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

Relationships among vernalization, shoot apex development and frost tolerance in wheat.

BACKGROUND AND AIMS Frost tolerance of wheat depends primarily upon a strong vernalization requirement, delaying the transition to the reproductive phase. 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. METHODS 'Mironovskaya 808', a winter variety with a long vernalization requireme...

the relationships among the vernalization response, carbohydrate accumulation, developmental stages and frost tolerance in bread wheat cultivars

frost tolerance of winter wheat depends primarily on a strong vernalization requirement, delaying the transition to reproductive phase. the responses of four bread wheat cultivars (triticum aestivum l.) to low-temperatures were examined in controlled environment and field conditions. prolonged cold treatment accelerated the transition to reproductive development in winter wheats (cv. norstar an...

Exogenous application of molybdenum affects the expression of CBF14 and the development of frost tolerance in wheat.

Wheat is able to cold acclimate in response to low temperatures and thereby increase its frost tolerance and the extent of this acclimation is greater in winter genotypes compared to spring genotypes. Such up-regulation of frost tolerance is controlled by Cbf transcription factors. Molybdenum (Mo) application has been shown to enhance frost tolerance of wheat and this study aimed to investigate...
