Neoagaro-oligosaccharides Improve the Postharvest Flower Quality and Vase Life of Cut Rose ‘Gaoyuanhong’

Rose is among the most important cut flower crops worldwide. The vase life an indicator of rose quality. composition solution directly affects life. Neoagaro-oligosaccharides (NAOS) are degraded seaweed-derived polysaccharides that constitute a group compounds with small molecular weight and good water solubility. Oligosaccharide treatment can extend postharvest longevity certain types flowers; however, little information available on utility NAOS for preservation flowers. To explore effects quality flowers ‘Gaoyuanhong’, 100 mg·L −1 alone in combination 10 g·L sucrose were incorporated solution. Distilled was used as control. Physiological indicators, comprising maximum diameter, fresh weight, balance, life, bacteria number solution, hormone contents outer petals, determined analyzed. Compared control, increased diameter (mean 8.21 cm), induced rates change maintained best significantly extended to 16 days, reduced abscisic acid content petals control treatments lower than other day 9. results showed useful improve flowers, might contribute development novel alternative preservatives industry.
