Laccase activity in H15 and H20. a to d, H15; e to h, H20. Details of the xylem regions and bast fibres are shown in b and f and d and h, respectively. Orange colour indicates the presence of laccase activity. Blue arrowheads indicate the absence of laccase activity in the lignified primary xylem. i: negative control without DAB in H20. j: negative control with sodium azide as inhibitor of laccase activity in H20. bf1 primary bast fibre, bf2 secondary bast fibre. Scale bar: 100 μm (50 μm in the insets)
