  abstract = {{T}he stomatal response to air humidity has been recently reinterpreted in the sense that stomata seem to respond to the rate of transpiration rather to air humidity per se. {M}onteith suggested that the relation between canopy stomatal resistance r(s) and canopy transpiration {E} can be written as r(s)/r(sn) = 1/(1-{E}/{E}(x)), where r(sn) is a notional minimum canopy resistance, obtained by extrapolation to zero transpiration, and {E}(x) is a notional maximum transpiration rate, obtained by extrapolation to infinite resistance. {T}he exact significance and possible values of these parameters have not been specified yet. {I}n this study we show that this apparently new relation can be inferred from the common {J}arvis-type models, in which canopy stomatal resistance is expressed in the form of a minimal resistance multiplied by a product of independent stress functions (each one representing the influence of one factor). {T}his is made possible by replacing leaf water potential in the corresponding stress function by its dependence on transpiration and soil water potential. {T}he matching of the two formulations ({M}onteith and {J}arvis) allows one to express the two parameters r(sn) and {E}(x) in terms of the functions and parameters making up the {J}arvis-type models ; r(sn) appears to depend upon solar radiation and soil water potential : it represents the canopy stomatal resistance when the leaf water potential is equal to the soil water potential, all other conditions being equal. {E}(x) depends upon soil water potential and represents the maximum flux of water which can be extracted from the soil by the canopy.
