evidence: Self-incompatibility -LRB- SI -RRB- is a general name for several genetic mechanisms in angiosperms , which prevent self-fertilization and thus encourage outcrossing and allogamy .. angiosperms. angiosperms. self-fertilization. self-fertilization. outcrossing. outcrossing. allogamy. allogamy. fertilization. fertilization. It should not be confused with genetically controlled physical or temporal mechanisms that prevent self-pollination , such as heterostyly and sequential hermaphroditism -LRB- dichogamy -RRB- .. heterostyly. heterostyly. sequential hermaphroditism. sequential hermaphroditism. In plants with SI , when a pollen grain produced in a plant reaches a stigma of the same plant or another plant with a similar genotype , the process of pollen germination , pollen-tube growth , ovule fertilization and embryo development is halted at one of its stages and consequently no seeds are produced .. pollen. pollen. germination. germination. ovule. ovule. fertilization. fertilization. embryo. embryo. genotype. genotype. plant. plant. SI is one of the most important means of preventing inbreeding and promoting the generation of new genotypes in plants , and it is considered as one of the causes for the spread and success of angiosperms on the earth .. angiosperms. angiosperms. inbreeding. inbreeding
