Chemical Composition of Second Rotation Populus Hybrid NE-388

The influence of management strategy and rotation on specific gravity and chemical content (extractive, holocellulose, alpha-cellulose, and Klason lignin) values for second rotation 4-year-old Populus Hybrid NE-388 wood and bark specimens were investigated. Specific gravity values for wood were lowest for fertilization and fertilization/irrigation strategies and for bark were highest for fertilization and fertilization/irrigation strategies compared to control and irrigation strategies. Management strategies had little effect on the holocellulose and alpha-cellulose values for the second rotation. Management strategy and rotation had significant effects on extractive and Klason lignin contents for bark and the extractive content for wood. Second rotation average specific gravity values for wood were similar to or higher than first rotation values and average Klason lignin content values for bark were higher than first rotation values.
