Fig. 3From: Effects of application of trans-zeatin on tracheid differentiation in mature sugi (Cryptomeria japonica) treesEffect of applied trans-zeatin in August on radial variation of microfibril angle (MFA). Variation of MFA were measured at the every 0.1 relative distance from the application point to end of annual ring. The MFAs in three parts (0.1–0.3, 0.4–0.7 and 0.8–1 relative distance) were compared between the treatment and control groupsBack to article page
