[Luminescent and physiological indices of triticale under the treatment of seeds with growth regulators].

It is shown that the before-sowing treatment of triticale seeds with growth regulators epin and zircon resulted in the increase in the F742/F686 ratio of the stationary fluorescence intensities of the plant leaves at the wavelength bands, 742 and 686 nm, corresponding to the maxima in the leaf fluorescence spectrum. Triticale under the treatment of seeds with growth regulators showed higher chlorophyll content, higher productivity and higher indices of the crop yield.

[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).
