I am working on the effect of fungicide that could have on Alternaira sp (A.solani , A.tomatophila and A.grandis), and I have remarked different results, it means that i could separate between them using a morphological aspects like a color, mycelia aspect, etc.
So my question is: can we use this aspect in order to distinguish between them ?
Narimene,
Reaction of particular strain to biocide is a common taxonomic test in bacteriology. It is less known for use in mycology.
Alternaria spp. have some interspecies diversity in fungicide reaction (just as example: http://agronomy.emu.ee/vol04Spec/p4S57.pdf) as well as intraspecies variation (see http://www.satishserial.com/issn0973-4880/chapter33.pdf). You have to test at least 30 isolates of different geographic origin per each species to confirm that such trait is a valid taxonomic feature.
See some other reports: http://gcirc.org/fileadmin/documents/Proceedings/IRCWuhan2007vol4/87-89.pdf
