Propagate New Plants from Cuttings and Improve Transplanting. Rose growers may have several varieties that are favorites. From these favorites there may be some which are desirable to propagate for new plants. Some rose may be older varieties which are no longer commercially available. Propagating roses by rooting softwood cuttings is a simple way to obtain more plants.
Some varieties are usually self-rooted.
Modern hybrid teas and floribundas are less predictable. First root the rootstocks from cuttings then perform the budding or grafting operations. Initial callus formation appears to develop about equally on the cut surfaces of both partners, arising not from the cambial layers but from parenchyma cells, mostly in the wood just inside the camblum. Soon after scion and stock calluses have merged, callus cells just below the cambial cells of the scion begin to divide in the same plane as the camblum. Waves of cell division proceed from the top down, suggesting that a regulatory stimulus moves to the cut surface from the growing-shoot tip.
