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.
