ut are now growing in a normal upright fashion. Two others show plagiotropism. All have formed phyllodes, but all are so far much less vigorous than seedling trees growing in the same area. Clonal variation The percentage of rooting of cuttings and air layers indi- cates a possible pronounced clonal variation in rootability (Table 5). These data are only for rooting, not for ultimate survival of the propagules and are, of course, strongly weighted by the variation in numbers of cuttings worked. Only those trees that produced propagative material were listed. Six trees-- numbers 1, 10, 18, 19, 20, and 22--provided a fair size sample of material which did not root. They can be compared with the quite good rooting performance of material from trees 2, 8, 9, 15, and 26. These results are only indicative of possible differences. They cannot be validly compared statistically because of the differences in conditions at each attempt in rooting. Since these data were obtained, we have started more than 100 cuttings from tree number 2 of which 10 to 12 will survive. The key to success in all this propagation work is to use large amounts of material, and this has proved to be impossible with the superior trees up to now. CONCLUSION Acacia koa can be propagated by air layering or rooting of cuttings under mist. However, neither procedure has yet been developed sufficiently so that it can be considered a practical method of propagating forest-grown superior trees. So far only a few propagules of such trees have been produced, and many of them are showing slow growth, disease susceptibility, plagiotropism, or poor form. The only practical way of propagating the species is from seed. This has several obvious disadvantages for tree improvement. Few seeds are produced by the tall, well-formed superior trees which have crowns above the general forest canopy where they are subjected to strong winds and, probably, low populations of insect pollinators. The seeds are open pollinated, so progeny expresses only a portion of the genotype. Most of our tree improvement work with koa will be concen- trated on seedlings. We are gradually building up a supply of sufficient superior tree seed to do a progeny test which w i l l become a future seed orchard. We can also collect seedlings from beneath the trees to transplant to progeny tests.
We are continuing to explore ways of improving vegetative propagation of the species. The latest technique we are trying is to air-layer root suckers in the field and then bring them in as cuttings to root under mist once swelling has occurred above the girdle. This works well with southern hardwoods, but our trials of the method are not yet far enough along to report on. LITERATURE CITED Hartmann, H. T., and D. E. Kester. 1975.
