What Is Transpiration-Free documents Library

Transpiration occurs through young or mature stem is called as Cauline transpiration. Depending upon the plant surface, transpiration is classified into three types: Water vapour diffuses out through minute pore (stomata) present in soft aerial part of plant is known as Stomatal Transpiration Stomatal Transpiration

Transpiration Rates Transpiration depends on concentration gradients in the same way that mass flow does The driving force of transpiration is the "vapor pressure gradient." This is the difference in vapor pressure between the internal spaces in the leaf and the atmosphere around the leaf Factors affecting rate of transpiration

Transpiration Pull This is the main force that causes water to move up the stem against the force of gravity. Transpiration is the loss of water in the form of water vapour through the aerial parts of a plant through stomata Experiment to demonstrate that transpiration occurs through the aerial parts of a plant

Global Reference Evapo-Transpiration (Global-ET0) Potential Evapo-Transpiration (PET) is a measure of the ability of the atmosphere to remove water through Evapo-Transpiration (ET) processes. Among several equations to estimate PET, a FAO application of the Penman-Monteith equation (Allen et al. 1998), here referred as FAO-

transpiration rates increase in response to rainfall events, allowing higher transpiration rates than the level that is expected to be achieved under isohydric stomatal control (Oren et al., 1999). In this study, we monitored the sap flux of P.pallida stands with ample access to shallow groundwater and compared the annual transpiration rate .

schemes such as film and transpiration cooling will have to be utilized. Theoretically transpiration cooling is superior to film cooling as shown in reference 4, provided the oxidation problems described below can be over- come. Also good creep life can be accomplished with transpiration cooled blade

transpiration; thus interception generally precipitates closer to its evaporative source than transpiration, which is particularly pronounced outside the tropics. We conclude that interception mainly works as an intensifier of the local hydrological cycle during wet spells and wet seasons. On the other hand, transpiration remains active

The total number of stomata varies by species. Since transpiration occurs via the stomata, this value is an important con-sideration when determining the transpiration rate. 10. The rate of transpiration for a plant is generally reported as volume of water (in milliliters) or the mass of water (in grams) per square meter of leaf area.

transpiration rate was higher in HP than that in SDJ. Considering higher CO 2 exchange rate together with lower transpiration in SDJ indicated that some other cultivars rice genetic resources could use to enhance rice yield potential and water use efficiency in an irrigated rice system.

Transpiration is called a necessary evil. It means that transpiration is a potentially harmful process but is unavoidable too. Transpiration may be a harmful process in the sense that during the conditions of drought, loss of water from plant results in serious desiccation, wilting and often death. On the other hand, transpiration is necessary too.
