Cannabis sex determination and sex-expression plasticity, genetic and hormonal regulation, environmental context, hermaphroditism, early detection, and breeding implications.
Visual lesson 01
Male vs female preflowers
Compare developing staminate and pistillate structures at nodes using multiple views and developmental stages.
Interactive academic visual
Male vs female preflowers
Compare developing reproductive structures at nodes across more than one developmental stageInspect the node
Early reproductive structures arise near nodes, so inspect the axil rather than relying on overall plant shape.
