Fig. 2 in First insights into micromorphology of needle epicuticular waxes of south-eastern european Pinus nigra J. F. Arnold populations

Fig. 2. SEM micrographs of P. nigra epicuticular waxes. A. adaxial surface of needles; B. marginal teeth with mucrones (MC); C. clusters of longitudinally aggregated rodlets (LAR); D. suprastomatal chambers surrounded by alone tubes lying on the surface (AT) as well as individual granules (GR); E. tubes slightly fused to each other (TSF) and tubes fused together (TF), which surround and fill the suprastomatal chambers; smooth layers (SL - amorphous wax that covers the largest area of needles).
