Light micrographs showing transverse images of the current year’s earlywood vessels and differentiating xylem of Q. serrata and R. pseudoacacia on 9th May. Many mature earlywood vessels and differentiating vessel elements were observed 6 m (a) and 2 m (b) above the ground in the stem in Q. serrata. Mature earlywood vessels and differentiating vessel elements were observed 6 m above the ground (c) and formation of earlywood vessels in the first row was observed 2 m above the ground (d) in R. pseudoacacia. Bars 200 µm (a, c, d) and 300 µm (b)
