Caracterização microclimática no interior dos talhões de <i>Eucalyptus camaldulensis</i> Dehnh, <i>Eucalyptus grandis</i> Hill ex Maiden e<i> Eucalyptus torelliana</i> F. Muell, localizados em Anhambi, SP.

Abstract: RESUMONeste estudo, avaliaram-se algumas características microclimáticas em talhões de E. camaldulensis, E. grandis e E. torelliana, resultantes dos diferentes tipos de cobertura florestal que estas espécies propiciam. Das três espécies estudadas, E. camaldulensis foi a que deixou passar as maiores quantidades de radiação solar e intensidade luminosa. Já E. torelliana foi a espécie que mais interceptou a radiação solar e deixou o sub-bosque com menos luminosidade. As maiores temperaturas diárias e nos primeiro… Show more

“…In the case of the eucalyptus, its ellipsoidal shape, with spaced branches, facilitates the solar incidence on the surface of the soil, with less radiation-blocking and increased energy flow. Indeed, according to Schumacher and Poggiani (1993), the incident sunlight in areas with eucalyptus is greatly reduced, but slightly changed qualitatively, reaching the forest canopy and being reflected back to the environment. In broadleaf trees such as Cambará and Cumbaru (ICLF-3), however, the light undergoes selective absorption, modifying its use and even the photosynthetic processes.…”

“…However, it is a mistake to consider the uniqueness of quantitative and qualitative characteristics of natural shading, particularly in integration systems, as the efficiency of the understory microclimate modification is linked mainly to the morphological characteristics of the tree species used as well as to its density (Schumacher and Poggiani 1993;Silva and Maia 2013).…”

“…In the evaluation of litter production in 7 -10-yearold E. saligna stands by Poggiani (1985) and in 7-year-old E. grandis stands by Schumacher (1992), the deposition of deciduous material and nutrients was greatest at the end of spring and summer, in the warmest and wettest periods. This pattern shows that the season of greatest litter production in eucalyptus stands coincides with the rainy season, while in areas with native species, litter production is greatest in drier periods (Fernandes et al, 2006;Diniz et al, 2011).…”

“…Esse arranjo também reflete o resultado complexo e dinâmico das interações fisiológicas e evolutivas entre a vegetação e o ambiente (SCHUMACHER; POGGIANI, 1993). É a arquitetura da copa das árvores que afeta a produtividade primária do ecossistema como um todo e regula também a luz, temperatura, vento e umidade sob o dossel e altura do piso florestal (SCHUMACHER; POGGIANI, 1993). Alguns reflorestamentos tendem a apresentar maiores porcentagens de abertura de dossel (TRICHON; WALTER; LAUMONIER, 1998) e isso também ocorre com as florestas em estádios sucessionais iniciais, em que não existem três estratos de vegetação bem estabelecidos, e em áreas que sofreram perturbações recentes.…”
