Phylogeny does not predict the outcome of heterospecific pollen–pistil interactions in a species-rich alpine plant community

Abstract

Our results show that even in communities where HPT is common, pre-zygotic post-pollination mechanisms do not provide strong barriers to interspecific fertilization. HPT can result in the loss of ovules even between highly diverged plant species.
