Frost Resistant Concrete01:29

Frost Resistant Concrete

335
Concrete's susceptibility to frost damage during freeze-thaw cycles demands strategic measures to enhance its frost resistance. Employing techniques like air entrainment, adjusting the water-cement ratio, proper curing, and selecting appropriate aggregates are essential.
Introducing microscopic air bubbles into the concrete mix through air entrainment creates small voids that accommodate ice expansion, thereby reducing internal pressures and preventing cracking. The optimal amount of...

Responses to Heat and Cold Stress

14.6K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Frost Action on Concrete01:27

Frost Action on Concrete

357
Concrete structures in cold climates, such as those along roadsides, can retain moisture. This moisture makes them susceptible to frost-related damage when temperatures fall below freezing. Adding moisture worsens the damage during temperature fluctuations, leading to repeated freezing and thawing. De-icing salts, spread over these structures to melt ice, add to the freeze-thaw cycle, and draw even more moisture into the concrete.
This freeze-thaw cycle primarily causes surface scaling, where...

Adaptations that Reduce Water Loss01:57

Adaptations that Reduce Water Loss

27.8K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Regulation of Transpiration by Stomata02:04

Regulation of Transpiration by Stomata

30.7K
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Area of Science:

  • Plant physiology and molecular biology
  • Horticultural science and climate change adaptation

Background:

  • Spring frosts pose a significant threat to sustainable fruit production in temperate and boreal regions.
  • Climate change is exacerbating frost damage risks and economic losses in fruit cultivation.
  • Ethephon, an ethylene-based compound, delays blooming to mitigate frost damage but has harmful side effects.

Purpose of the Study:

  • To review the current understanding of ethylene's role in modulating bud dormancy and bloom time in fruit trees.
  • To explore the molecular mechanisms underlying ethylene-mediated bloom delay for improved frost protection strategies.
  • To identify potential pathways for future research into dormancy regulation and frost damage alleviation.

Main Methods:

  • Review of existing scientific literature on ethylene, bud dormancy, and blooming in deciduous woody perennials.
  • Analysis of recent advances in omics (genomics, transcriptomics, etc.) and bioinformatics.
  • Synthesis of current knowledge on ethylene's interaction with other molecular networks.

Main Results:

  • Ethylene plays a crucial role in regulating bud dormancy and bloom phenology in temperate fruit trees.
  • Limited research exists on the precise molecular mechanisms of ethylene-mediated bloom delay.
  • Omics and bioinformatics offer powerful tools to investigate these complex pathways.

Conclusions:

  • Further research into ethylene's molecular interactions is essential for developing effective, non-harmful frost protection methods.
  • Understanding dormancy regulation can lead to innovative strategies for mitigating climate change impacts on fruit production.
  • This review provides a framework for future studies on ethylene signaling and its application in horticulture.
