Spectral transmission curves of some types of leaf canopies with a note on seed germination
Acta botanica neerlandica , Volume 21 - Issue 3 p. 185- 191
Measurements show that dense leaf canopies transmit very little radiation in the wavelengths 400-700 nm and many times as much radiation in the longer wavelengths. It is shown that germination of seeds requiring either light or darkness can be inhibited under a dense canopy but the ecological importance of this phenomenon is not proved.
