Plant Physiology and Cultivation Studies

We studied wood anatomy and specific gravity in a total of 18 trees of Ocotea curucutuensis , a recently described species, lacking wood anatomical information. Nine sample trees were obtained in each of two areas, Pico do Itapeva (PI) and Núcleo Curucutu (NC), both in the state of São Paulo, Brazil. These areas have marked differences in precipitation, altitude, and temperature. Anatomical differences between the two populations appeared related to tree size, and possibly indirectly to climate. Higher wood specific gravity related with the smaller diameter in NC trees is hypothesized to contribute to mechanical support of the epiphyte-laden trees and to resistance against the prevailing strong winds.
