Sucrose: patterns of uptake and some effects on cut flower senescence


, : Sucrose: patterns of uptake and some effects on cut flower senescence. Acta Horticulturae (41): 45-56

Movement of 14C was studied in cut roses and carnations using a pulse of 14C-sucrose and a distilled water chase. The label moved selectively to leaves and stems, but not to flower heads during the pulse. During the chase, however, 14C moved from leaves and stems into the flower heads. Age had no effect on this movement into rose flower heads, but movement of 14C into carnation flower heads diminished as cut carnations aged.

Nitric oxide (NO*) is an endogenously produced highly bioactive molecule in plants. It has been suggested that NO* acts as a natural senescence-delaying growth regulator and a part of its action are mediated via ethylene metabolism. Therefore, NO*...

All treatments delayed the climacteric peak, those treatments containing sucrose delaying it most. Hydroxyquinoline cit...
