Light Acquisition02:16

Light Acquisition

9.2K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Responses to Heat and Cold Stress02:45

Responses to Heat and Cold Stress

14.5K
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.

Heating and Cooling Curves02:44

Heating and Cooling Curves

26.2K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

Temperature Measurement Sites

2.8K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Adaptations that Reduce Water Loss01:57

Adaptations that Reduce Water Loss

27.7K
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.

Area of Science:

  • Plant physiology
  • Thermal imaging applications
  • Environmental monitoring

Background:

  • Leaf temperature measurement is crucial for understanding plant stress and physiological processes.
  • Laboratory-based thermography is common, but field measurements are limited by sunlight interference.
  • Reflected solar radiation can inaccurately affect direct leaf temperature calculations.

Purpose of the Study:

  • To develop a reliable method for measuring leaf surface temperature under direct sunlight.
  • To overcome inaccuracies caused by reflected radiation in field thermography.
  • To provide practical solutions for accurate plant temperature assessment in natural conditions.

Main Methods:

  • Developed a technique using thermal imagery to generate leaf cooling curves.
  • Calculated the time constant for cooling (τ) from the cooling curves.
  • Extrapolated backwards in time to determine the original sunlit leaf temperature.
  • Compared extrapolated temperatures with direct measurements and temperatures from briefly shaded images.

Main Results:

  • The extrapolated temperature from cooling curves accurately estimated sunlit leaf temperature, especially when specular reflection was minimal.
  • Differences exceeding 2°C were observed between direct measurements and extrapolated temperatures when reflected radiation was high.
  • Temperatures from images taken ~1 second after shading closely matched extrapolated sunlit temperatures.

Conclusions:

  • The developed cooling curve method provides a reliable way to measure leaf temperature in sunlight.
  • Using a brief shaded image (~1 second after shading) is a viable alternative for estimating original sunlit leaf temperature.
  • This technique enhances the applicability of thermal imaging for plant studies under field conditions.
