Propagation of Black Locust Clones by Treating Hardwood Cuttings with Growth Substances
The retirement from cultivation of large acreages of eroded farm lands has required extensive use of many kinds of woody perennials to conserve the soil. This program has created an interest in improving the economic quality of these plants through superior clonal selections, in order to supplement the farm income under the revised farm management plans. Planting stock of the superior strains and varieties usually does not reproduce true from seed but must be propagated asexually. Recent discoveries in plant propagation methods open the way to developing low-cost production of planting stock from cuttings of woody plants, thus permitting extensive use of clonal selections of many plant species important in erosion control. The black locust (Robinia pseudoacacia L.) is an important species in this program. Exploratory studies now in progress have disclosed a number of apparently distinct strains, some of which possess qualities which surpass the ordinary run of this species in one respect or another. The superior strains may be grown by hardwood cuttings treated according to a procedure which promises to be applicable to quantity production.
