Senescence in cut flowers refers to which of the following?

• A. The growth of roots
• B. Color retention during storage
• C. The development of buds
• D. The aging process resulting in wilting and death

Answer: (D)

Senescence is the aging process in cut flowers, and it manifests as wilting, loss of turgor, pigment changes, and eventual death of the flower tissues. This is why the correct choice describes aging and decline rather than growth or development stages or storage color effects. Growth of roots is a developmental process, not the aging of cut flowers. Color retention during storage concerns how pigments hold up, not the natural aging of the flower. Development of buds is a growth stage prior to opening, not the decline that defines senescence. In practice, understanding senescence helps explain vase life and why interventions aim to delay this aging process.
