Effects of temporary light exposure on local electrical potential of the leaf surface (LEP), on CO 2 and on relative humidity (RH) changes within the leaf chamber were recorded with a multi-channel electronic recorder. The results are analyzed by employing the grey relation function ( ξ ) and grey relation grade ( R ) based on the Grey Theory. The analysis shows that LEP could represent the dominant factor in executing the stomatal movement under the light exposure.展开更多
