Abstract
In 3 experiments Lolium perenne was grown in pots of soil, either with Plantago lanceolata or with another L. perenne. The plants were of the same age and they were infected with vesicular-arbuscular mycorrhizas. One L. perenne plant in each pot was labeled with 32P by foliar feeding; radioactivity was subsequently detected in the other plant. Non-destructive measurements made using a scintillation probe showed that after an initial lag, transfer between the plants continued steadily up to 22 days. The mean rate of transfer was 0.7-2.8 .times. 10-3 units of 32P per day per unit of 32P in the donor plant''s root system. When transfer occurs between plants of the same species, age and size this indicates exchange rather than net transfer. The ecological significance of the results is discussed.This publication has 8 references indexed in Scilit:
