This study explored the changes in senescence patterns and vase life of cut roses grown in summer and autumn, aiming to identify the relationship between harvest seasons and flower longevity. We analyzed gene expression profiles associated with lignin, pectin, ethylene, auxin, and sucrose transport to understand the molecular mechanisms underlying senescence symptoms, such as the bent neck, petal abscission, and petal wilting in cut rose flowers. Our results revealed season-dependent occurrences of bent neck and petal abscission, with higher incidence rates in autumn-harvested rose flowers. These increases in bent neck and petal abscission contributed to a shortened vase life for the cut flowers. Gene expression analysis indicated that elevated levels of ethylene biosynthesis genes and reduced expression of lignin, pectin biosynthesis, auxin response factor, and sucrose transport genes accelerated the increased senescence symptoms. Notably, the incidence rates of the bent neck were highly negatively correlated with the transcript levels of key genes involved in lignin and pectin biosynthesis, RhPRXPX and RhGAUT1, in pedicels. These findings contribute to our understanding of the molecular factors influencing the mechanical strength of flower pedicels and provide insights for postharvest strategies to enhance the ornamental value of cut flowers across seasons.
