Abstract:
This study investigates the correlation between key morphological traits and carbon sequestration potential in Candidate Plus Trees (CPTs) of Azadirachta indica (Neem) selected from Jhalawar, Kota, and Baran districts in South-Eastern Rajasthan, India. A total of 90 trees were assessed for girth at breast height (GBH), total tree height, crown diameter, clear bole height, bark thickness, and leaf area. Carbon sequestration was estimated using standard allometric equations suitable for dry climates. Pearson correlation analysis revealed that GBH (r = 0.88, p < 0.01) and total tree height (r = 0.84, p < 0.01) were the strongest positive correlates of CO₂ sequestration. Moderate correlations were observed with crown diameter, clear bole height, and leaf area. The results underscore the significance of specific growth traits in guiding genotype selection for carbon-oriented forestry strategies, especially in semi-arid environments.
