Abstract

The character of the interaction of radiation with the elements of plant canopies determines the light conditions for their photosynthesis and hence for the formation of the final yield. Investigation of the dependence of the optical properties of canopies on the irradiation conditions makes it necessary to know the variability of the optical properties of both individual phytoelements and whole canopies. If the distribution of radiation within a canopy and the character of transformation of the spectral composition of the radiation penetrating the canopy are known, the efficiency of assimilation of radiant energy can be more accurately estimated. Obtaining such information may be helpful in selecting optimum radiation conditions for canopies of a different structure. This paper examines certain optical characteristics of canopies having different optical densities and their individual phytoelements as well as several characteristics of the radiation field in canopies during their prolonged growth while illuminated with radiant fluxes of different intensities and spectral compositions of photosynthetically active radiation.
