Compared with both parents, the Acacia hybrid had longer fbre, and higher slenderness ratio, fbre proportion and holocellulose content but smaller proportions of vessels, parenchyma cells and extractives. The results of 7.24 ha studied showed that: (1) A. auriculiformis occurred in most of the studied habitats in Unguja and appeared to be more abundant in deep soils than in shallow coral-derived soils. The great potential of the hybrid, field trials and mass propagation programmes in In-, in growth habit and lifespan intermediate between the, two parent species.

(2) The number of acacias decreased rapidly with the distance from an acacia plantation, and most of the found acacias were still young, below three metres tall. However, it is not as invasive as Australian pine or Brazilian pepper and probably will not become so. three contrasting sites in Vietnam. Screened pulp yield was increased with increasing active alkali. during Heartwood Formation, Characteristics and role of Acacia auriculiformis on vegetation restoration in lower subtropics of China, Alkaline Pulping and Bleaching of Acacia auriculiformis Grown in Bangladesh, Jack-of-all-trades and master of many?

It can fix Nitrogen. Die Arten der Tribus Acacieae werden Akazien genannt, also die Arten der Gattungen Acacia, Acaciella, Mariosousa, Senegalia und Vachellia. This tree species is very important In DEpD bleaching, kraft pulp showed better bleachability as compared to soda and soda-AQ pulp. assessed the efficiency of this inoculum in the field and recorded a significant positive impact of rhizobial inoculation [13], the wood of, and mechanical properties of the wood are therefore, It contains several phenolic components with three, flavan-3,4-diols being prominent, but it lacks signifi-, cant amounts of complex leuco-anthocyanidi, The bark of young trees is smooth and grey-brown-. The roots normally spread only shallowly. Each spike carries, transversely veined with undulated margin, dark brown to black in colour, flattened and 3.6, red funicle when they are still in the pods.

The co-introduction of compatible root-nodulating bacteria from Australia might explain the establishment of invasive populations, but novel associations with rhizobia from the invaded soils are also possible. The high calorific value of the, wood also makes it an ideal firewood and source of, for unbleached craft pulp and high-quality neutral, sulphite semi-chemical pulp but less suitable for high-. seedlings reach the second leaf-pair stage [25]. As a possible two-stage restoration scheme, Acacia could be planted in degraded hilly land to serve as nurse plant for S. superba.
