Sources of variation in plant reproductive success and implications for concepts of sexual selection

There is growing evidence of nonrandom reproductive success in plants. An experimental protocol was designed to yield more information on nonrandom transmission in general and on sexual selection as a special case. Reproduction is separated into pollination, fertilization and seed-maturation phases, in which functional processes associated with the genders are known and in which the genders can be manipulated. Sources of variation in reproductive success are then identified by systematically repeating a reciprocal-crossing design with treatments that alter the intensity with which males and/or females can interact. -from Authors
