Abstract:
The effect of co-activation of
the stress-memory formation potential under
repeated drought of Glycine max (Merr.) L.
plants was recorded using cytokinin (CK),
thiourea (TH) and, especially, complex
preparation Polyel. Glycine max plants
(Merr.) L. of Moldovitsa, Nadejda and
Magia varieties, exposed to two cycles of
"drought–rehydration" at the "first trifoliate
leaf" and "flowering - pods formation”
phases served as test subjects. The toleranceinducing
effect manifests itself by
maintaining the content of assimilatory
pigments, photosynthesis and growth
processes at a significantly higher level.
After the restoration of the optimal moisture
background, plants pre-treated with CK, TH
and the preparation Polyel, which endured
moderate stress in the initial stages of
ontogenesis, had restored functional
processes. The information obtained in this
work certainly opens the management
perspective of the ability to form stress
memory, adaptation and tolerance of plants
to the unfavourable fluctuation of humidity
and recurrent drought. The management
possibilities of plant adaptation and tolerance
are discussed.
