Abstract
Exposure to constant 7.2°C temperature and 540 lux incandescent light for 6 weeks induced flowering in rooted cuttings of ‘Lavender Grand Slam’ pelargonium in small peat or clay pots. Total production time from the beginning of propagation to full bloom with this method of flower induction is 15 to 18 weeks. Artificially-imposed low-temperature treatment makes it feasible to grow pelargoniums as a flowering pot plant on a year-around basis.Keywords
