Variation of stem volume and wood density of provenances of Pinus oocarpa and P. patula ssp. tecunumanii at Agudos, Sao Paulo, Brazil
A provenance trial of Pinus oocarpa schiede / P. patula schiede and Dappe ssp. Tecunumanii (Eguiluz and Perry) styles of the International series coordinated by the Oxford Forestry Institute, University of Oxford, England, was established at Agudos, São Paulo, Brazil, in 1972. In 1979, the trial was assessed for wood density (DEN) and volume under bark (VUB) and these two traits plus the derived indices of within sample density variation (VAR) and dry matter .index (DMI) were analyzed statistically, there were significant differences (p<.01 between provenances for var vub and dmi. of p. patula spp. tecunumanii were superior to oocarpa in terms></.01>
