Relationships among Vernalization, Shoot Apex Development and Frost Tolerance in Wheat

Popis výsledku v původním jazyce

The aim of the present study was to learn how saturation of the vernalization requirement and apical development stage are related to frost tolerance in wheat. Mironovskaya 808, a winter variety with a long vernalization requirement, and Leguan, a springvariety without a vernalization requirement, were acclimated at 2°C at different stages of development. Mironovskaya 808 increased its frost tolerance more rapidly; it reached a higher level of tolerance and after a longer duration of acclimation at 2°Cthan was found in Leguan. The frost tolerance of Mironovskaya 808 decreased after saturation of its vernalization requirement, but before its shoot apex had reached the double ridge stage. The frost tolerance of Leguan decreased after the plants had reached the floret initiation stage. The results support the hypothesis that genes for vernalization requirement act as a master switch regulating the duration of low temperature induced frost tolerance.
