L. diversifolia fixes nitrogen with Rhizobium , and has a specificity comparable to that of L. leucocephala. Seeds may take a week to fully germinate, and early growth rates are half that of more vigorous leucaenas. Seedlings are typically transplanted into the field eight to twelve weeks after germination, when they should be 15 to 30 cm tall. Vegetative propagation from cuttings and grafts has generally failed although tissue culture is successful. L. diversifolia are generally resistant to insect pests in the field.
Some diploids are extremely resistant to psyllids.
The best known hybrid is that between tetraploid L. diversifolia and L. leucocephala . It is called 'KX3'. It has a broader genetic base than either parent and often outyields them. Like the parents, the hybrid is self-fertile and seedy. References Bray, RA. and T.D. Woodroffe.
