leaf_specific_hydraulic_conductivity

Label: Leaf specific hydraulic conductivity (Kl)
Entity URI: https://w3id.org/APD/traits/trait_0021018
Type: numeric
Definition: A stem [PO:0009047] water transport [GO:0006833] trait which is a measure of the rate [PATO:0000161] of water [CHEBI:15377] movement [NCIT:C37994] through a stem under a specific [NCIT:C38024] driving force [PATO:0001035] (water potential [EnvThes:22311] gradient [NCIT:C70693]), normalised to the branches' leaf [PO:0025034] area [PATO:0001323] and accounting for the path (stem) length [PATO:0000122]. It is calculated as the ratio of the water flow rate (kg/s) to the water potential gradient across the stem segment (MPa), divided by the total leaf area (1/m2), then multiplied by the stem length (m).;Kl; Measure of the efficiency of water flow through a stem segment, normalised to the total leaf area distil to the stem segment. It is calculated as the ratio of the water flow rate (kg/s) to the water potential gradient across the stem segment (MPa), divided by the total leaf area (1/m2), then multiplied by the stem length (m).
Additional comments: This trait is a variant of sapwood specific conductivity normalised to leaf area, usually by multiple Ks (sapwood specific conductivity) by Huber value. It is not a measure of conductivity through a leaf.
units: 10^4.kg/m/MPa/s
allowable range: 0.1 - 500 10^4.kg/m/MPa/s
