Microfibril angles in the root wood of Pinus radiata and Pinus nigra

, : Microfibril angles in the root wood of Pinus radiata and Pinus nigra. IAWA Journal 22(1): 57-62

Microfibril angles of the S2 layer and tracheid lengths were measured in the root wood of 10-year-old Pinus nigra, and the root and stem wood of 18-year-old Pinus radiata. Within 10 mm (the first 2-3 growth rings) from the root centre, microfibril angles were large in the wood of both species, ranging from 25 degrees to 40 degrees. Beyond 10 mm (the fourth growth ring and beyond) from the root centre, microfibril angles were small.
