Fig.24.4. Action potentials in soybean induced by irradiation at 470 nm in direction B as
shown in Fig. 24.1. The irradiance was 8.5 µE/m 2 s. The distance between electrodes was
5 cm. The soil was preliminarily treated with water every day. The volume of soil was 0.5 L.
The frequency of scanning was 50,000 samples/s.

in a continuously varying environment only if all cells, tissues, and organs
function in concordance (Volkov et al. 2002).
These propagating excitations are theoretically modeled as traveling
