Abstract

With a view to characterizing the rattan resources in Andaman and Nicobar Islands, selected physical and mechanical properties were studied in 10 species comprising 3 genera, viz. Calamus, Daemonorops and Korthalsia. They can be conveniently considered under the three diameter and strength classes proposed for Indian rattans. Of the 10 species, Calamus longisetus, C. pseudorivalis and Daemonorops kurziana were the strongest rattans falling into strength class I (MOR70 N mm-2) . Calamus palustris was the weakest, strength class III (MOR45 N mm-2) . The rest were in strength class II (MOR 45-70 N mm-2) . Generally, the maximum compressive strength (MCS) parallel to the grain was lower than half the value of MOR. Specific gravity, MOR. MOE and MCS were interrelated in the majority of species and decreased from the bottom to the top of the stem
