Fig. 3From: Effects of crown length on indole acetic acid (IAA) amounts in cambial region tissues in lower and upper trunks of sugi cultivars (Cryptomeria japonica) in SeptemberIAA amounts in cambial region tissues of sugi cultivars. There was a significant difference in the IAA amounts between the lower trunk and upper trunk (p < 0.01). Lower trunk a point 1.2 m above the ground, upper trunk a point 7.0 m above the ground (sugi cultivars)Back to article page
