Hermaphroditism

Hermaphroditism in cannabis refers to the expression of both male and female reproductive organs on a single plant, rather than a terpene profile trait. This occurs when plants exhibit intersex characteristics—typically staminate flowers alongside pistillate flowers—due to genetic predisposition, environmental stress (heat, light cycle disruption, nutrient imbalance), or deliberate breeding selection. Hermaphroditic plants can self-pollinate, producing seed without a separate male plant. This trait is significant in breeding because uncontrolled hermaphroditism can contaminate seed crops or feminized lines, while controlled expression is leveraged by breeders developing stable feminized seed through colloidal silver or gibberellic acid protocols.

Breeders carefully manage hermaphroditism to prevent accidental pollination in seedless (sinsemilla) cultivation, yet deliberately select for herma traits in parent lines when creating feminized seed stocks. Understanding genetic predisposition to hermaphroditism helps breeders stabilize cultivars for commercial consistency.
