Leaf area index (LAI) assessment in Pinus elliottii var. elliottii and Pinus taeda plantations
Leaf area index was estimated in 6 yr-old slash (Pinus elliottii Engelm. var. elliottii) and loblolly pine (P. taeda) plantations, affected by intensive fertilization and weed control. Three indirect approaches were applied: two yr needlefall production, dimensional analysis and canopy light interception measurements. Similar results were obtained with

Purification and Characterization of Colophony Extracted of Pinus elliottii (Engelm, var. elliottii)
This study reports the purification and characterization of the colophony. The method involves the step of water washing and solubilization of the extracted resin of Pinus elliottii Emgelm, elliottii variety on ethanol to the filtration for removal of solid residues (sand, leaves, pieces of the branch, etc.).
