VEGETATIVE PROPAGATION OF STRELITZIA REGINAE *

Acta Horticulturae, 1988
Strelitzia reginae is propagated either by division of naturally developed branches known as fans or by seeds. Vegetative propagation by division is limited by a low rate of multiplication being 0.5–1.5 divisions per branch per year. Branching originates in the division of the apical dome with an absolute abscence of branching from axillary buds ...

Sound propagation through vegetation

Journal of Sound and Vibration, 1982
Abstract The propagation of sound through a large number of scatterers (i.e., trees) is treated in a similar way to a classical diffusion problem. A general differential equation governing the sound intensity is derived which is valid under certain conditions, notably that the depth of the belt of vegetation is large, and absorption small.
