S ummary The rates of uptake of phosphate by two different kinds of mycorrhiza of Pinus radiata (Fa and Ca) were both greater than that of uninfected roots at all temperatures studied. Over periods of 160 minutes the optimum temperature for both mycorrhizal and uninfected roots was about 25° C, but the uptake rate of type Fa fell off more steeply above this optimum than that of Ca over the same time‐period. Uninfected roots showed, at all temperatures, a more rapid rate of absorption over the first 60 minutes of the experimental period than later.
