Interacting auxin, gibberellin and cytokinin signals control flower, fruit and seed development.
Gibberellin and auxin trigger fruit set; ethylene triggers ripening; ABA and GA balance seed dormancy. Parthenocarpic (seedless) fruits form with applied hormones.
Hormone balance determines flowering time, fruit set and seed maturation. Commercial use includes fruit thinning and ripening.
Key idea: plant reproduction depends on interacting hormones.
