2.3. Morpho-physiological studies
Morpho-physiological observations of the isolates were made
from day 2 to day 6 of cultivation on PDA at 20 C or 25 C. Isolate
identification was based on colony colour, pigmentation of reverse
side and odour; sporulation type, conidia shape, colour, and
dimension; growth rate and optimal growth temperature. Growth
rate of the isolates was defined by measuring colony diameter
every day for 72 h. The effect of temperature on growthwas studied
on isolates grown on PDA in darkness at 15, 20, 25, 30 and 35 C for
4 days.
