Cold stored cut spikes influenced by different storage techniques in rose CVs. Bordeaux, poison and avalanche

Abstract

To evaluate best storage technology, an experiment was conducted on post-harvest studies in rose cv. Bordeaux, Poison and Avalanche. Rose cut flowers were cold stored (at 2°C) techniques comprising of seal packaging of cut spikes with HDPE, LDPE, PP (polypropylene) and without packaging and rose flower cut stems kept in water, Al2(SO4)3 200 ppm and citric acid 200 ppm solutions to study flower quality and vase life Cvs., Bordeaux, Poison and Avalanche for the storage period of 10 days. The 10 days cold stored rose cut flowers were compared with fresh flowers during vase life for different parameters. All three packaging films viz., HDPE, LDPE and PP showed promising results in maintaining flower quality and recorded significantly higher water uptake after 10 days of cold storage at 2 °C compared to other storage techniques and fresh flowers. Rose cut spikes packed with PP packaging and stored at 2 °C recorded higher retention of fresh weight, membrane stability index, total soluble sugar content, protein content, anthocyanin content, CAT activity and POX activity during vase life as compared to other storage techniques in the study. Rose cut spikes held in different vase solution during low temperature storage showed advanced flower stage with decrease in vase life upon removal from low temperature storage after 10 days of storage. Thus PP packed cold stored rose flowers retained best flower quality as well as showed higher vase life as compared to the rose flowers stored with other treatments.
