Some plant populations have low seed production, even when plenty of compatible pollen is supplied. Perennial species tend to have lower fertility than annuals, and outbreeders than inbreeders. The differences show up both in the proportion of flowers that produce fruits, and in the fraction of the ovules in those flowers that form seeds. Possible evolutionary explanations for low female fertility must be consistent with these observed patterns. One hypothesis is that low female fertility has… CONTINUE READING
