Sentence examples for pollination post-pollination from inspiring English sources
This may be explained by incomplete pollination, post-pollination barriers or embryo development problems.
Both the male and female organs of the flower are especially sensitive to temperature fluctuations both during their development before pollination and during the post-pollination stage.
