Flower senescence
WebAug 12, 2011 · Introduction. The senescence of many flowers is controlled by the plant hormone ethylene. The induction and production of ethylene vary during the development of the flower, but its effect, as a trigger of flower senescence, occurs during full anthesis (Manning, 1985; Peiser, 1986; Woodson et al., 1992).Studies of ethylene biosynthetic … WebJul 13, 2024 · The cut carnation flowers were exposed to ethylene for 10 h, and the changes in senescence pattern, flower opening, vase life, and water relations were measured during the vase period. Flower senescence symptoms that ended the longevity were BR and WI in the LS group, whereas these were mostly BL and WI in the HS group …
