Última Effect of post-fire defoliation on growth of two native grasses in the Caldenal, Argentina Phyton Peláez,DV; Bóo,RM; Mayor,MD; Elia,OR; Martínez,SA. 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.
