Summary Injuries induced by systemic infections with Peronospora tabacina Adam in tobacco plants The author describes the macroscopic and microscopic symptoms (particularly at the base of the stem) after systemic infections of Peronospora tabacina in resistant and susceptible tobacco plants. The mycelium of the pathogen could be demonstrated in the vessels of stem and leaves; stem and leaves furthermore showed deformities and necrosis. The relationships between the two groups of symptoms and the causes for the absence of conidial formation in resistant plants (which in other respects displayed the symptoms described) are discussed.
