Control of branching pattern in Microgramma vacciniifolia, an epiphytic fern.

The rate of expansion of lateral buds of Microgramma vacciniifolia (Langsd. et Fisch) Copeland (Polypodiaceae) does not differ in intact plants, in plants with the rhizome apex removed, and in plants with the apex removed and replaced with indole-acetic acid (IAA). Root elongation is implicated in bud outgrowth possibly through the uptake of water and nutrients.
