisture to enable the chemical changes that take place. [citation needed]
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 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.
Water chestnut may refer to either of two plants, both used in Chinese cuisine: Eleocharis dulcis , or Chinese water chestnut, is eaten for its crisp corm Water caltrop , Trapa natans , is eaten for its starchy seed
The Tahitian chestnut is a medium-sized, evergreen tropical tree. It may grow to 30 m in height, though 20 m is more usual, with a crown diameter of 4–6 m. Mature tree trunks have a typical diameter at breast height of 300 mm, although some grow to a diameter of 900 mm. The trunks are distinctively buttressed at the base and fluted.
Dioon edule, the chestnut dioon, is a cycad native to Mexico, also known as palma de la virgen. Cycads are among the oldest seed plants and even pre-date the dinosaurs. [3] It belongs to the Zamiaceae plant family within the order Cycadales. The genus name "Dioon" means "two-egged", referring to the two ovules (see photo below).
