Última Influence of woody species on aerial growth of perennial grasses in semi-arid rangelands of central Argentina Phyton Blazquez,FR; Peláez,DV; Andrioli,RJ; Elia,OR. The interaction between woody and grass species in semi-arid rangelands of central Argentina was assessed through the evaluation of the impact of woody species on grass growth over a 2-y period. The study comprised two morpho-physiologically different woody species and two cool-season perennial grass species highly preferred by domestic livestock. The study involved the assessment of total green length (TGL) and number of green leaves (NGL) per tiller in grasses growing beneath the canopy of woody species and in open rangeland areas. Soil temperature, pH and water, nitrogen, phosphorus and organic matter content were estimated at the same study sites. Precipitation during the study period was also recorded. Woody species induced higher TGL of grasses... Tipo: Info:eu-repo/semantics/article Palavras-chave: Canopy architecture; Soil temperature; Soil water content; Tiller green length.

Plant growth in semiarid rangelands may be affected by time grazing is excluded during the post-fire regeneration period. The objective of this field work was to study the effect of post-fire defoliation at different phenological stages [vegetative (early-season defoliation) and internode elongation (late-season defoliation)] on growth of Piptochaetium napostaense and Poa ligularis, two very important perennial native grasses in the temperate semi-arid region of central Argentina (Caldenal). In general, the post-fire defoliation treatments did not affect the number of green leaves on tillers of P. napostaense. Early-season post-fire defoliation generally reduced the number of green leaves on tillers of P. ligularis in comparison to those in control plants....

Fire is a major ecological process within most terrestrial ecosystems. Therefore, understanding the vegetation response to fire is essential to its management. Our objective was to study the effect of a controlled fire, conducted at the end of summer season, on cover and density of the most common woody and herbaceous species in Phytogeographical Province of the Monte, Argentina. In general, after the control fire, the woody species mean percentage cover was significantly lower (p<0.05) in the fire treatment than in the control (no controlled fire). This effect was persistent during the study period. No significant differences (p&gt;0.05) were detected in woody species mean density among treatments throughout the whole study. Desirable perennial... Tipo: Info:eu-repo/semantics/article Palavras-chave: Controlled fire; Desirable grasses; Undesirable woody species; Monte region; Argentina.
