grafting roses, etc.
I'd like to ask- my grandfather did a lot of grafting, and I would watch him. He used to dip the end of the part he was grafting into some white powdery stuff he got at the nursery. This was in the early 1960's. He told me what it was, but of course, I can't remember. He used this white powder to graft roses, and made beautiful varigated carnations with the same method. Anyone have any idea what the substance was? Thanks, Karen |

Here a website that talks about the use of rooting hormones with grafting.
Hope it helps. I use the powder form, but I think its about the same either way. http://www.rooting-hormones.com/stenting.htm "Cummins (1997) states that the 'success of a graft union depends on the establishment of a callus bridge between the cut surfaces of scion and stock and the subsequent establishment of a functioning vascular cylinder connecting scion and stock. 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 cambium. 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 cambium. Waves of cell division proceed from the top down, suggesting that a regulatory stimulus moves to the cut surface from the growing-shoot tip. Callus parenchyma cells inside the new cambium cylinder re-differentiate into functioning xylem cells. The new cambium begins producing phloem cells.' Upon application of liquid rooting hormones to the graft site, of malus trials, survival was greater for the treated grafts than for those not treated. He used the equivalent of a fresh solution of Rhizopon AA Water Soluble Tablets at 40 tablets per liter (2000 ppm active ingredients). Cummins says it is probable that the rooting hormones increase both the formation of a callus and the rate at which the new cambium cylinder is differentiated through the callus parenchyma cells. He suggests that dry powder rooting hormone should also be tried at the graft union."
