Plasma treatment keeps cut flowers fresher for two weeks without chemicals

Phys · · 365 words · By Griffith University
Environmental Sustainability Scientific Innovation

Researchers at Griffith University have conducted an experiment using atmospheric plasma to extend the freshness of cut roses, gerberas, and dahlias. The study suggests that this chemical-free method can maintain flower integrity for up to two weeks, offering a potentially more sustainable alternative to traditional preservatives.
