Water evaporates from plant leaves through minuscule holes called stomata. At a global scale, this process — called transpiration — is a key component of the terrestrial water cycle. When soil is ...

How does water move through plants to get to the top of tall trees? Here we describe the pathways and mechanisms driving water uptake and transport through plants, and causes of flow disruption. Water ...

The aim was to vary the transpiration rate of water culture plants and to measure corresponding values of Δ W, the leaf water potential depression (=DPD=suction force), as well as relative water ...

The influence of soil moisture content and soil water potential on plant water potential, transpiration and net-photosynthesis of potted larch (Larix decidua), spruce (Picea abies) and pine (Pinus ...

The term "corn sweat" refers to water transpiration from corn. Like all plants, corn absorbs water for growth, and then releases excess water through their leaves. With massive plots of corn, like the ...

An e-mail from Clinton wants to know about transpiration. Transpiration is simply a release of water vapor by plants, and it's a big part of the overall water cycle. The water cycle is mother nature's ...

As carbon dioxide levels have risen during the last 150 years, the density of pores that allow plants to breathe has dwindled by 34 percent, restricting the amount of water vapor the plants release to ...

Dear Jessica: Can you please tell me what these droplike things are on the leaves in the picture? If it’s a disease, how do I treat it? — Marilyn Von Braunsberg, Oceanside Dear Marilyn: Those sticky ...

Plant hydraulics drive the biological process that moves fluids from roots to plant stems and leaves, creating streaming electric potential, or voltage, in the process. A study closely examined the ...
