A callus (pl.: calluses) is an area of thickened and sometimes hardened skin that forms as a response to repeated friction, pressure, or other irritation. Since repeated contact is required, calluses are most often found on the feet and hands, but they may occur anywhere on the skin. Some degree of callus, such as on the bottom of the foot, is ...
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. In biological research and biotechnology callus formation is induced from plant tissue samples (explants) after surface sterilization and plating onto tissue culture medium in vitro (in a closed culture vessel such as a Petri ...
Callus is an area of toughened skin. Callus may also refer to: Fibrocartilage callus, the temporary new bony tissue that forms at the ends of a fractured bone; Callus (botany), a fleshy lump of tissue on the labellum (or lip) of orchid flowers; Callus (cell biology), a mass of unorganized cells; Callus (mollusc), a thickened layer of shell material

In vitro and in response to specific cocktails of hormones (mainly auxins and cytokinins), most plant tissues can de-differentiate and form a mass of dividing totipotent stem cells called a callus. Organogenesis can then occur from those cells. The type of organ that is formed depends on the relative concentrations of the hormones in the medium.
Although an excised corn resembles a barleycorn in shape, the two words 'corn' are unrelated. The word 'corn' for a callus derives from the Latin cornus 'horn', and is related to the Greek keras (whence keratin). The 'corn' of 'barley corn' descends from the Indo-European word for 'grain'. The similarity in form is a historical accident.
Let it dry out for several days in a warm, bright spot until a callus forms. Once ready, place the leaf on top of a well-draining potting mix (no need to bury it), water thoroughly, and then let ...
