Effects of Vernalization Duration, Light Intensity during Vernalization and Low Temperature Holding after Vernalization on Flowering of Nobile Dendrobium Hybrids
… three nobile dendrobium hybrids in relation to vernalization duration and light intensity during vernalization were studied in the first experiment. Mature Dendrobium Red Emperor 'Prince', Dendrobium Sea Mary 'Snow King', and Dendrobium Love Memory 'Fizz' were cooled at 10 degrees C with 300 to …

Predicting the impact of climate change on vernalization for Arabidopsis thaliana
… require a prolonged period of cold, known as vernalization, to ensure prompt floral transition occurs in spring. This thesis addresses the question of whether partial saturation of cold requirements might delay flowering under future climate scenarios. Laboratory experiments set up to …

Examining Hessian fly (Mayetiola destructor) management concepts and quantifying the physiological impact of hessian fly feeding on post-vernalization selected cultivars of winter wheat in Kansas
… are still providing protection after winter vernalization. Greenhouse trials indicated that ‘Armour’, a cultivar considered intermediately resistant, remains resistant under infestation levels of 1 fly/tiller but significant seed weight losses occured under infestations of 3 flies/tiller. In …

Phenology, canopy development, biomass and grain yield of annual canarygrass (Phalaris canariensis L.)
… a cultivar each of a spring wheat with minimum vernalization requirement and an oat cultivar sown at different dates (SDs). Young seedlings were then exposed to vernalizing treatments of 5, 10 and 15°C for 0, 2, 7, 14 and 21 days in controlled-environment experiments. Canaryseed cultivars …

Dissecting Earliness per se and Photoperiod heading date effects in bread wheat (Triticum aestivum)
Vernalization, photoperiod and the poorly defined earliness per se (Eps) genes regulate flowering in plants. This thesis used elite hexaploid wheat varieties and focused on an Eps QTL on 1DL, and photoperiod QTLs on 1BL and 5AL short day QTL using doubled haploid (DH) populations. Four independent …

Evaluation of Genomic Prediction and the Agronomic Performance of Facultative Barley
… 4H were identified, correlating with the vernalization gene "VRN-H2." Several haplotypes found on chromosome 4H within appear significant and may contribute to differences in facultative habit. Only 28% of facultative lines could be accurately predicted based on genetic data, suggesting …

Genetic diversity of the HvFT1 flowering gene in Nordic spring barley (Hordeum vulgare L.)
… as a central integrator for signals of the vernalization, photoperiod and circadian clock pathways and promotes flowering. This is of interest for barley breeders on Iceland, who aim to produce early maturing cultivars. The main objective of this project is to study the genetic diversity of …

Nitrate: metabolism and development
… signalling pathways for photoperiod, autonomy, vernalization and gibberellic acid. Global analyses of gene expression of two independent flowering systems, a light impaired mutant (co2tt4) and a constitutive over-expresser of the potent repressor of flowering (35S::FLC), were to be investigated …

FUNCTIONAL ANALYSIS OF TRANSCRIPTION FACTORS INVOLVED IN REPRODUCTIVE MERISTEM IDENTITY IN ARABIDOPSIS THALIANA
… pathways that control flowering (photoperiod, vernalization, autonomous and gibberellin pathways), giving rise to the activation of the floral meristem identity genes (Parcy, 2005). In chapter 2, , we show that AGAMOUS-LIKE 42 (AGL42), AGAMOUS-LIKE 71 (AGL71) and AGAMOUS-LIKE 72 (AGL72) that …
