We report what we believe is the first experimental limit placed on plant biomagnetism. Measurements with a sensitive atomic magnetometer were performed on the Titan arum (Amorphophallus titanum) inflorescence, known for its fast biochemical processes while blooming. We find that the magnetic field from these processes, projected along the Earth’s magnetic field, and measured at the surface of the plant, is ≲ 0.6 μG.

The authors are indebted to the University of California Botanical Garden staff who generously granted after-hours access to the garden facilities. We also acknowledge stimulating discussions with Robert Dudley from the department of Integrative Biology, with Lewis Feldman, Steve Ruzin, and Peggy Lemaux from the department of Plant and Microbial Biology, and with Philip Stark from the Department of Statistics, at University of California at Berkeley. Invigorating exchanges with our colleague Todor Karaulanov helped the understanding of the processes at hand. This project was funded by an ONR MURI fund and by the U.S. Department of Energy through the LBNL Nuclear Science Division (Grant No. DE-AC03-76SF00098).|
