from 51 coconut palms belonging to three age groups viz., 15-25 years (young), 35-
45 years (mature) and 55-65 years (over mature), grown in three agro-climatic
zones (Malayoram, Central midland and Coastal sandy) of Thrissur district, Kerala
were profiled in this study.
Dermal, sub-dermal and core wood from each sample were used for assessing
physical and anatomical properties and samples of density above
650 kg m -3
were selected for profiling mechanical properties. Nested analysis of variance was
carried out to analyse the variation in coconut palm wood properties due to location,
age and radial position.
Most of the physical, anatomical and mechanical properties did not vary
significantly across agro-climatic zones and age groups. However, across age
groups, basic density, vascular bundle percentage, fibre lumen diameter, fibre wall
thickness and compression parallel to grain (maximum load and compressive stress
at maximum load) were found to vary significantly.
Along the radial positions there was significant difference in physical and
anatomical properties.
Basic density, being highly positively correlated with
mechanical and anatomical properties, estimation of density can be used as a key
to determine end use under field conditions for potential utilization at the industrial
level.
