What Is Transpiration-Page 4
Transpiration response to vapor pressure deficit Three sets of experiments were performed to measure the response of the eight quinoa genotypes to a range of VPD levels (Table1). Plants were grown in a growth chamber located in the North Carolina State University Phytotron. The first set, which included three genotypes, was sown on 24 .
transpiration rates of different trees are largely influenced by LAI [3]. Transpiration is also influenced by an increase in stem diameter at DBH and root growth [3]. The ability of plants to acquire water depends on root distribution [28] which also depends on the above ground responses of plants such as leaf area and leaf biomass [24].
transpiration at this site, whereas midstory and suppressed trees contributed 18 and 5%, respectively. After accounting for vapour pressure deficit and solar radiation, leaf wetness was a significant driver of sap flux, reducing it by as much as 28%.
29 What is a description of transpiration? A exchange of gases between the leaf and the atmosphere B loss of water vapour from the leaves and stems of a plant
Thermal transpiration is the Macroscopic movement of particles due only to an imposed Temperature Gradient. Objective: Measure the Mass Flow Rate along a tube induced

thesis and transpiration, thereby coupling the carbon and water cycles and affecting surface-atmosphere energy ex-change. The environmental response of stomatal conduc-tance has been measured mainly on the leaf scale, and theo-retical canopy models are relied on to upscale stomatal con-ductance for application in terrestrial ecosystem models and
2) Rainfall is lost through various processes such as Evaporation, Transpiration, Interception, Depression Storage & infiltration. 3) Interception is the process of interrupting the movement of water. It can take place by vegetal cover or depression storage in puddles and in land formations such as rills and furrows.
transpiration cooling system under study and so as to thermally connect the cooling system to the structural network. CTC input flight history is May - June 1972 user-specified in terms of (a) local flow conditions versus Mach number, (b) Mach number and alti tude versus time, and (c) atmospheric properties .
Transpiration ratio is a measurement of plant water-use effi-ciency that has been employed since early research on the topic ( Woodward 1699 , Lawes 1850, Briggs and Shantz 1914 , Shantz and Piemeisel 1927 ). It describes the rate of water loss from a plant for a given amount of dry matter production.
During transpiration, water evaporating from the spaces within leaves escapes through small pores called stomata. Although evaporation of water through open stomata is a major route of water loss in plants, the stomata must open to allow for the entry of CO 2 used in photosynthesis. In addition, O
Transpiration is the loss of water from the leaves of plants. Stomates are tiny pores on the surface of leaves that allow for the passage of oxygen and carbon dioxide during photosynthesis.
