Is there any way of measuring transpiration rate without using a potometer? I am investigating the relationship between leaf area and transpiration rate. Can you suggest how I can change the area of a leaf?;

Transpiration is the evaporation of water into the atmosphere from the leaves and stems of plants. Plants absorb soilwater through their roots and this water can originate from deep in the soil.

To clarify mechanisms underlying variation in transpiration rate among deciduous broad-leaved tree species, we measured diurnal changes in stomatal conductance (gs) and leaf water potential, and calculated the maximum transpiration rate (Emax), leaf-specific hydraulic conductance (K(s-l)) and difference between the soil ...

This study focuses on the spatial patterns of transpiration-driven water isotope enrichment (Delta(lw)) along monocot leaves. ... The model reproduces well all published measurements of Delta(lw) along monocot leaf blades, except at the leaf tip and given the uncertainties on measurements and model parameters. We show that...

This study focuses on the spatial patterns of transpiration-driven water isotope enrichment (Δlw) along monocot leaves. ... It has been suggested that these spatial patterns are the result of competing effects of advection and (back-)diffusion of water isotopes along leaf veins and in the mesophyll, but also reflect...

An approximately inverse linear relation between transpiration rate and logarithm of resistance to viscous flow through the leaf is believed to be the resultant of an inverse curvilinear relationship between the diffusive conductance of the stomata and log.
