Postharvest handling of Heliconia bihai to preserve freshness

Flowers can evoke sensations linked to nature, freshness, and pleasant environments. In this context, heliconias have become increasingly popular in floristry due to their visual appeal, abundance, and elegance. Therefore, proper postharvest handling is essential to extend their shelf life while preserving their structural characteristics.

The aim of this study was to determine the most suitable solution to enhance water uptake in Bihai flowers (Heliconia bihai L.), reducing wilting and transpiration from harvest through transport, storage, and vase life. Additionally, a packaging proposal for transportation was developed.

The methodology involved applying sucrose, Tween, and BAP solutions at different concentrations for flower hydration. Preservation was then evaluated at room temperature and under refrigeration at 15 °C.

Results indicated that sucrose solution maintained flower freshness for up to 6 days at room temperature. Under refrigerated conditions, Tween solution proved most effective, extending freshness up to 12 days. No significant differences were observed among treatments during vase life.

Regarding packaging, single-wall corrugated cardboard, white on one side with a 26ECT rating, was identified as suitable for transporting these flowers. In conclusion, sucrose is recommended for transport, Tween for cold storage, and any of the tested solutions for vase use.
