GROWTH AND SPORULATION OF Septoria carvi Syd. IN DIFFERENT CULTURE CONDITIONS
2012
Zalewska, Ewa
The quantity and quality of the herb material are reduced by pathogenic fungi. In the case of caraway this pathogen is Septoria carvi. In the vegetation periods the fungus occurs with varying intensity, which is related to the requirements of life. The present study found that the growth of fungal colonies is possible at the temperatures from 0 to 30°C, the optimum being from 20 to 25°C, and sporulation is possible at the temperatures from 10 to 30°C, with the optimum at 25°C. It was shown that the most useful medium for the isolation of S. carvi from caraway plants is malt medium and malt medium with decoction of the leaves of this plant. Pycnidia and conidia of the fungus, which are necessary to identify the species, are formed the fastest on the malt medium with decoction of the leaves or schizocarps of caraway and on PDA medium and it is these substrates that should be used for the cultivation of S. carvi.
