Term Definition
Self-pollination

Transfer of pollen (pollination) from the anther of a flower to the stigma of the same flower or sometimes to that of a genetically identical flower (as of the same plant or clone) The ability of many plant species to naturally and successfully fertilize within one individual. Also called Autogamy.

Selfing

To fertilize by means of pollen from the same plant.

Sequence-Related Amplified Polymorphism

A molecular marker technique that targets subsets of open reading frames from coding sequences in the genome.

Sequence-Specific Amplified Polymorphism

A dominant multiplex marker system for the detection of variation in DNA flanking a retrotransposon insertion site

Sequential germination test

A series of discrete seed tests in which the decision to further test seeds or stop the test depends upon the cumulative result.

Sexual reproduction

The production of new individuals
