Stomatal responses to humidity in selected conifers
... .5%), and shoots of P. sitchensis the largest reduction (64.6%) in stomatal conductance. However, in no species was stomatal closure sufficient to cause a reduction in transpiration (E) as D increased. Net ... in P. sitchensis it declined. Explanation of these data does not require a mechanism of stomatal closure involving a site that senses the vapor pressure deficit outside the leaf. However, it is ...
