Variability studies in sixteen provenances of Acacia mangium Wild for seed morphology, germination behaviour and seedling growth traits were undertaken at the Institute of Forest Genetics and Tree Breeding, Coimbatore, India. The provenances were collected from natural distribution ranges in PNG, Queensland, Philippines, Vietnam, first and second-generation seed orchards in India. Significant differences were observed between the seed lots with respect to seed morphology, germination characters and growth parameters of seedlings. Significant strong positive correlation exists between the seed morphological parameters with germination attributes and seedlings growth attributes such as seedling height, shoot length, root length, basal diameter and number of leaves have recorded strong positive correlation with vigor index. The study concludes that provenance variation contributes largely to seed morphological variations and seedling growth attributes in Acacia mangium.
