Abstract

An investigation was conducted during the period of 2012-14 to study the morphological characters and floral biology of Garcinia species of Assam viz., Garcinia pedunculata Roxb, Garcinia cowa Roxb, Garcinia lanceaefolia Roxb and Garcinia xanthochymus Hook. f. The morphological parameters of plant and floral biology were studied in healthy, bearing trees of uniform age from five locations of Jorhat district viz., Bahek gaon (L1), Charaibahi (L2), Atila gaon (L3), Chotai (L4) and Borbheta (L5). Non significant difference was found in plant height of each species. However, plant height of G. pedunculata is highest (22.40 m) among the four species. Duration of flowering was almost same in all the species and the maximum (52 days) was observed in G. xanthochymus and the minimum (42 days) was recorded in G. Lanceaefolia. Anthesis took place early in the morning in all the species and the time period was from 1.00 A.M. to 6.00 A.M. The morphological as well as floral biology study gives a scope for genetic assessment and breeding due to the presence of variability in different characters.
