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 ...
Plant stomata are pores in the epidermis of plant leaves. They play a key role in regulating the gas-water exchange between the plant and the atmosphere, which enables photosynthesis and transpiration ...
Abscisic acid (ABA) prevents opening of closed stomata and causes open stomata to close. A dual-source model is proposed linking ABA to diurnal stomatal movements. Darkness would favour guard cell ...
TWO paper by Sir Francis Darwin (Proceedings of the Royal Society, B, vol. Ixxxvii.) mark an important advance in the study of the process of transpiration in plants. Hitherto, although transpiration ...
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 ...
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 ...
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 ...
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 ...
