The portion of a plant or cultivar that is grafted onto a separate rootstock, consisting of a piece of shoot with dormant buds that will produce the stem and branches.

The portion of a plant used to provide the root system and sometimes the lower part of the stem for a grafted plant.

Plumeria Latex as found in nature is a milky fluid also found in 10% of all flowering plants (angiosperms). It is a complex emulsion consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums that coagulate on exposure to air.

When propagating plumeria using a cutting, it is often helpful to use a root-stimulating hormone. Rooting hormone will increase the chance of successful plumeria rooting in most cases. When rooting hormones are used, the callus and the root will generally develop quicker and be of higher quality than when plant-rooting

Plant callus (plural calluses or calli) is a growing mass of unorganized plant parenchyma cells. In living plants, callus cells are those cells that cover a plant wound. The culture medium is supplemented with plant growth regulators, such as auxins, cytokinins, and gibberellins, to initiate callus formation or somatic embryogenesis.
