Abstract

The influence of cold acclimation and deacclimation on the synthesis of dehydrins in leaves and crown of two variety of winter wheat (Triticum aestivum L.) that are differed in frost resistance was studied. It is detected that the varieties of winter wheat «Irkutskaya» and «Pamyat’» are differed in the dynamics of accumulation and content of dehydrins in leaves and crown after different stages of acclimation and deacclimation. The increased frost resistance of winter wheat of the variety «Irkutskaya», is due to able to overwinter in the conditions of the sharply continental climate of Eastern Siberia, is characterized by a higher content of dehydrines in the crown during acclimation and deacclimation, compared with the less resistant variety «Pamyat’». More attention is required to study the mechanism of synthesis of dehydrins at the initial stage of deacclimation in less cold-resistant varieties.

The reported study was funded by RFBR № 17-54-04076 and BRFFR № Б17РМ-054.
