Abstract
SUMMARY: The relationship between various parameters of growth of Neurospora crassa on solid media in tubes is described. These are (a) the relationship between culture weight and linear growth rate on various media; (b) the relationship between ‘lag’ in growth and inoculum size on various media. This latter relationship appears to obey a log law, enabling an inoculum doubling-time to be calculated. Adaptation of the arginine auxotroph arg-I (46004) to diminution of arginine in the medium first occurred by decrease in mycelial weight and then by decrease in linear growth rate. The inoculum doubling-time did not appear to vary systematically with arginine concentration.
