Definition - What does Stamen mean?
The stamen is the male reproductive element of a plant that produces pollen. It is comprised of the anther(s) where the pollen is made and the filament(s), sometimes referred to as a “stalks” that hold up the anthers. Stamens have no petals, only sepals, which is helpful to know when trying to identify the flower’s sex. When the male plant if mature enough, it will produce and release pollen from the stamen which is easily spread by wind, rain and insects. Male cannabis plants are needed when creating new cannabis hybrids, otherwise they are typically culled from a cannabis crop so as not to pollinate female plants.
Hydrolife explains Stamen
Cannabis plants are dioecious, meaning that there are separate male and female plants. Hermaphrodites do occur, but typically plants are either male (with stamen) or female (with pistils), except for propagation by cloning. Female plants are harvested for their buds and most growers only produce female cannabis plants. Breeders, however need male cannabis plants to produce pollen if seed production is desired. Growers can distinguish between male and female plants as the stamen will begin to develop between four and six weeks into the growth cycle. Male plants also produce terpenes and some amount of cannabinoids, though not nearly as much as the female cannabis plants do.
