Extending vase life of carnations dianthus caryophyllus cultivar white sim with aminooxy acetic acid poly amines n 2 2 oxo 1 imidazolidinylethyl n' phenyl urea and carbonyl cyanide m chlorophenyl hydrazone


, : Extending vase life of carnations dianthus caryophyllus cultivar white sim with aminooxy acetic acid poly amines n 2 2 oxo 1 imidazolidinylethyl n' phenyl urea and carbonyl cyanide m chlorophenyl hydrazone. Hortscience 15(6 SECT. 1): 805-806

Aminooxyacetic acid (AOAA) at a concentration of 0.5 mM extended the vase life of carnations (D. caryophyllus L. cv. White Sim) to a degree comparable to that shown by 0.1 mM aminoethoxyvinylglycine (AVG, 71-94%). Increases in vase life ranging 22-53% were also obtained with N-[2-(2-oxo-1-imidazolidinyl)ethyl]-N'-phenylurea (EDU), carbonylcyanide m-chlorophenyl-hydrazone (CCCP), spermidine, putrescine or spermine. Combinations of AVG and EDU or AOAA and EDU further extended the vase life 134-140% over that of the control flowers. These increases were additive to the beneficial effects obtained from the control preservative solution, which contained 2% sucrose and 200 ppm 8-hydroxyquinoline citrate.
