Abstract
Apical application of cobalt chloride to female plants (50 or 100 μg/ plant) ofCannabis sativa caused drying of the shoot tip and formation of axillary branches. The latter bore male, reduced male and intersexual flowers, in addition to female flowers. Pollen in the flowers of altered sex were viable.
