Abstract
- The effects of different light quality on the change of membrane potentialdifference (PD) of the guard cell in the intact leaf have been investigated. The mem-brane PD was about -5.5 mV by white light of 600 moles m-2 s-1. The mean PD ofchange caused by red light was about -5.2mV at the light intensity of 80 moles m-2 s-1.Membrane PD of guard cells in response to blue light was saturated at low light inten-sity. However, red and green light enhanced the change of membrane PD of guard cellswith increasing light intensity. In green light the biggest change of memrane PD wasaround -4 mV, whereas, with blue light the change of of memrane PD was around -2mV. Accordingly, the membrane PD of guard cell showed the different degree of hyper-polarization by each wavelength.
