Description Changes in the concentrations of endogenous
polyamines and ethylene were determined in two diverse
species of rose viz. Rosa damascena and Rosa bourboniana
during post-harvest periods. At full bloom, the concentrations
of free putrescine was significantly higher than rest of
the polyamines, i.e. spermine and spermidine in both the
species. The concentrations of all the polyamines decreased
during subsequent periods upto 48 h after full bloom.
Similar situation was also observed in conjugated fraction
but in bound fraction, during full bloom, the concentration
of spermine was higher than rest of the polyamines. In both
the species, ethylene showed higher levels during full
bloom with maximum in R. damascena, which increased,
during post-harvest periods. The possible significance of
polyamines, ethylene and their interactions is discussed
during post-harvest periods in flowers.
