Plasma treatment keeps cut flowers fresher for two weeks without chemicals
Griffith University researchers have developed a method using atmospheric plasma to keep cut flowers fresh for two weeks without chemicals. The study involved roses, gerberas, and dahlias, which were treated with varying levels of plasma and monitored for freshness. The results indicate that plasma treatment could offer a sustainable alternative to traditional chemical preservatives in the floristry industry.
- ▪The experiment involved treating cut flowers with atmospheric plasma to extend their freshness.
- ▪Plasma-treated flowers maintained their color and freshness over a two-week period.
- ▪This research aims to provide a chemical-free alternative to traditional flower preservatives.
