GC-MS analysis of active ethanolic (E4) and acetone (A3) fraction extracts from stilt root of R.
This study reveals that the ethanolic extracts of the bark and stilt root of R.
In this study, it has been found that all the extracts showed moderate larvicidal activity and the highest larval mortality was found in acetone and ethanolic fraction of the stilt root and bark extracts of R.
Multivariate Analysis of Variance (MANOVA) was used to analyze differences between flat and sloped locations at La Selva and BCI for number of roots, vertical stilt root height, root cone circumference, and root cone volume.
To examine the relationship between stilt root architecture and stem height, stem diameter was restricted to 12-17.5 cm for all palms sampled.
Number of roots, vertical stilt root height, root cone circumference, and root cone volume demonstrated a whole model effect (Wilks' Lambda, [F.sub.12, 188]=4.97, p<0.001).
It was predicted that palms would alter their architecture with respect to location by adding stilt roots, altering stilt root location, increasing vertical stilt root height, developing a wider structural base via increased root cone circumference, or adding root volume for enhanced physical stability.
A positive relationship was found between the allocation of biomass to vertical growth and stilt root structure.

Stilt roots have been proposed to serve a number of functions including the facilitation of rapid vertical growth to the canopy and enhanced mechanical stability.
