Arbuscular mycorrhizas increase survival, precocity and flowering of herbaceous and shrubby species of early stages of tropical succession in pot cultivation. Repositório Alice
RONDINA, A. B. L.; LESCANO, L. E. A. M.; ALVES, R. de A.; MATSUURA, E. M.; NOGUEIRA, M. A.; ZANGARO, W..
Arbuscular mycorrhizal fungi (AMF) are an important biotic factor that influences tropical ecological succession and differently affect the woody species belonging to different successional stages. However, little is known about the influence of AMF on growth and reproduction of herbaceous and shrubby species of early phases of tropical succession. Thus, we assessed the effect of AMF on the development of 27 heliophilous herbaceous and shrubby tropical species. Plants were grown in greenhouse, in low- and high-fertility soils, with or without AMF, for 100 d. Most species grown with AMF exhibited high root infection intensity (80%), irrespective of soil fertility. In the low-fertility soil, non-mycorrhizal plants exhibited about 88% less shoot dry mass...

Infection intensity, spore density and inoculum potential of arbuscular mycorrhizal fungi decrease during secondary succession in tropical Brazilian ecosystems. Repositório Alice
ZANGARO, W.; ANSANELO, A. P.; LESCANO, L. E. A. M.; ALVES, R. de A.; RONDINA, A. B. L.; NOGUEIRA, M. A..
Little is known about the relationship involving arbuscular mycorrhizal (AM) fungi and functional groups of plants that characterize different phases of tropical succession.We appraised the AM infection intensity of root cortex and spore density in the soil in sites over tropical successional gradients (grassland, secondary forest and mature forest) for several years in Araucaria,Atlantic and Pantanal ecosystems in Brazil. The intensity ofAMinfection decreasedwith advancing successional stages in all ecosystems and it was around 60?80% in early stages of succession, 37?56% in secondary forests and 19?29% in mature forests. Similarly, the AM spore number also decreased with advancing succession and was the highest in early stages (73?123 g?1), intermediate...
