Plant hoppers and scale insects feed on plant sap and may cause subsequent death. [7] Other pests include the nematodes Ditylenchus and Dolichodorus heterocephalus. [9] Fungal species can also attack the Chinese water chestnut. In warmer climates, a rust is caused by Uromyces, [7] and Cylindrosporium eleocharidis causes stem blight. [14]
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 – plant that was intentionally introduced. Common reed – plant introduced in shipment packing material and solid ballast. ... While invasive species have a bad reputation, Lower ...
Some of these species probably contain multiple independently evolving lineages. Because of their difficult nature, it is suggested that many botanists avoid collecting these plants and so many species are under-represented in the botanical record. [citation needed] One of the best known species is the Chinese water chestnut, Eleocharis dulcis ...
However, some plants grow a little too well. “Invasive plants spread aggressively and cause environmental changes, such as the elimination of native plant populations,” says Justine Kandra ...
Rice is the main aquatic plant grown for human food, but smaller areas of watercress and water chestnut are also cultivated. In their native environments, aquatic weeds are part of a balanced ecosystem, and it is mainly introduced species of water plant that become invasive and cause problems by congesting water bodies.
An invasive species might be able to use resources previously unavailable to native species, such as deep water accessed by a long taproot, or to live on previously uninhabited soil types. For example, barbed goatgrass was introduced to California on serpentine soils , which have low water-retention, low nutrient levels, a high magnesium ...
