Accessing Chilling Conditions For Perennial Fruit Crop Production in Kentucky
… plants, require cool winter temperatures (chilling hours) to ensure leaf and flower bud production in the following season. Temperate Regions are characterized by variable winter and spring temperatures. Failure of meeting sufficient chilling requirement results in deformed fruits, unequal …

Chilling injury and the control thereof in selected Leucadendron cultivars
… compromise as long-term cold storage can lead to chilling injury in susceptible ornamental Cape Flora species, selections, and cultivars. The development of chilling injury symptoms has a detrimental impact on the commercial value of the Cape Flora stems, rendering them unmarketable. A study was …

Stomatal and nonstomatal responses of photosynthesis to water deficits and chilling
… to photosynthesis to water deficits and chilling. Photophosphorylation was studied as a potential limitation since its fragile and highly integrated nature makes it a prime candidate for disruption by unfavorable environmental conditions and because it had been implicated in earlier in …

The effect of dark chilling on circadian-regulated enzyme activities in tomato
… treatment inhibits next day photosynthesis in chilling-sensitive plant species such as tomato and cucumber. In tomato, net photosynthesis is reduced 60% by an overnight chill at 4$\sp\circ$C. The mechanism for the inhibition of photosynthesis is unknown. However, one effect of the low …

Influence of iron and cytokinin on Cynodon spp. cultured at chilling temperatures
… and nonstructural carbohydrate composition to chilling temperatures was also studied. Foliar applications of Fe in late-summer and fall extended bermudagrass performance during low temperature periods of fall. Frequent Fe applications aided the retention of green bermudagrass turf during …

Thioredoxin-mediated reduction of photosynthetic carbon reduction enzymes following chilling in the light
… was effectively reduced by thioredoxin. The chilling treatment had no effect on the midpoint potential of the regulatory sulfhydryl groups ($-$310 mV), indicating no direct chilling damage to the enzyme. Thiol labeling of FBPase in vivo showed that there was a 60% decrease in sulfhydryl …

Improving C4 photosynthetic chilling tolerance in bioenergy crops: the search for elite breeding materials
… due to photosynthetic limitations at chilling temperatures (<20° C). The mechanistic limitation at chilling temperatures has been suggested to be caused by the chilling-induced lability of pyruvate phosphate dikinase (PPDK) and decrease in ribulose-1,5-bisphosphate …

Physiological and nutritional changes in nitrogen fixing trees associated with autumnal senescence and chilling
In the first of two studies, autumnal leaf senescence of four temperate woody deciduous plants, autumn olive (Elaeagnus umbellata Thunb.), black locust (Robinia pseudoacadia L.), American sycamore (Platanus occidentalis L.) and honey locust (Gleditsia triacanthos L.), was studied during the autumns …

Feasibility of spray chilling encapsulation for protection and stabilization of flavor compound-zinc ion complexes
… investigate the feasibility of utilizing spray chilling encapsulation technology to protect the flavor compound-zinc ion complex, 2-acetylpyridine-ZnCl2 (2-APri-ZnCl2). 2-APri-ZnCl2 was loaded at 5% (w/w) in molten Hydro-KoteC®, a commercial vegetable stearin. Spray chilling of this suspension …

Determination of decomposition rates in selected mid-Atlantic fish species stored under iced and super-chilling temperatures
Three different species of fish (sea trout, Spanish mackerel and catfish) were studied. Samples undergoing normal spoilage were compared with samples which had undergone a sanitizing treatment with alcohol. Differential temperature storage studies were conducted at 290 °F (-1.7 °C) and 32 °F (0 …

High Light and Low Temperature Effect on D1 Synthesis and Turnover in the Chilling Sensitive Plant Lycopersicun Esculentum
… light is combined with low temperature. In the chilling sensitive plant tomato (Lycopersicun esculentum var. Mill Floramerica), these combined stresses were found to cause a decrease in de novo synthesis of D1, a component of photosystem II (PSII) reaction center which is known to be damaged by …

Understanding the physiological and molecular basis of chilling tolerance across species of the C4 genera Miscanthus and Spartina
… giganteus has been found to possess significant chilling tolerance relative to other C4 species. This dissertation aims to understand this apparently unique tolerance of C4 photosynthesis with three investigations (Chapters 2-4). Chapter 2 analyses the transcriptome of M. × giganteus on …

Effect of chilling, hydrogen cyanamide, hot water and bud scale removal on bud break of 'Tifblue' rabbiteye blueberry
… in warm areas. The delay is due to a lack of the chilling which is required to break bud endodormancy. Bud endodormancy can be overcome in some species by treatments such as H<sub>2</sub>CN<sub>2</sub>, heat, and bud scale removal. We tested the effects of chilling, H<sub>2</sub>CN<sub>2</sub>, …

The effect of low temperature on the circadian expression of nuclear genes encoding chloroplast proteins in chilling sensitive plants
… the inhibition in photosynthesis caused by dark-chilling in tomato.

Using Plant Growth Regulators to Improve the Quality of Containerized Herbaceous Peony
… as well as for cut flowers. Peonies require a chilling period to break dormancy but not for flower bud differentiation. For all studies discussed in this dissertation, two peony cultivars, Sarah Bernhardt and Inspecteur Lavergne, small (3–5 eye) crowns from Holland were potted in 3.8-L pots in …

IDENTIFICATION OF ULTRASTRUCTURAL AND BIOCHEMICAL MARKERS OF FROST AVOIDANCE IN THE CUTICULAR LAYER OF CORN
… expansion. While many studies have examined corn chilling and frost sensitivity, the impact of simulated autumn temperatures (termed chilling pre-treatment) preceding a frost has not been reported. The effect of chilling pre-treatment, on subsequent freezing avoidance was studied in mature hybrid …

The Influence of Chilling and Heat Accumulation on Bloom Timing, Bloom Length and Crop Yield in Almonds (Prunus dulcis (Mill.))
… and pollination. The practice of monitoring chilling and heat accumulation will allow growers to anticipate bloom, prepare to optimize bee activity during bloom, and plan for possible crop yield variations due to adverse weather conditions during bloom in almonds.</p>
