Comparative Analysis of Morphological Traits of Dalbergia sissoo in Forested and Non-forested Areas of Bilaspur, Chhattisgarh, India

Abstract

This study presents a comparative analysis of the morphological traits of Dalbergia sissoo (Indian Rosewood) in forested and non-forested areas of Bilaspur, Chhattisgarh, India. Key parameters including tree height, stem diameter at breast height (DBH), crown diameter, leaf morphology, seed and pod characteristics, and bark features were examined to assess phenotypic diversity and ecological adaptability. Data were collected using field-based measurements and qualitative observations across selected sites.The results revealed that trees in forested areas exhibited greater average height (20.4 m) and DBH (~100.2 cm) compared to those in non-forested sites (average height 17.8 m; DBH ~95 cm). Crown diameters ranged between 8–12 m, with forested populations showing relatively wider canopy spread. Leaf morphology was consistent across both environments, characterized by odd pinnately compound leaves with dark green coloration. Pods were elongated (5–8 cm) and matured from green to dark brown, while seeds were uniformly oval-shaped. Bark in both environments showed a rough, grayish-brown texture with lenticels, indicating adaptability to varying ecological pressures.These findings highlight the morphological variability and adaptability of D. sissoo across different habitats, underscoring its ecological plasticity and potential for sustainable management in both natural forests and agroforestry systems. The study provides baseline data that can guide conservation strategies, plantation programs, and future ecological and genetic research on this economically and ecologically significant species.
