Inclusion into the medium of 5 mg•dm-3 of non-ionic (ENF) or ionic (DBST) surfactant caused 50-60% inhibition of nitrite reductase MR) activity in S. polyrrhiza. At the same time, increased accumulation of NO2- in the plant tissues and lowering of the total and soluble protein contents were found. DBST also lowered the nitrate reductase (NR) activity and the dry mass of the plants
