Aporte e decomposição da serapilheira e produção de biomassa radicular em florestas com diferentes estágios sucessionais em Pinheiral, RJ

Abstract: RESUMOEste estudo objetivou avaliar a deposição e decomposição da serapilheira e a produção de biomassa radicular de três fragmentos florestais em diferentes estágios sucessionais (avançado, médio e inicial) localizados no município de Pinheiral, RJ. Para interceptação da serapilheira instalaram-se em cada fragmento, dez coletores cônicos. Avaliou-se a biomassa radicular em dois períodos (chuvoso e seco), amostrando-se pelo método do monólito, em 0-10, 10-20 e 20-30 cm e dez repetições por profundidade. Não oc… Show more

“…Theses climatic variables are particularly important for trees ecophysiology, once they also regulate gases changings between plant and atmosphere and thus physiologic process into de plants. Menezes et al (2010) also found a negative correlation between litterfall production and relative humidity, however, the authors found a positive correlation between the deciduous material and rainfall precipitation. For these authors, the long period with low temperatures and low winter rainfall regimes reflect a high fall of leaves early in the season of spring, when it starts to rain in the region and temperatures increase.…”

“…This might also be a response triggered by hormonal mechanisms (PEZZATTO; WISNIEWSKI, 2006), in which the sensitivity by the lack of water in the soil may trigger physiological, morphological and structural changes. Other papers also reported this water-saving strategy for plant community, as reported in the work de Menezes et al (2010) and Sanches et al (2009).…”
