fibre tracheids surrounding vessels and xylem ray parenchyma were resistant to decomposition.
The axial alignment of tracheids, vessels, fibers, radial arrangement of the xylem ray parenchyma allow to wide spread distribution of hyphae whitin the xylem [15,22,7,6].
Therefore, the transfer of photosynthates into xylem rays is to be expected, and from rays, flow of solutes into axial parenchyma can occur (Holt, 1975).
