Chitooligosaccharide Prolongs Vase Life of Cut Roses by Decreasing Reactive Oxygen Species

Abstract

Chitooligosaccharide (COS), as antioxidant, extensively applied to food and juice preservation. In the present study, influences of COS on vase life and ornamental value of cut roses were investigated. Results showed that vase life of cut roses treated by COS was longer 6.4 days than one of control and ornamental character of cut roses was improved effectively by COS. The increase of vase life and ornamental value were chiefly governed by that COS improved water absorption capacity of cut roses. Besides that, COS decreased the contents of superoxide anion and hydrogen peroxide and lowered the levels of malondialdehyde in turn during the senescence process of cut roses. That was because that COS not only enhanced activities of antioxidant enzymes glutathione reductase, but also improved reduced glutathione contents in petals of cut rose. Therefore, COS could be used in commercial preservatives to improve the longevity of cut roses.

Eucalyptus and Citronella Essential Oils Used in Preservative Solutions Affect the Vase Life of Cut Philodendron Leaves

“…Chitooligosaccharide also decreased the contents of superoxide anion and hydrogen peroxide during senescence of cut roses (Jing and Li, 2015). Our observations show that philodendron plu jeeb leaves exposed to eucalyptus essential oil had lower H 2 O 2 levels than untreated control leaves (Fig.…”

Chitosan Effects on Plant Systems

“…ex Klatt) led to taller plants, with more leaves, shoots, flowers, and corms [ 90 ]. The vase life of cut rose flowers ( Rosa hybrida L.) “Red France” was also prolonged by CHT [ 91 ]. The largest number of studies on the effects of CHT deal with fruit crops.…”

Effect of Chitosan nanoparticles on quality indices, metabolites, and vase life of Rosa hybrida cv. Black magic

“…Numerous literatures had shown the effect of chitosan on the postharvest quality of flowers. It has also been applied to raise the vase life of cut flower like Heliconia bihai L. [19] and roses [20]. Ali et al [21] demonstrated that applying 1-MCP or CTS-NPs after harvest is a very viable approach for preserving damask rose postharvest quality during storage.…”
