|Title:||Allelopathic potential of 'Hyparrhenia hirta' (L.) Stapf. on native grass||Contributor(s):||Chejara, Vinod Kumar (author); Kristiansen, Paul (author) ; Whalley, Ralph D (author) ; Nadolny, Christopher (author); Sindel, Brian Mark (author)||Publication Date:||2007||Handle Link:||https://hdl.handle.net/1959.11/11416||Abstract:||'Hyparrhenia hirta' (L.) Stapf. (Coolatai grass, Tambookie grass) is an invasive, perennial grass from Africa and the Middle East that has infested large areas of northern New South Wales, Australia, and also occurs in other Australian states. Invasive perennial grasses can be aggressive colonisers and a major threat to the biodiversity of native ecosystems. There are many possible mechanisms by which invasive plants may affect native species such as resource competition, habitat modification and altered ecosystem processes. The present investigation studied the allelopathic potential of 'H. hirta' on germination and seedling vigour of the Australian native grass species, 'Bothriochloa macra' (red grass) and 'Dichanthium sericeum' (Queensland blue grass). In an incubator experiment, aqueous extracts derived from root and shoot of 'H. hirta' were applied to the target species. The full strength extracts (1:10 w/v plant material in water) of H. hirta were used to make the following dilutions: control (deionized water only), 0.1, 1, 10,50,75, and 100 % (v/v).||Publication Type:||Conference Publication||Conference Name:||9th International Conference on the Ecology and Management of Alien Plant Invasions (EMAPi9), Perth, Australia, 17th - 21st September, 2007||Conference Details:||9th International Conference on the Ecology and Management of Alien Plant Invasions (EMAPi9), Perth, Australia, 17th - 21st September, 2007||Source of Publication:||EMAPi9: 9th International Conference on the Ecology and Management of Alien Plant Invasions Program and Abstract Book, p. 212-212||Publisher:||Congress West||Place of Publication:||Perth, Australia||Field of Research (FOR):||060208 Terrestrial Ecology||HERDC Category Description:||E3 Extract of Scholarly Conference Publication||Statistics to Oct 2018:||Visitors: 345
