INCIDENCE OF MONOECY AND DICHOGAMY IN RELATION TO SELF‐FERTILIZATION IN ANGIOSPERMS

American Journal of Botany, 1993
The evolution of many floral traits, including monoecy and dichogamy, has been attributed to selection for avoidance of self‐fertilization. If this explanation is correct, monoecy and dichogamy should be uncommon among self‐incompatible species because physiological barriers prevent self‐fertilization in such species.

THE EVOLUTION AND MAINTENANCE OF MONOECY AND DIOECY IN SAGITTARIA LATIFOLIA (ALISMATACEAE)

Evolution; International Journal of Organic Evolution, 2002
Plant species rarely exhibit both monoecious and dioecious sexual systems. This limits opportunities to investigate the consequences of combined versus separate sex function on mating patterns and genetic variation and the analysis of factors responsible for the evolution and maintenance of the two sexual systems.

Sex allocation in plants and the evolution of monoecy

open access: yesEvolutionary Ecology Research, 2008
Question: Which ecological factors favour the transition from perfect flowers to separate male and female flowers on the same individual?Mathematical methods: ESS computation in sex allocation models.Key assumptions: Within a flower, the costs of attraction, pollen production, style/ovary and seed-bearing fruit are assumed to be fixed.
