    Abstract

    ABA levels in the sprout, the basal plate, the two inner and the two outer bulb scales were determined, both at 5°C (special precooling) as at 17°C (controls). ABA levels, expressed as nmol.g-1 DW, declined slowly but continuously in the basal plate and the two inner and two outer bulb scales. In the sprout an initial decrease in ABA was observed, whereafter the level remained similar. No differences between 5°C and 17°C were observed, until the end of November. From that moment on, a sharp increase in the scales of bulbs stored at 5°C was found. As both bulbs of which the precooling had already been completed before that time, and bulbs of which the precooling was only completed around January showed proper growth and flowering, it was concluded that the ABA levels in these organs had no relation to growth or flowering.
