Seedlings of Leptospermum scoparium J.R. et G. Forst (manuka) originating from seed from a low altitude coastal site (Auckland) and from a high altitude inland site (Desert Road) were grown for 96 days in four controlled environments to compare the relationship between growth temperature and frost hardening. Day/night temperature treatments were 12/6, 12/3, 12/0 and 12/-3 degrees C. Frost hardi...

Frost stress is one of the abiotic stresses that causes a significant reduction in winter faba bean yield in Europe. The main objective of this work is to genetically improve frost tolerance in winter faba bean by identifying and validating QTL associated with frost tolerance to be used in marker-assisted selection (MAS). Two different genetic backgrounds were used: a biparental population (BPP...

abstract the present research was done to evaluate proline, proteins and sugars of flower buds of pistachio trees during phonological stages. this study was conducted using a split-plot design with three replications considered time as main factor (5 stages) and cultivars (ahmad-aghaee, ouhadi, kaleh-ghochi and akbari) as secondary factor. the experiment was conducted at ferdowsi university of ...

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...

Rising temperatures due to climate change can significantly impact the freeze–thaw condition of airport pavements in cold regions. This case study investigates implications warming on penetration and frost heave critical airports across Canada. To this end, different methods were used quantification process through simulations considering emission scenario RCP8.5 20 40 year time horizons. The r...
