Fig. 3From: Wood density and microfibril angle from pith to bark of a sugi cultivar (Cryptomeria japonica, Japanese cedar, Tosaaka) grown in a Nelder plotEffects of initial tree density on ring width. Each plot shows an average value in a ring number among sample trees of each tree density zoning symbol. Number of sample trees of each initial tree density zoning symbol range from five to nine. Initial tree density zoning symbols were the same, as shown in Table 1Back to article page
