American Journal of Botany, Vol. 28, No. 8 (Oct., 1941), pp. 722-725 (4 pages) In the leaf blades stomatal frequency was the highest near the apex and lowest near the midrib, and in the different ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Scientists 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 'stomata' ...
