Schematic representation of the wood-quality measurements. Vertical dotted line represents the year of the partial cutting. Horizontal lines indicate the number and emplacement of the measured rings for the different wood characteristics. Eight years were measured to determine ring width (RW), latewood width (LWW), ring density (RD), earlywood density (EWD), latewood density (LWD), and maximum density (MaxD). Four years were measured to determine tracheid length (TL). Six years were measured to determine lumen area (LA) and wall thickness (WT)
