transpiration

tran·spi·ra·tion

 (trăn′spə-rā′shən)
n.
The act or process of transpiring, especially through the stomata of plant tissue or the pores of the skin.

tran′spi·ra′tion·al adj.

tran•spi•ra•tion

(ˌtræn spəˈreɪ ʃən)

n.
1. an action or instance of transpiring.
2. the passage of water through a plant from the roots through the vascular system to the atmosphere.
[1545–55; trans- + Latin spīrātiō breathing =spīrā(re) to breathe + -tiōn- -tion]

tran·spi·ra·tion

(trăn′spə-rā′shən)
The process of giving off vapor containing water and waste products, especially through the stomata on leaves or the pores of the skin.
Did You Know? Plants need much more water than animals do. But why? Plants use water not only to carry nutrients throughout their tissues, but also to exchange gases with the air in the process known as transpiration. Air, which contains the carbon dioxide that plant cells need for photosynthesis, enters the plant mainly through the stomata (tiny holes under its leaves). The air travels through tiny spaces in the leaf tissue to the cells that conduct photosynthesis. These cells are coated with a thin layer of water. The cell walls do not permit gases to pass through them, but the carbon dioxide can move across the cell walls by dissolving in the water on their surface. The cells remove the carbon dioxide from the water and use the same water to carry out oxygen, the main waste product of photosynthesis. All this mixing of water and air in transpiration, though, has one drawback: more than 90 percent of the water that a plant's roots suck up is lost by evaporation through the stomata. This is why a plant always needs water and why plants that live in dry climates, such as cacti, have reduced leaf surfaces from which less water can escape.

transpiration

Evaporation of water from leaves.

The presence of water vapour changes the conductivity of the material, and that can be quantified to accurately measure transpiration (the release of water vapour) from a leaf, the researchers found.
According to Asilomar, it will bring promising products currently in development closer to launch and market, as well as commercialise its first compound, an active ingredient that works by increasing a plant's transpiration rate.

Transpiration is less predictable, because it is controlled by the plant's biological processes.
For the understanding about the water relationships of the crop, it is essential to know its physiological responses (stomatal opening, transpiration, accumulation of soluble carbohydrates, production of proline) to the stimuli from the surrounding environment (water in the soil, atmospheric evaporative demand).
Salinity caused a decrease in transpiration and thus gas exchange in quinoa (Sanchez et al.

The trees were prepared for the move by being given treatments to slow their transpiration and movement of hydration (transpiration is the movement of water to the leaves where it evaporates), and then the trees were dug in expertly carved root balls that are proportionate to the size and scale of each tree.
It will help to reduce the amount of water the plant leaves lose through transpiration.
The existence of this variation would infer on changes in transpiration rates, stomatal conductance and photosynthesis as physiological indicators of the presence of stress (LUCENA, 2013); in addition it contributes to the identification and the selection of superior individuals.
Stomatal conductance (gs), net photosynthesis rate (Pn), transpiration rate (Tr), substomatal CO2 concentration (Ci), and water use efficiency (WUE) were measured through three developmental stages including tillering (Til), early grain filling (EGF) and late grain filling (LGF).
