| Abstract:
Important loss induced by Erwinia chrysanthemi occured in France on imported and French Dahlia tubers vegetatively propagated, mainly under glass, during the propagation period. About 600 symptomless cuttings of 37 more or less sensitive cultivars are tested for the presence of Erwinia chrysanthemi using 3 methods, on basal stem pieces :
