Oscillations in stomatal conductance: the influence of environmental gain.

摘要: It is supposed that oscillations in stomatal conductance are associated with the dynamic properties of loop which rate evaporation affects, through physiological processes, aperture stomata and turn affects evaporation. therefore predicted their occurrence must be influenced by magnitude what termed environmental gain: sensitivity to change leaf vapor transfer. Two methods manipulating gain, effects on behavior cotton (Gossypium hirsutum L. cv. Deltapine Smooth Leaf), described. In first, gain was increased decreasing ambient humidity; second, it made zero regulating humidity keep constant despite changes conductance. The results accord supposition.
