Plant canopy reflectance is calculated using the governing equation for photon transport. The integral equation of transfer is solved by the Monte Carlo method. The main emphasis is on statistical estimation and simulation of the Marcov chain. The leaf dimensions are taken into account in obtaining the hot-spot effect of the canopy. Finally, numerical results for transport equation obtained by the Monte Carlo method are compared with those obtained by using the method of discrete ordinates and the geometrical Monte Carlo model.
