Internal frost damage in concrete - experimental studies of destruction mechanisms
… was to identify mechanisms acting at internal frost destruction of concrete. By 'internal frost destruction' is meant damage caused inside concrete that is moisture insulated from the surroundings, i.e. when no moisture exchange with the surroundings is possible during freeze-thaw. Thus, the …

Survival of ice nucleation-active and genetically engineered inactive strains of Pseudomonas syringae
… in the 18 hours after oat plants incurred frost damage at {dollar}-{dollar}5 and {dollar}-{dollar}12{dollar}\sp\circ{dollar}C. Plants colonized by the non-INA strain were undamaged at {dollar}-{dollar}5{dollar}\sp\circ{dollar}C and exhibited no changes in population size. As temperatures …

Vitality studies on frozen wheat
Three times in the past three decades frost has caused exceptionally severe crop damage in Western Canada. Although early autunm frosts are a recurring hazard, damage usually is scattered and light, often being confined to the more northerly areas. It has been estimated that one-half of the grain …

Regrowth analysis of alfalfa (Medicago sativa, L.) during three seasons in 1966
… production of new leaves because of weevil and frost damage. The greatest efficiency in L.A.I. occurred during early summer and the lowest in late summer; the same trend was observed in N.A.R. Interception of 95% of the light required different L.A.I. values during the three seasons, and these …

Spatiotemporal Dynamics of Snow-Free Frost Exposure in the Western Cordillera Seasonal Snow Zones
… the ground surface becomes more vulnerable to frost damage during synoptic-scale cold events, such as arctic air incursions, even as average temperatures rise. The net impact of these competing effects on ground-level frost exposure remains poorly understood. This thesis addresses this gap by …

Limitations of savanna trees in the highveld grasslands of South Africa
… be able to escape frequent fires. Alternatively, frost may exclude trees from grasslands. A seedling transplant experiment of savanna tree species of the Acacia genus, into grassland and savanna areas arranged across an altitudinal gradient, was used to compare growth in these varying climates …

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 …

IDENTIFICATION OF ULTRASTRUCTURAL AND BIOCHEMICAL MARKERS OF FROST AVOIDANCE IN THE CUTICULAR LAYER OF CORN
… as a highly economically important yet, frost sensitive crop. Climate change trends are show increased frost damage. The global need for food production is increasing and current production will not meet demand. Corn is killed at the moment of freezing and therefore, developing frost …

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 …
