The importance of the red-far red antagonism in photoblastic seeds
Acta botanica neerlandica , Volume 19 - Issue 6 p. 809- 812
In white light filtered through leaves the ratio red – far red is strongly shifted to the far red side. Such light prevents germination of photoblastic seeds. Several species of weed seeds were investigated. It is concluded that the spectral composition of the light in a forest must be very important for the density and the composition of the undergrowth.
