Light micrographs showing transverse and radial images of differentiating vessel elements in Q. serrata on 16 April. Vessel elements with deposition of secondary walls were observed at the top (a) of the stem and 6 m above the ground (b). Radial images show partial perforation (arrow no end wall) and end walls (asterisk) in vessel elements at the top (c) of a stem. End walls of vessel elements (arrows) were found in the stem 6 m above the ground (d). Enlarging vessel elements were observed 4 m (e) and 2 m (f) above the ground and near the ground (g). Bars 50 µm (a), 100 µm (b, c) and 200 µm (d–g)
