Analyzing the diameter averages at 24 hours (table 2), on PDA culture medium, the
colonies had values between 11,80 mm (Daia and Iernut) and 14,66 mm (Ciurila). The
colonies inoculated on SGA culture medium had an average between 7,57 mm (Motiş) and
10,10 mm (Adrian).
At 48 hours, the reading of the same culture Petri dishes indicated almost a doubling
from the first reading, on PDA culture medium. The minimum diameter, in average of 22,50
mm, was observed in the colonies from Cefa, and the maximum of 30,33 mm in the colonies
from Ciurila (table 2). At the same time interval, compared to the samples from PDA culture
medium, the samples from SGA medium had lower values, with a minimum of 16,00 mm in
diameter (Motiş) and a maximum of 20,70 mm (Adrian). After Stueland and al., 2005,
values of the colonies diameter bigger than 40 mm are indicating the reaching at the growing
edge.
At 72 hours, the diameter averages indicated values bigger than 40 mm on PDA
culture medium, and under this value for SGA medium. The maximum diameter of the
colonies, 57,00 mm, was observed on the 6 samples inoculated from Ciurila, and medium
values of 48,80 mm on the samples collected from łaga (table 2). On SGA culture medium,
