Nonrandom reproductive success in an endangered evening primrose (Oenothera organensis Munz)

This study examined nonrandom reproductive success in an endangered evening primrose, Oenothera organensis, using an experimental protocol designed to detect nonrandom genetic transmission in all reproductive stages: pollination, fertilization, and seed maturation. Pollination success was monitored in both the native population in New Mexico and experimental arrays of potted plants using fluorescent dye, a pollen analog. Fertilization and seed maturation success was determined by comparing reproductive success in plants transformed with the GUS (...
