- Title
TULIP BREAK IN 'PRIDE OF HAARLEM'
- Authors
Bond, T. E. T.
- Abstract
This article describes the symptoms of tulip break in a stock of Pride of Haarlem Darwin tulips in Bristol, England that were recorded from 1950 to 1958. In many varieties of tulip, the two forms of break include a self or dark break involving a localized intensification in the anthocyanin coloration, and a light or full break involving its destruction. In each year, a count was made of the number of blooms exhibiting each degree of breaking as defined by the above key. The average grading for flower break rose from 2.6 in 1950 to a maximum of 3.6 in 1953. Lines in which grade 5 was reached tended to die out within a few years, whereas the stock as a whole increased about ten times.
