Daffodil (Narcissus pseudonarcissus L. 'Dutch Master') flowers detached at the base of their ovaries and held with their cut ends in 10-100 microM abscisic acid (ABA) senesced prematurely. Symptoms of the ABA treatment included water-soaking of the tepals and early collapse of the corona. No water-soaking was seen in tepals of flowers held in water. Instead, the tepals of these flowers dried. The ABA content increased in tepals of the potted flowers as they senesced. The rise in tepal ABA… CONTINUE READING
