Sensitivity of Some Plant Material to Magnetic Fields

  • Douglas W. Dunlop

The effects of magnetic fields on the growth and development of organisms have been studied for over a century. A variety of plant material has been used in such experiments, including both vascular and nonvascular plants. These studies have been largely concerned with growth responses, rather than anatomical effects. The investigations described in this chapter include not only growth responses of a filamentous alga and the adventitious roots of several angiosperms, but also the effects of heterogeneous magnetic fields of 500–4500 Oe on the activity and anatomy of root meristems and the morphogenesis of the derivative cells and tissues of these meristems.
