pullulation

The act of germinating or budding.

Specifically, in botany, a mode of cell-multiplication in which a cell forms a slight protuberance on one side, which afterward increases to the size of the parent-cell, and is cut off from it by the formation of a dividing wall at the narrow point of junction: same as sprouting. This mode of multiplication is especially characteristic of the yeast-plant and its allies.
