... Methods Models were delineated from micrographs of the Hartig net and from possible alternatives in growth of hyphae (Fig. 3). Area, perimeter and length of hyphal walls of the models ... hyphae is again enlargedl by compartmentation into Hartig net lobes. It can be concluded from the calculation of the surface/volume ratio that the l...
