Resumen :
The marketability of cut flowers is directly affected by their vase life, which determines acceptability for commercial
purposes. In carnations and other species of cut flowers, corolla is one of the most affected parts during
flower senescence due to the petal withering which is accelerated by metabolic processes occurring after separation
from the mother plant. Melatonin (MT) is a compound with antioxidant properties, naturally present in
plant tissues that plays important roles in the regulation of different metabolic processes. In this research work
the effect of different MT concentrations (0.01, 0.1 and 1 mM) on the vase life of cut carnations flowers cv.
Baltico was evaluated. The greatest delay in senescence was observed with 0.1 mM MT concentration, increasing
vase life up to 10 days more as compared to control carnations. Although all MT concentrations assayed
significantly (P < 0.05) maintained initial levels of fresh weight, membrane stability index, bioactive compounds
and antioxidant activity for longer time, the lowest concentrations were those that had the most relevant impact
on vase life. The highest dose evaluated (1 mM) maintained all the parameters evaluated but showed the wilting
symptoms earlier. For this reason, 0.1 MT concentration could be a tool capable of improving carnation vase life
for longer time, increasing the commercial potential of this cut flower.
