What Is Transpiration-Page 3
transpiration in a 12ha forest patch in Ban Tat hamlet, Hoa Binh, Vietnam. The objectives of this study were to determine: (1) the effects of adjacent clearings on the microclimate of a small forest patch, (2) the ex-tent to which transpiration by trees is dependent on distance from the edge of the patch, (3) whether tran-
Since, transpiration takes place through stomata which are normally located on the ventral side of the leaf this reduction in temperature is , more experienced beneath the crowns of the trees. Water is transported from roots to leaves through vascular tissue termed as xylem. There are several theories of transpiration such as water potential .
thewoodland's transpiration with only 11% of its sapwood area. The difference in transpiration influenced water table depths, which were 2 m in the savanna and 6.5 m in the woodland. Regionally, row-crop agriculture has increased groundwater recharge and raised water tables, providing surplus water that perhaps facilitated elm encroachment.
13 Transpiration by trees can be the major pathway for discharge of water from 14 woodlands and consequently determines the hydrological balance of woodlands, exceeding 15 transpiration by grasses and shrubs (Dragoni et al. 2009; Eamus et al. 2006b; Zeppel and 16 Eamus 2008). Spatial and temporal variation in tree water-use and differences .
decrease their transpiration and therefore cooling effect. A simple estimation of available rainwater, based on widely available data, explained 68% of variance in stomatal conductance Night-time transpiration was active in all studied trees and reached on average 7% and 20% of daytime E L of sunlit and shaded leaves, respectively, with an
groundwater contributions to tree transpiration. We provide evidence on the tree unrestricted access to groundwater solely based on meteorological, stem sap flow and leaf water potential data. Using a soil mass balance approach, we estimated the yearly soil and groundwater contributions to tree transpiration: 69.7% and 30.3%, respectively.
transpiration rates under different conditions of light, humidity, temperature, and air movement. The data will be collected by measuring pressure changes as the plant takes up water into the stem. OBJECTIVES In this experiment, you will Observe how transpiration relates to the overall process of water transport in plants.
Elapsed time analysis: The effect of temperature on PN, E, WUE, and transpiration coefficient (TC H2O/CO2 1/WUE) was analyzed as a function of elapsed time throughout a 24-h period. The average value from four replications of these processes was plotted as a function of time in order to demonstrate the differences between

Transpiration (the evaporation of water from the leaves) is the major factor that pulls the water up through the plant. It is important to recognize that this upward conducting tissue is continuous through vascular (tracheophyte) plants, starting at the roots and continuing upward through the plant to the leaves.
Transpiration measurements were made from 6 to 27 August (Day 218-Day 239) 1994 at the National Soil Dynamics Laboratory (32.6"N, 85S"W), Auburn, AL, USA. The soil at the study site is a Blanton loamy sand topsoil (loamy, siliceous, thermic Grossarenic Paleudult). Plants were continuously exposed to ambient or elevated [CO,] .
Transpiration is the passage of water vapor through plant pores into the atmosphere. Evapotranspiration is the combination of evaporation and transpiration that is often referred to as crop water use or crop ET.
