Distribution of endogenous indole-3-acetic acid and compression wood formation in reoriented branches of Douglas-fir

Five-year-old segments of intact 7-year-old branches of Douglas-fir (Pseudotsuga meziesii [Mirb.] Franco) were reoriented to determine the relations between indole-3-acetic acid (IAA) and the formation of compression wood.
