Abstract

In order to evaluate the physiological damage to plants caused by osmotic stress, we have investigated the relationship between the inhibition of root elongation and spontaneous photon emission from the root. Adzuki bean roots were soaked in polyethylene glycol (PEG) solutions for short periods in their early growth stage, and their root length and photon emission were measured afterwards. Consequently, it became clear that the root elongation decreased with the increase of PEG concentration. Moreover, there was a clear correlation between the emission intensity of the cell division area in the root and the inhibition of elongation, though the elongation of individual roots varied to some degree.
