Figure 1From: Differences in intra-tree variation in spiral grain angle for radiata pineTilt adjusted spiral grain angles grouped horizontally by clone and vertically by annual growth increment. Ramets are distinguished by colour, with ramet 1 being red and ramet 2 being blue. Each line corresponds to a different radius, four orthogonal radii per disc. Note that, for the sake of clarity, annual growth increments 1, 2 and 7 have been omitted.Back to article page
