[Slow fluorescence induction and productivity of barley treated with supercritical fluid extract of amaranth].

It is shown that treatment of barley plants with supercritical fluid extract of amaranth results in the increased fluorescence parameter (F(M) - F(T))/F(T) of slow fluorescence induction curve of the leaf. Barley treated with the extract showed higher productivity and higher indices of the yield.

[Slow fluorescence induction and CO2-exchange in bean leaves treated with Reynoutria sachalinensis extract].

It has been shown that the treatment of bean seedlings with a water extract of Reynoutria sachalinensis increases visible photosynthesis and the activity of dark respiration of plants. The increase in CO2-uptake under relatively high light illumination (10000 1x) correlates with an increase in the fluorescence parameter (F(M) - F(T))/F(T).
