Evaluation location: Washington, United States
Plants were grown from original seed and germinated in a controlled-enviromental chamber (25/15 degree C 16h light/8h dark). After eight weeks growth the endophyte status was determined by isolation on Potato dexstrose agar from basal stem sections. The infection status was established via polymerase chain reaction with specific primers. Conidial length was measured using a scanning electron microscope.
