The effect of antibiotics and metabolic inhibitors on mycelial growth of Botrytis cinera was followed. Inhibitors of protein synthesis, chloramphenicol, erythromycin and tetracycline inhibit growth or sporulation of Botrytis cinera. Ethidium bromide, 5-fluorouracil, phenylethylalcohol and K 20 cause granulation, vacuolization and undulation of hyphase. 2,4-Dinitrophenol, boromycin, macrotetrolides, monensin, scopathricin and TX2 at subfungistatic concentrations induce intensive branching of hyphal tips i.e. at the site of synthesis of the cell wall. In older hyphase grown in the absence of the antibiotics the branching begins after their addition, particularly in the septum region. When comparing the results referred to here with those obtained previously and on the basis of literature data it may be assumed that the changes in polarity of growth of Botrytis cinerea might be caused primarily or secondarily by impairing membrane functions and formation of cell walls.
