There is mounting evidence that much of the plant growth response to endomycorrhizal infection is due to increased uptake of slowly diffusing ions such as phosphate as a result of increased soil exploration by hyphae (eg. Sanders & Tinker, 1971; Hattingh et al., 1973). Something also needs to be known about the physiology of the mycorrhizal system: what are the relative mycorrhizal plant use its absorbed nutrients in the same ways as the uninfected plant? what is the partitioning between root and shoot? what is the biochemical fate of absorbed phosphate? Do endomycorrhizas behave similarly to ectomycorrhizas and act as aphosphate storage sink? In previous studies with radioactive isotopes endomycorrhizas greatly increased phosphate and zinc absorption from solution (Gray & Gerdemann, 1967; Morrison & English, 1967; Bowen & Mosse, 1969; Bowen et al., 1974). We have extended the use of radioactive isotopes to answer some of the questions raised above. |
