This study was conducted to identify the effects of NaOCl, ClO₂, and Chrysal OVB, which are the solutions used for shipping, on the quality and vase life of chrysanthemum ‘Baekma’ cut flowers. We also aimed to analyze correlations with vase life by analyzing chlorophyll fluorescence and spectral reflectance of cut flowers subjected to dry and wet shipping. Compared to dry shipping, the wet shipping treatments using solutions of NaOCl, ClO₂, and Chrysal OVB resulted in an increase of fresh weight and flower width, with the leaves remaining in fresh states after transport for 4 days. In holding solution, the cut flowers transported with 50 ㎎·L<SUP>-1</SUP> NaOCl had a greater fresh weight and flower diameter as well as a longer vase life of 26 days compared with dry and wet shipping conditions with tap water, ClO₂, and Chrysal OVB solution. The cut flowers treated with wet shipping conditions by NaOCl had lower values of ABS/RC and DIo/RC and higher values of Fm/Fo, Fv/Fo, Fv/Fm, TRo/ABS, ETo/TRo, ETo/ABS, Pi_ABS, and ETo/RC among chlorophyll fluorescence parameters compared to those subjected to dry shipping conditions. Among the parameters, the Fv/Fm and ETo/RC exhibited statistically significant correlations with the vase life of cut flowers. In terms of spectral reflectance, the wet shipping treatment with 50 ㎎·L<SUP>-1</SUP> NaOCl resulted in lower values of CRI, G, MCARI, NPCI, and SIPI that represent the ratio of contents of carotenoid and chlorophyll compared to the dry shipping treatment, whereas SRPI resulted in higher values. Among these parameters, the CRI, SRPI, and NPCI manifested a statistically significant correlation with vase life of cut flowers. Therefore, it was concluded that wet shipping with 50 ㎎·L<SUP>-1</SUP> NaOCl helped maintain quality and vase life of cut flowers of chrysanthemum ‘Baekma’ compared to dry or wet shipping with Chrysal OVB and ClO₂ that were used commercially. In addition, the Fv/Fm and ETo/RC, representing chlorophyll fluorescence, and CRI, SRPI, and NPCI, representing spectral reflectance, were found to be feasible indicators predicting the vase life of cut flowers.
