Active cambial zone from a microcore sampled in 01.10.2014 showing the cambium and cell enlargement zone (CE) and the wall thickening and lignification zone (LT). The line labelled ‘lignin’ represents the normalized relative lignin autofluorescence. The yellow line labelled ‘width’, the normalized relative cell radial width; and the white line labelled ‘thickness’, the normalized relative wall thickness
