GENOMIC TOOLS TO IMPROVE PEACH (P. PERSICA L. BATSCH) RESILIENCE TO CLIMATE CHALLENGES
… the dormant period in order to avoid spring frost and to select the appropriate cultivar to be grown in a certain environment. Nowadays, renewed interest is rising in this topic in light of projected changes in thermal availability and distribution during winter season that may affect fruit …

Exploiting the Productivity of C4 Photosynthesis in Cool Temperate Climates: Mechanisms and Thresholds of Cold Tolerance in Miscanthus, Saccharum, and Spartina pectinata
… produce leaves that tolerate spring chilling and frosts to harness the long photoperiods. Although there is nothing inherently cold sensitive about the C4 pathway, cold tolerant C4 grasses are rare and the additional C4 cycle and architecture introduce more potentially cold sensitive sites. In …

Systems-Level Analysis of Rootstock–Scion Interactions in Apple Reveals Mechanisms of Cold Tolerance Under Field Frost Events
Late spring frosts threaten apple (Malus × domestica Borkh.) productivity by damaging developing floral buds, yet the mechanisms underlying rootstock-dependent cold tolerance in orchard conditions remain poorly understood. In this study, we investigated frost tolerance in two apple (Malus domestica …

Characterizing phenotypic diversity, genotype by environment interactions, and optimizing selection efficiency of a miscanthus germplasm collection
… yield-component traits, and spring and autumn frost tolerance, 4) determine the predictive value of three putative yield-component traits for estimating yield, and 5) quantify the relative importance of genotype × environment and error variances for estimating genotypic values. We found that …

Plant growth responses to winter climate change: from amongand within-species variation to plant-soil interactions
… acclimation and deacclimation, dormancy loss and frost tolerance. Amongspecies variation was then compared with within-species variation to determine if a species could be largely treated as a single response unit under different climatic extremes. Plant-soil interactions were also explored to …

Improving C4 photosynthetic chilling tolerance in bioenergy crops: the search for elite breeding materials
… to its high biomass yields and photosynthetic tolerance of mild chilling temperatures (15-20° C). However, Miscanthus x giganteus lacks tolerance of severe chilling conditions (0–12° C) and overnight frosts associated with early-season days in high latitudes. In chapter 2, two species from the …

MEASURING AND MODELLING COVER CROP GROWTH AND AGRONOMIC EFFECTS
… of the following year. When sown in autumn, frost-sensitive cover crops may also be terminated efficiently by frost damage: this termination method is frequently called ‘winterkill’. Black oat (Avena strigosa Schreb.) and white mustard (Sinapis alba L.) are two of the most interesting and …
