Action spectrum of transpiration is - (d) Blue and red
Action spectrum of transpiration provides the relation between wavelength of light and rate of reaction or activity occuring due to that particular wavelength of light.
Considerable transpiration occurs throught stomatal openings.
Stomatal opening is controlled by light.
Therefore, the light mainly responsible for stomatal opening and hence transpiration is blue and red light.
