Cold requirements of tulips for earliest flowering


, : Cold requirements of tulips for earliest flowering. Acta Horticulturae (47): 209-214

Experiments are described where different temperature regimes were applied to forced bulbs of tulip Paul Richter after planting. Fastest flowering followed low initial temperatures followed by high temperatures, and the results are interpreted on the basis of 2 processes, the satisfaction of the cold requirement and shoot extension growth.
