Abstract

Surface of intact lamina in eggplants was exhibited changes of electric potential when exposed to light. The changes of electric potential was hardly effected on light wavelength, the same patterns were observed with blue, green and red lights. The amplitude of first positive phases ware saturated more than about 100μmol/m²/s of light intensity, and the decrease in response times were obseved with increasing light intensity. But, that of second negative phase was increased as light intensity rised. Like photosynthetic rate, correlation was observed between the amplitude of second negative phase and light intensity, and the second phase of light-induced changes of electric potential and photosynthetic rate were strongly repressed with abscisic acid (ABA).
