Our approach is predicated on the knowledge that precipitation δ 2 H and δ 18 O values (see Methods for definitions) co-vary along a regression line with a δ 2 H/δ 18 O slope of eight (this is the ...

Everyone knows that trees combat climate change by absorbing carbon dioxide out of the air. Now, plant leaves are tackling global warming in another way — by serving as models for a technology that ...

Cornell University researchers have created the world's first synthetic tree. So far, it's a very small 'tree' which stands in a palm-sized piece of hydrogel. This 'tree simulates the process of ...

LOUISVILLE, Ky. (WAVE) - Evapotranspiration is responsible for 15% of our atmosphere's water vapor. Evapotranspiration is the combination of evaporation and transpiration. Both processes release water ...

The exact science of tree sap transport has puzzled plant physiologists for many years. Sap's migration throughout tree trunks and branches is linked heavily to transpiration, the movement and ...

The effect of nitrogen supply on the transpiration rate and stomatal opening of potted bean plants was studied in a series of experiments. The transpiration rates of N-supplied plants were higher than ...

As temperatures rise in July and August, transpiration from plants might add to the humidity. One plant that gets more blame than others is corn, said Dan Quinn, assistant professor of agronomy and ...

As water travels through the xylem in the stem and leaf, it is being replaced by water taken up by the roots. Photosynthesis produces glucose in the green parts of plants, which are often leaves. This ...
