Abstract: 1. French marigold, cultivar Butter Ball produced no flowers under long day (continuous illumination or 18 hours) conditions at 30°C, but did produce a high percentage of flowering under short day (10h) conditions at the same temperature. However, there was a slight difference in the flowering percentages between the long day and the short day lots at 20°C. Combinations of day length and temperature caused no marked differences in flowering of African marigold.2. Under conditions where the light intensity was reduced to below about 50% of full sun light, anthesis did not occur in the long day (16h) lot, while normal flowers developed in the short day (10h) lot. Natually, the more the light was reduced the fewer flowers were produced.3. Gibberellic acid slightly enhanced flowering of French marigold, while TIBA had no influence.
