Abstract

The electrical signal in plants could be related to its physiological responses but there is a lake of scientific results about it in the literature. Even for plants with commercial importance. So, it is important the analysis of oscillatory characteristic in bioelectric signals from plants. The presence of the oscillatory electric generator was shown using a classical power spectral density. The Lempel and Ziv complexity measurement showed that the plant signal was not noise despite its nonlinear behavior. The oscillatory characteristics of the plant signal have been studying by the LAFAC team when the author of this proposal will work. So, the nexte step of this study is the investigation of bioelectrical activity in Oliver plant.
