Determination of the influence of herbicides on dicotyledons plant transpiration using the sap flow method

Popis výsledku v původním jazyce

Physiological parameters are sensitive and provide information on the toxicity of herbicides in plants. The impact of herbicide application on plant transpiration was evaluated by the sap flow method during 2009?2011. The aim of this work was to verify the sap flow method for determining the effect of herbicides on the basis of continuous measurements of the transpiration flow. Helianthus annuus was used as a model plant species. The two different herbicides tested in this study differed by the effect of active ingredients bromoxynil and clopyralid. The water flow was measured using sap flow meter T4.2. The impact of herbicides was assessed by comparing measured transpiration rate (Q) after herbicide application with an extrapolation of transpiration rate of plants before herbicide treatment (Qcalc). After treatment with bromoxynil the Q values decreased significantly compared to Qcalc. For plants treated by clopyralid, the decline of actual transpiration (Q) compared with the modelled
