Endogenous distribution of indole-3-acetic acid (IAA) in hypocotyl cuttings from 21-day-old Pinus radiata seedlings. Transverse sections from the base of hypocotyls after 24 h of culture in the presence of 10 μM indole-3-butyric acid (IBA) (A, B, C, D) or in the presence of 10 μM IBA + 10 μM 1-N-naphthylphthalamic acid (E, F, G, H). A, E) Differential interference contrast (DIC) image, B, F) Immunodetection of IAA, C, G) DAPI nuclear staining, D, H) merged immunodetection of IAA and DAPI staining. c, cambial region; co, cortex; r, resin canal; x, xylem.
