[Changes in induction of slow fluorescence in leaves of maple located near urban highways]. / Izmenenie medlennoi induktsii fluorestsentsii list'ev klena vblizi transportnykh magistralei.

The slow fluorescence induction parameter FM/FT was measured for green leaves from maple trees grown in the park, depending on the distance (5-65 m) between the tree and the highway cross. We concluded that the decrease in the value of FM/FT for trees grown in the vicinity of the road cross was caused by exhaust gases.

[Effect of inorganic phosphate on photosynthesis in bean leaves]. / Vliianie neorganicheskogo fosfata na rabotu fotosinteticheskogo apparata list'ev bobov.

It was shown that raising pod seedlings by the hydroponics method on KH2PO4 solutions at concentrations between 10(-7) and 10(-5) M leads to an increase in the rate of oxygen release (delta O2/delta t), with the chlorophyll content in leaves being unchanged. The values of the parameters FM/FT of slow fluorescence induction and B/A of photoinduced changes in ESR1 signals from pod leaves correlate with the delta O2/delta t value.
