Brown (1973) also reported lignin deposition in the injured citrus peel. Significant deposition of lignin was noticed around the wounds inoculated with Geotrichum candidum in lemon peel .
Some changes were observed at the wound and in surrounding peel tissues after 1-4 days of wounding in satsuma mandarins.
The lignin-like material (L-LM) is induced by wounding of fruit in cucumber and impedes the hyphal penetration of Penicillium in lemons .
