Abstract
The effect of vernalization and two growth regulators Fascination™ and Pro-Gibb® on the growth, inflorescence development and flowering of Ornithogalum `Chesapeake Snowflake' was studied. Regardless of bulb size, chilling bulbs for 3 weeks at 10°C before planting accelerated flowering of the first inflorescence and shorten leaf length by 3-5cm as compared to non-chilled bulbs. Fascination™ 10% 100 μL and Pro-Gibb® 200 ppm accelerated flowering of first inflorescence by large bulbs (8- to 10-cm circumference) as compared to controls. PGR treatments appear to have no effect on small bulbs (3-5-cm circumference).
