Studies on Tree Rings, Growth Rates and Age-Size Relationships of Tropical Tree Species in Misiones, Argentina

Abstract

Wood samples of 13 tree species from three sites in the Selva Misionera (Misiones Province, Argentina) were analysed macroand microscopically for occurrence and formation of growth rings. Well-defined annual tree rings were found in Cedrela fissilis Vell., Parapiptadenia rigida Benth., Cordia trichotoma Vell. and Chorisia speciosa St. Hil.
