Near-surface silica does not increase radiative heat dissipation from plant leaves
Author
Summary, in English
It has been suggested that plants are able to increase radiative heat dissipation from their leaves by depositing near-surface silica, in this way increasing emissivity of infrared radiation and lowering
leaf temperature. In order to test this theory, we have compared emissivity and radiative dissipation over the mid-infrared range 2.5–22.3 lm of leaves of plants that accumulate silica and plants that
do not. Our data do not support the theory that accumulation of silica increases radiative heat dissipation by plant leaves.
