Some Aspects of Light in the Forest

In this present investigation an attempt is made to determine experimentally to what extent light controls the vegetation on the forest floor and, consequently, succession of the forest flora, and whether under natural canopies light can be looked upon as a limiting factor in plant survival. The general conclusion reached is that the intensity and quality of the light reaching the forest floor are not the determining factors in accounting for the presence or absence of reproduction in the fully stocked forest where the investigation was made
