Strawberry amendment to potato dextrose agar to increase conidiation in Cryphonectria parasitica
2014
Double, M.L. | Marshall, MR
Strawberry fruit were incorporated into a potato dextrose agar (PDA) medium in an attempt to develop a medium that would promote conidiation of Cryphonectria parasitica isolates. Two other plant pathogenic fungi (Helminthosporium sativum and Fusarium solani) were also tested. Isolates were grown on PDA and strawberry-amended PDA for 14 d at which time agar plugs were removed to assess conidiation. In most instances, more conidia were produced on the strawberry-amended PDA than on unamended PDA for both virulent and hypovirulent C. parasitica isolates and for Helminthosporium sativum and Fusarium solani.
