Online published on 13 January, 2016. Abstract All the carbon sources tested exhibited varied of radial mycelial growth and sporulation of the test pathogen. However, highest radial mycelial growth (86.00 mm) and excellent (++++) sporulation was recorded on Glucose, followed by on Maltose (82.83 mm) and Starch (80.33 mm) with excellent (++++) sporulation. All the nitrogen sources exhibited varied of radial mycelial growth and sporulation of the test pathogen. However, highest radial mycelial growth (82.55 mm) and excellent (++++) sporulation was recorded on Potassium nitrate, followed by on Peptone (75.83 mm) with good (+++) sporulation. Least radial mycelial growth (19.00 mm) was recorded on Urea with poor (+) sporulation. Top Keywords Nutritional studies, mycelial growth, sporulation, A. carthami. Top |
