Fig. 22. Fluorescence micrograph of peach tissues inoculated with L. persoonii. Fig. 22. Transverse section of a portion of the ligno-suberized boundary zone and new periderm (NP) adjacent to peach bark tissue colonized by L. persoonii (from right) showing altered phellem cell shape (arrows). Note contrast between altered tissues in this figure and normal periderm in the previous figure. x800. (From Biggs 1986).
