S ummary The effect of temperature on the rate of phosphorus translocation, on the uptake and metaholism of phosphate and on respiratory rate of Rhizopus stolonifer , has been studied. Over the temperature range 20–30° C the rate of phosphorus translocation is greatest at 20° C and lowest at 30° C. The rate of oxygen uptake is greatest at 25° C. The rate of phosphate uptake does not vary significantly over this temperature range, but the proportion of ahsorhed phosphate present as orthophosphate bears a direct relationship to the rate of phosphorus translocation. These results are consistent with the view that phosphorus may be translocated in the form of orthophosphate.
