WebSelf-incompatibility (SI) refers to all genetic mechanisms in flowering plants that prevent self-fertilization through the recognition and rejection of self-pollen by the style of a flower ( DeNettancourt, 1977 ). SI is generally classified into two types: heteromorphic and homomorphic SI. WebThe main features of self incompatibility are briefly presented below: i.
