Successful single spore initiations were obtained only on Harvey and Grasham (4) basal medium amended with 0.1 g/L CaCO 3 , 1 g/L each of yeast extract and peptone, and 10 g/L of bovine serum albumin (HGYP+BSA). Nurse culture techniques were necessary for significant numbers of successful colony initiations (...)}, number={10}, journal={PHYTOPATHOLOGY}, author={HU, A and AMERSON, HV}, year={1991}, month={Oct}, pages={1294–1297} }
