Examples from the Web for growth rate
With the precautions described the growth-rate in vigorous specimens is found to be very uniform.
Under continuous lowering of temperature the growth-rate became slowed down till at 21C.
The optimum temperature is at 34C., after which growth-rate declines and becomes completely arrested at 58C.
The conditions of the experiment would thus become more precise if the growth-rate in the absence of light is taken as the normal.
