Abstract:
The preservative effect of TDZ pulse treatment on cut flower of ‘Sorbonne’ lily were studied，the cut flower life, maximal diameter of flower，change rate of fresh weight，chlorophyll content，flower respiration rate and ethylene production were determined. The results showed that appropriate concentration of TDZ pulse treatment had significant effect on preservation of ‘Sorbonne’ lily cut flower，especially 100 μmol/L TDZ pulse treatment.Compare to control，100 μmol/L TDZ pulse treatment could extend the vase life of flowers by up to 1.2 d，and make the maximal diameter of flower increased by 1.56 cm as well as delay the forming time by 1.6 d.Furthermore，the change rate of fresh weight overtopped the control by 10.12%.Besides，the cut flowers pulsing with 100 μmol/L TDZ could maintain a higher level chlorophyll content for a period with a rising trend，and the peak of respiration and ethene release were postponed by 2 d，breathing peak lower 0.53 times than control,ethylene release peak lower 2.39 times than control.
