SENESCENCE-ASSOCIATED GENE EXPRESSION IN NARCISSUS ‘DUTCH MASTER’
Daffodils (Narcissus) are widely grown commercial flowers that are prized for their beauty in spring. The flowers are short-lived and are reported to senesce independently of ethylene action (Woltering and van Doorn, 1988). In addition to the petals and sepals (tepals), daffodil flowers are unique in possessing an additional petaloid structure, the corona. We have used the flowers of the ‘Dutch Master’ cultivar as an experimental model to examine molecular changes associated with the onset of non-climacteric flower senescence, and report here our preliminary results.
