Sentences with phrase «plant transpiration»
Plant transpiration refers to the process by which plants release water vapor into the atmosphere through tiny pores on their leaves, called stomata. It is similar to humans sweating, but plants do it to cool themselves down and to transport nutrients from the roots to other parts of the plant. Full definition
The study accounted for evapotranspiration, which is water released into the air through plant transpiration and soil evaporation, as well as precipitation, and surface water flowing into and out of the Central Valley.

In the study, published in the Proceedings of the National Academy of Sciences (PNAS), the researchers found that these indirect effects explain, on average, 28 per cent of the total plant productivity response, and are almost equal to the size of direct effects on evapotranspiration (ET)-- the sum of evaporation and plant transpiration from the land to the atmosphere..
Currently, there are three major hypotheses explaining this nutrient enrichment: nutrient enrichment via plant transpiration; bird guano as birds nest in the islands; and pre-Columbian human occupation,» said Cooper Fellow and Professor of Biology Leonel Sternberg.
(Evapotranspiration is the process by which water is transferred from soil and groundwater to the atmosphere through plant transpiration — loss of water through foliage — and soil evaporation.)
Rising CO2 levels affect a lot of plants directly by stimulating photosynthesis and reducing the loss of water (plant transpiration) by reducing the opening of the small pores in the leaves, known as «stomata».
Continuously monitoring plant «water stress» is particularly critical in arid regions and traditionally has been done by measuring soil moisture content or developing evapotranspiration models that calculate the sum of ground surface evaporation and plant transpiration.
Soil moisture is a key variable in controlling the exchange of water and heat energy between the land surface and the atmosphere through evaporation and plant transpiration.
