Abstract
The aim of this study was to characterize sago palm leaves at different phenological stages. Eleven palms representing the entire life cycle of sago palm were selected from local gardens in West Kalimantan, Indonesia. Length of leaf, number of leaves, and number of leaflets for each unfolded leaf were measured. The results showed that sago palm carried maximum leaves in and around the bolting stage. The average leaf length and the number of leaflets were relatively high around the late trunk-formation stage. The generalization of these characteristics into equations should facilitate their integration into the crop simulation model in order to estimate the leaf area index (LAI) or specific leaf area (SLA) more simply.
