  • Female fertility in flowering plants is commonly observed to be submaximal. The fraction of ovules in a flower that produce seeds is commonly less than 1.00, particularly in outcrossing species. Here we investigate through controlled pollinations factors that may contribute toward low seed:ovule ratios in Trillium grandiflorum, a self‐incompatible woodland herb from eastern North America. Reduced fruit and seed set in open‐pollinated plants in comparison with hand cross‐pollinated plants… CONTINUE READING
