title: Role of ethylene in distribution of assimilates in cut carnations.
abstract: Distribution patterns of assimilates were studied during senescence in cut carnation flowers pretreated with water or with the flower preservative and anti-ethylene agent, silver thiosulphate. Within the first 5 days after harvest a substantial translocation of assimilates to petals was observed, which ended simultaneously with wilting of the petals. Silver thiosulphate pretreatment prevented wilting and caused a continuous translocation towards the petals. Such a pretreatment caused a decrease in the translocation of assimilates to the pistil, which in water controls continued to accumulate radioactive assimilates during post-harvest life. The interaction between ethylene and assimilate translocation in cut carnation flowers is discussed.
