Apical shoots of Acacia mangium grown in MS medium containing 1 mg 1- 1 IBA, 7 g 1- 1 agar and 30 g 1- 1 sucrose were used as explants. It is a fast growing, hardy and pioneering plant with nitrifying potential, which makes it suitable for degraded area recovering [ 10 ]. On the abaxial side of the basal part of every leaf stalks of Acacia mangium there are special nectar producing glands, called nectaries. Acacias have a surprising tenant on their branches! Fabaceae.The most common known type is the African type, know as the Bullhorn acacia with large pinnately compound leaves,purple thorns, and a classic shape.But there are many other acacias that have pretty golden yellow flowers, banana like leaves, and Fusilli pasta like fruits! In this study, measurements were made on the leaf water potential (psi1), stomatal conductance (g(s)), transpiration rate, leaf area index, and sapwood area of mature Acacia mangium, aimed to understand the relationships of the leaf hydraulic conductance (K1) with the leaf water use and photosynthetic characteristics of the A. mangium in wet season (May) and dry season (November). A. mangium was characterised by the presence of the 3-glucoside of quercetin, quercetin-3-diglucoside in addition to kaempferol-3,7-dirhamnoside and kaempferol-7,4’-digalactoside.

It is also hybridized with earpod wattle (A. auriculiformis) to form another plantation species. Rooting capacity of microshoots derived from a mature clone of Acacia mangium Willd. Leaf yellowing symptoms were observed on Acacia mangium in the Sipahijala district of Tripura, India, during June 2017. The specific name is an allusion to Rumphius' observation that this tree resembled 'mangge' or mangroves in Indonesia.

This is a list of Acacia species (sensu lato) that are known to contain psychoactive alkaloids, or are suspected of containing such alkaloids due to being psychoactive.The presence and constitution of alkaloids in nature can be highly variable, due to environmental and genetic factors. Abstract.

Tham (1976) documented that A. Mangium and A. auriculiformis can cross pollinate naturally resulting in a hybrid that grows much faster than that of its parent trees. Some species of Acacia include psychoactive alkaloid in the leaves, seed pods, flowers, or stems.
