 Title    Physiological Activity of Some Aminophosphonates  
 Abstract    Influence of some new am inophosphonates on electrolyte leakage from cucumber (Cucu­ mis sativus cv "Wisconsin") cotyledons as well as on the content of chlorophyll and activity of guaiacol and pyrogallol peroxidase were studied. Concentration of malondialdehyde (M DA), one of the end-products of lipid peroxidation, was also measured. It was found that am inophosphates influenced the param eters observed to various extents, depending on their structural features and the concentration used. Most active modifiers were those possessing sufficiently long hydrocarbon substituents at the nitrogen atom and/ or iso-propyl chain at the phosphorus atom.

 Title    The Diphenyl-Ether Herbicide Oxyfluorfen: A Potent Inducer of Lipid Peroxidation in Higher Plants  
 Abstract    Measurements o f ethane and ethylene as indices o f in vivo lipid peroxidation and o f chemically-induced stress, respectively, were done on mustard seedlings (Sinapis alba), treated with oxy-fluorfen[2-chloro-l-(3-ethoxy-4-nitrophenoxy)-4-(trifluorom ethyl)benzene]. W hen seedlings were exposed to low light intensity o f 14 W /m 2, only stress-ethylene production but not per­ oxidative ethane evolution was significantly higher over 1 0 days in herbicide-treated seedlings than in the untreated control. Exposure to high light intensity o f 390 W /m 2 did not increase stress-ethylene production in oxyfluorfen-treated plants after 24 h. Lipid peroxidation, however, measured as ethane evolution, was substantially higher after 24 h in herbicide-treated plants, exposed to high light intensity, than in the control, and peroxidation was directly related to strong oxidation o f antioxidants and to severe membrane dam age.

 Title    Binding and Peroxidative Action of Oxyfluorfen in Sensitive and Tolerant Algal Species  
 Abstract    Peroxidative activity of oxyfluorfen and binding o f this nitrodiphenyl ether to cell fractions was investigated with the susceptible alga Scenedesmus acutus and the resistant alga B um illeriopsis filiform is. A lthough a 10-fold higher concentration o f oxyfluorfen was applied to Bum illeriopsis, the lag phase for initiation o f peroxidative evolution of short-chain hydrocarbons from fatty acids was much longer than found with Scenedesmus. Oxyfluorfen was predominantly recovered after hom ogenization from the pellet which was separated into a lipid and a chloroform /m ethanol insoluble fraction. Parts o f the oxyfluorfen which is present in the insoluble pellet fraction during the lag phase before the onset o f peroxidation can be found in the lipid fraction when measurable peroxidative activities have started. This was observed with Scenedesm us as well as with B um il­ leriopsis. During peroxidation initiated by oxyfluorfen acyl lipids are degradated as m onitored by the disappearance o f the plastidic sulfolipid. Analysis o f bound fatty acids showed that they are targets for peroxidative reactions in acyl lipids. Destruction o f polyunsaturated fatty acids was higher than for saturated ones.
