Soil fungal flora
The abundance and physiological activity of the fungal flora of
ditl’erent habitates vary considerably. and the community and its
biochemical activities undergo appreciable fluctuation with time at any
single site. Both the generic composition and the size of the flora vary
with the type of soil and its physical and chemical characteristics.
Considerable etl’orts has been directed toward the establishment of the
composition of the fungus flora of the soil. Mycologists in many countries
have pertonned extensive and uncountable studies of the genera and
species that dominate in one or another ecological circumstances, and the
results of their efforts have borne fruits
Although the entire dominant flora is not always well defined, a
clear picture of the timgus inhabitants is now emerging .For purpose of
enumeration. conventional plate counts have been most widely used,
although the results are tar !rom unequivocal. This procedure permits a
degree of quantitication. Such estimates of microbial density reveal the
presence in soil of populations typically ranging fi·Oin as few as 20.000 to
many as I 000 000 fungal propagules per gram, the propagule being
considered as any spore, hypha or hypha! tragment that is capable of
giving to a colony ( Alexander. 1977) .
