A MODEL TO SIMULATE THE RADIATIVE TRANSFER OF FLUORESCENCE IN A LEAF

Light is reflected, transmitted and absorbed by green leaves.Chlorophyll fluorescence (ChlF) is the signal emitted Ice and Water Dispensers by chlorophyll molecules in the leaf after the absorption of light.ChlF can be used as a direct probe of the functional status of photosynthetic machinery because of its close relationship with photosynthesis.The scattering, absorbing, and emitting properties of leaves are spectrally dependent, which can be simulated by modeling leaf-level fluorescence.

In this paper, we proposed a Monte-Carlo (MC) model to simulate the radiative transfer of Button photons in the leaf.Results show that typical leaf fluorescence spectra can be properly simulated, with two peaks centered at around 685 nm in the red and 740 nm in the far-red regions.By analysing the sensitivity of the input parameters, we found the MC model can well simulate their influence on the emitted fluorescence.Meanwhile we compared results simulated by MC model with those by the Fluspect model.

Generally they agree well in the far-red region but deviate in the red region.
