H. cannabinus South-Selected seedlings were sensitive to daylength even before expansion of the cotyledons. Seedlings grown in short days or in 10 short days followed by light-break short days all formed flower buds within 16 days but if long days preceeded the short day treatment all were vegetative after 30 days. Use of a neutral daylength of 13 h light/11 h dark showed that seedling age did not cause the difference due to long day treatment.
