Vegetation management practices, such as defoliation may alter the composition of plant communities and/orthe fungi-forming arbuscular mycorrhiza (AMF). We determined the species identity, density, frequency anddiversity of AMF spores from soil under

Controlled burning is often used to improve plant structure on rangelands adapted to fire. However, possible damage resulting from post-fire grazing to reappearing desirable plant species may be a serious issue hindering usage of this method. Axillar

Direct assessment of competitive ability and defoliation tolerance in perennial grasses

Autor: Carlos Alberto Busso, Oscar Alberto Montenegro, Oscar Abel Bravo, G. D. Rodriguez, Hugo Dosindo Giorgetti, C. Saint Pierre, Tomás Montani

Publikováno v: Canadian Journal of Plant Science. 84:195-204

Stipa clarazii is a dominant, late-seral perennial grass species under exclosure or lightly grazed rangelands in semiarid Argentina, whereas S. tenuis and S. ambigua are earlier-seral perennial tussock grasses. Recent studies have demonstrated that l

Root proliferation of desirable (Stipa clarazii andS. tenuis) and undesirable (S.ambigua)perennial grasses was studied in semiarid rangelands of Central Argentina(40°39′S, 62°54′W) in 1998. On 17 September, soil coreswereremoved from the edge o

Impacts of six initial treatments and rainfall on maximum above-ground herbaceous standing crop were assessed in 1978 and annually from 1984 to 1992 in rangelands of east-central semi-arid Argentina. Treatments applied in 1977–1978 were: (1) untrea

Control of rangeland grasshoppers with flaky wheat bran treated with diflubenzuron and carbaryl was tested in South Dakota during 1988 and 1989. Diflubenzuron (0.75 or 1.0% [AI]/kg) was delivered at 1.1 and 2.2 kg/ha and carbaryl (2.0% [AI]/kg) at 1.
