Description

The typical physiological parameters caused by the so-called peroxidizing herbicides, namely (1) growth inhibition, (2) chlorophyll decrease, (3) accumulation of protoporphyrin IX, (4) short-chain hydrocarbons formed through peroxidatioe destruction of membranes, and (5) alleviation of peroxidation by adding gabaculine (an inhibitor for the formation step of 5-aminolevulinate which is a precursor of protoporphyrin IX) and diuron (an inhibitor of photosynthetic electron transport), were obtained using habituated Nicotiana glutinosa (HNG) cells. The date correlated well with the physiological parameters assayed by unicellular microalgae, Scenedesmus acutus. Since the HNG cells are of a higher plant and its handling is rather easy for culture and phytotoxic assay of the herbicides, the assay system using the HNG cells is considered to give a convenient method for this sort of peroxidizing herbicides.
