Permanent Magnetic Field and Plant Leaf Temperature

We investigated the effect of a permanent magnetic field as an environmental factor on fluorescence spectra and temperature of intact plant leaves. It has been shown that magnetic fields can induce significant changes in fluorescence spectra and leaf temperature. The fluorescence intensity ratio (FIR) and change of leaf temperature T increase with the increase of magnetic field intensity. The increase of T due to magnetic fields is explained with a simple model. Reasonable agreement between calculated T, based on the model, and measured T was obtained.
