Self-compatibility in peach Prunus persica (L.) Batsch: patterns of diversity surrounding the S-locus and analysis of SFB alleles

摘要

a The flowers of each genotype were collected at the balloon stage, b the pollen grain germination was successful at the surface of stigma in self-pollinated flowers, c pollen tube growth was arrested at the style of self-incompatible plum “Cidre” used as reference, and d the pollen tubes reached the base of the style in peach and self-compatible plum “Bedri” used as reference.
