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 ...

A tiny, little-understood plant pore has enormous implications for weather forecasting, climate change, agriculture, hydrology, and more. Scientists have now overturned the conventional belief about ...

New research on how microscopic leaf pores respond to sunlight reveals some of the first universal relationships between plants and climate. Understanding these relationships could vastly improve ...

Stomata – the tiny pores through which plants take in carbon dioxide and give off oxygen and water – are closing up everywhere on earth as atmospheric CO2 levels rise. This change in plant structure ...

Most of the water that enters a plant will exit the leaf into the atmosphere. This provides a continuous stream of water which is known as the transpiration stream. Surface area (not an environmental ...

An experimental procedure is described by which contemporaneous assessments of leaf resistance, rates of transpiration and of carbon dioxide exchange can be made on attached leaves. The relative ...

Particulate matter deposits on leaves increase plant transpiration and the risk of plants suffering from drought. Particulate matter could thus be contributing more strongly to tree mortality and ...

Scientists have discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism - tiny pores known as ...

BLOOMINGTON, Ind. -- 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 ...

There may be variation in the decrease in mass of different leaves. It is important to repeat the experiment and calculate a mean for each set of data. To be representative of the whole leaf, the ...

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 ...
