  2. Transpiration - Wikipedia

    en.wikipedia.org/wiki/Transpiration

    Transpiration rates of plants can be measured by a number of techniques, including potometers, lysimeters, porometers, photosynthesis systems and thermometric sap flow sensors. Isotope measurements indicate transpiration is the larger component of evapotranspiration . [ 11 ]

  3. Evapotranspiration - Wikipedia

    en.wikipedia.org/wiki/Evapotranspiration

    Transpiration: the movement of water from root systems, through a plant, and exit into the air as water vapor. This exit occurs through stomata in the plant. Rate of transpiration can be influenced by factors including plant type, soil type, weather conditions and water content, and also cultivation practices. [ 6 ] :

  4. Transpirational cooling (biological) - Wikipedia

    en.wikipedia.org/wiki/Transpirational_cooling...

    Transpirational cooling is the cooling provided as plants transpire water. Excess heat generated from solar radiation is damaging to plant cells and thermal injury occurs during drought or when there is rapid transpiration which produces wilting. [1]

  5. Guttation - Wikipedia

    en.wikipedia.org/wiki/Guttation

    At night, transpiration usually does not occur, because most plants have their stomata closed. When there is a high soil moisture level, water will enter plant roots, because the water potential of the roots is lower than in the soil solution. The water will accumulate in the plant, creating a slight root pressure.

  6. Transpiration stream - Wikipedia

    en.wikipedia.org/wiki/Transpiration_stream

    Overview of transpiration. 1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

  7. Soil moisture - Wikipedia

    en.wikipedia.org/wiki/Soil_moisture

    Transpiration plus evaporative soil moisture loss is called evapotranspiration. Evapotranspiration plus water held in the plant totals to consumptive use, which is nearly identical to evapotranspiration. [72] [74] The total water used in an agricultural field includes surface runoff, drainage and consumptive use.

  8. Water-use efficiency - Wikipedia

    en.wikipedia.org/wiki/Water-use_efficiency

    However, there is some question as to the benefit of increased water-use efficiency of plants in agricultural systems, as the processes of increased yield production and decreased water loss due to transpiration (that is, the main driver of increases in water-use efficiency) are fundamentally opposed.

  9. Xerophyte - Wikipedia

    en.wikipedia.org/wiki/Xerophyte

    Plants absorb water from the soil, which then evaporates from their shoots and leaves; this process is known as transpiration.If placed in a dry environment, a typical mesophytic plant would evaporate water faster than the rate of water uptake from the soil, leading to wilting and even death.
