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.
This hypothesis is supported by evidence that stilt root palms have earlier vertical stem development than palms without stilt roots, and do so by reducing allocation to belowground roots and developing progressively higher stilt root height (Schatz et al.
We predicted that number of roots, vertical stilt root height, root cone circumference, and overall root cone volume would be greater for individuals on sloped than flat locations.
Vertical stilt root height was measured from the ground to the point of highest stilt root attachment on the stem, and number of roots was counted for each tree.
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.
Number of roots, vertical stilt root height, root cone circumference, and root cone volume demonstrated a whole model effect (Wilks' Lambda, [F.
There was no relationship between the stem height to diameter ratio and stilt root height ([r.
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.
