The influence of light quality on rose flower senescence: involvement of abscisic acid
1995
Garello, G. | Menard, C. Dansereau, B. | Le Page-Degivry, M.T.
The aim of this work was to study the impact of light applied during preharvest culture on the subsequent senescence of cut rose flower and to analyse the possible involvement of abscisic acid (ABA). The longevity of cut rose flowers was longer when rose plants were previously grown under high pressure sodium lamps than under metal halide lamps. A change in light source did not lead to a change in leaf ABA content but significantly affected the petal ABA content. The relationship between ABA level and flower longevity, previously reported for differences of genetic origin, was again observed for culture-induced differences: the higher the ABA level at harvest, the shorter the vase-life observed.
