Effect of spermine, spermidine and putrescine on vase life and associated param-eters in two gladiolus cultivars

Various concentrations of pliyamines like spermine, spermidine and putrescine were applied alone or in combination with sucrose in vase solution to study their effect on the vase life and other associated parameters in gladiolus. All the three poiyamines at 100ppm concentration in combination with sucrose were effective in extending vase life of gladiolus. Of these three, 100 ppm spermine along with sucrose in vase solution was also.able to keep fresh weight of gladiolus spikes higher for longer duration in comparison to other treatments due to higher uptake of holding solution. Aesthetic look of cut spikes in terms of floret diameter, turgidity and freshness was also better in this treatment.
