1Radial growth was determined as average of two runs of experiments on radial colony growth of B. fabae.
2Linear radial growth rates were estimated as the slope of the following function: Colony diameter = Radial growth rate x time + b.
Means of colony radial growth in the same column followed by the same letters are not significantly different (P<0.05). The values in the table are based on untransformed data of radial mycelial growth from two runs of experiments.
