Use of chlorophyll fluorescence induction kinetics to study translocation and detoxication of DCMU-Type herbicides in plant leaves

Abstract

Transient levels of the fluorescence induction rise were used to quantify partial photosynthesis inhibition by DCMU-type herbicides in whole leaves. Assays in different crop or weed species showed a good accuracy in measurements (generally, variation was lower than 5%). This technique was applied to the problem of varietal selectivity of wheat towards chlortoluron. © 1984, Walter de Gruyter. All rights reserved.
