Effect of host substrate on germination and growth of Verticillium albo-atrum and V. dahliae conidia and mycelia
Transactions of the British Mycological Society 71(3): 483-489
The method of assessing fungal colonization of diseased plants by tissue maceration and colony counts was tested in recovery experiments using mycelium and conidia of V. dahliae and V. albo-atrum with tissue of chrysanthemum and tomato, respectively. Maceration of 1st internode chrysanthemum stem with mycelial propagules increased colony numbers between 10- and 13-fold. Combined separate macerates of host and fungus were less stimulatory.
