Abstract In extracts from rose petals cytokinin activity was detected by Amaranthus bioassay in HPLC eluates corresponding to the standards: Z, ZR, 2iP and 2iPA; subsequently, the presence of two groups of endogenous cytokinins was confirmed by ELISA. Measurements of senesence indicators (cell sap osmolarity and conductivity) and observations of flower vase-life indicated that when the above cytokinins were applied as holding solutions they delayed flower senescence by 34–56% and prolonged rose longevity.
