Abstract

Calamus palustris Griff. is a dioecious rattan species of commercial importance for its canes. The sex of C. palustris can only be identified from the morphology of the inflorescence. In this survey, the sex ratio of C. palustris planted in 2001 in an experimental plot at Universiti Kebangsaan Malaysia, was studied. The survey was conducted from September 2003 to July 2006. A total of 46 male and 43 female plants were identified from the 140 surviving plants in the plot. This gave a ratio of female to male as 1:1.1 with no significant difference compared to an even ratio 1:1. The survival percentage of the planted population was 93.3%. The female plants had 1-7 stems per clump, while the male had 1-10 stems per clump with an average of 4 stems per clump for both the sexes. The even sex ratio of the planted C. palustris population might indicate absence of post zygotic sex selection and unbiased sex selection during seed germination.
