In trials where rainfall is relatively high, the Charleville, Queensland provenance, a broad phyllode form, has grown more rapidly than provenances from central Australia (Ryan and Bell 1989).
Its form and phyllode morphology are exceptionally variable (Midgley and Gunn 1985).
Trees with different phyllode forms have been observed to have different growth rates (Fox 1980).
FODDER: The fodder potential is mainly due to the large phyllode biomass produced during the dry season, a period when most non-Australian acacias traditionally used for fodder shed their leaves.
Seedlings are able to switch back from phyllode to true leave production when the sunlight reaching them is reduced.
A. holosericea is perhaps the most frequently planted Australian Acacia in development projects because of its superior yield and because it retains a large phyllode biomass during the dry season, while African species shed their leaves during this period (Cossalter, 1986).
The phyllode has the ability to photosynthesize and for all practical purposes, it is the equivalent of a leaf.
There are 3 prominent longitudinal nerves running together towards the lower margin or in the middle near the base, with many fine crowded secondary nerves, and a distinct gland at the base of the phyllode (Pedley 1978).
Seedlings are able to switch back from phyllode to true leave production when the sunlight reaching them is reduced (Walters and Bartholomew 1990).
In trials where rainfall is relatively high, the Charleville, Queensland provenance a broad phyllode form, has grown more rapidly than provenances from central Australia (Ryan and Bell 1989).
