Abstract:
The diamines putrescine and cadaverine and the polyamines spermine and spermidine inhibited the senescence of nonphotosynthetic cultures of Paul's Scarlet rose. Response was observed when the media of stationary phase cultures was adjusted to either 1 mM of cadaverine or putrescine; or 0.1 μM of either spermine or spermidine along with 2% sucrose in all cases. Senescence of the cultures was followed by microscopic examination of cell aliquots removed at 10 day intervals and treated with the vital stain, fluorescein diacetate.
