Шаблон:Short description Шаблон:Other uses Шаблон:Speciesbox
Cortaderia selloana is a species of flowering plant in the Poaceae family.[1] It is referred to by the common name pampas grass,[2] and is native to southern South America, including the Pampas region after which it is named.
Etymology
Cortaderia is derived from the Argentine Spanish name 'cortadera', meaning 'cutter', in reference to its razor sharp leaf margins.[3]
Selloana is named for Friedrich Sellow (1789–1831), a German botanist[3] and naturalistШаблон:Citation needed from Potsdam who worked as a plant collector in Brazil.[3] He studied the flora of South America, especially that of Brazil. The specific epithet selloana was given by Josef August and Julius Hermann Schultes in 1827.Шаблон:Citation needed
Cultivars
Several cultivars are available, of which the following have gained the Royal Horticultural Society's Award of Garden Merit:
- Aureolineata[4]
- Evita[5]
- Monstrosa[6]
- Patagonia[7]
- Pumila[8]
- Silver Feather Notcort[9]
- Sunningdale Silver[10]—grows to a height of Шаблон:Convert and has particularly dense flowering plumes
Population biology
Okada et al., 2007 find C. selloana populations are best distinguished by a Bayesian analysis of genetic features such as microsatellites.[11] Algorithms such as STRUCTURE are suitable for this.[11]
Negative impact
Cortaderia has become invasive in mild-winter areas of North America, especially the southern United States. It has also been banned in Hawaii and New Zealand because of its ability to outgrow and displace native plants. In Europe, it was first introduced in the United Kingdom, later spreading to other countries in the continent like Ireland, Portugal, Spain, France, and Italy.Шаблон:CN It is a common urban invader.[12]
Pampas grass is fast-growing and can form large masses along the roads, cliffs, riverbanks, and open areas that have been disturbed by human activities or natural disturbances. Pampas grass can displace native plants and destroy their habitats, reducing biodiversity.Шаблон:CN
The plant also competes with other native plants by monopolizing resources like shade, sunlight, and ground nutrients. Because of the large surface area, the leaves pose a significant fire hazard if placed near flammable substances.[13]
C. selloana often spreads from landscaping plantings.[11] Okada et al., 2007 find this is the source of the California population.[11]
Control methods
Pampas grass can be controlled through herbicide treatment. To accomplish this, the grass is cut down near the base. Next, a 2% glyphosate chemical solution is combined with a silicone-based surfactant and applied to enhance the penetration potential. This method works best in the fall because there is overall better control compared to other seasons. Another control method is to cut and bag inflorescences to prevent seeds from spreading or pulling seedlings.[14]
Soil disturbance that creates bare ground can promote invasion, so it is essential to minimize disturbance or provide competition to seedlings. In order to control disturbance, applying mulch to exposed bare ground to smother seeds and prevent germination can be done. Also, planting or seeding desirable, non-invasive plants can provide competition to reduce germination and seedling establishment.[14]
C. selloana is considered a promising target for bioherbicide development.[15]
In culture
Author Li Hengrui (Шаблон:Lang), whose work Kite Capriccio (Шаблон:Lang) describes life as a child in 1950s Fengtai County, Anhui mentions the use of the long stem of the Puwei (Шаблон:Linktext, Chinese for Cortaderia selloana) in the construction of kites.[16]
Several media outlets reported in the 2010s that it was planted by some couples who practise swinging in the United Kingdom as a way to indicate to other swingers that they enjoy that lifestyle.[17][18]
The reports caused a plunge in already declining sales, but the odd association has been dismissed by enthusiasts of the plant and gardening experts as "silly".[19][20]
Diseases
O'Donnell et al., 2004 first isolated Шаблон:Vanchor from this species.[21] F. cortaderiae is the cause of Fusarium head blight (FHB) of C. selloana.[21]
