SummaryAn improved technique for measuring electric potential differences on the etiolated Avena .coleoptile is described. An electric wave has been observed to travel down the coleoptile at a speed of up to 14 mm/hr. The wave is observed either follo-wing illumination of the intact coleoptile or following application of 3·indolylacetic acid to the cut top. The wave appears to be associated-intimately with the stream of auxin being translocated. The mechanism of auxin translocation is considered in relation to the wave. It is suggested that the electric wave may be useful as a bioassay for auxin.

“…Regardless of the dosage of light applied or the original orientation of the longitudinal polarity, the general tendency is for the apex to become more negative to the basal regions (the curves in figure 2 A and curve L in figure 5 A are exceptions). Uniform illumination with a dosage of about one million mes has the opposite effect on the longitudinal polarity of the coleoptile (1,9). This fact, however, does not necessarily represent a contradiction because of the large differences in the dosages of illumination.…”

“…This phenomenon is triggered on the plant by the periodic changes of light and darkness from the light source. With such condition, a plant can generate a potential difference as much as 50mV [8–9]. Respiration in plants, on the other hand, is a reversed process of photosynthesis.…”

Characterization of Aloe Barbadensis Miller leaves as a potential electrical energy source with optimum experimental setup conditions

Electrical energy can be harvested from the living plants as a new potential renewable energy source. Characterization of the electrical signal is needed to enable an optimum energy harvesting setup condition. In the present paper, an investigation is conducted to analyze the characteristic of Aloe Barbadensis Miller (Aloe Vera) leaves in terms of electrical energy generation under specific experimental setups. The experimental results show that 1111.55uW electrical power can be harvested from the Aloe Vera with 24 pairs of electrodes and this energy is capable to be stored in a capacitor. This energy has a high potential to be used to power up a low power consumption device.
