Abstract

Thylakoid membranes from higher plants can serve as a fast, specific sensitive and cost effective indicator for herbicides. Photosystem II active herbicides inhibit the electron transport and cause excessive excitation which consequently results in increased fluorescence emission. Within a few minutes the photosynthetic electron flow of a thylakoid sample mixture can be measured as fluorescence yield. Contaminating herbicides in the sample are calculated as cumulative parameter of all active compounds.
