Now, scientists claim that they have found a solution-a simple spray that can make the stems look as fresh as they were cut.
It’s dazzling and messy, but it doesn’t take long: the bouquet from the flower shop on the day of purchase looks beautiful, but the beauty quickly disappears
Researchers have found that spraying a solution containing thiazolone or TDZ can make leaves and petals look fresh and healthy longer than usual.
The chemical may have a wide-ranging impact on the florist industry and provide a higher price-performance ratio for millions of consumers.
The research commissioned by the U.S. Department of Agricultural Research, Education and Economics will also help keep potted plants in peak conditions for longer periods of time.
Preliminary research on cut flowers is the first to prove the value of this synthetic compound, and the latest research is the first to show its effect on potted plants to enhance flowering.
These bundles promise to stay as fresh as they were purchased without having to water them within three years.
The longevity of roses is due to a secret preservation process, which means that they do not require water or nutrients.
This process takes away the natural smell and color of the bouquet, but the flowers are offset by the strong rose perfume, and the flowers are colored by edible dyes. A secret technique keeps water in the petals.
Dr. Jiang Caizhong, a plant physiologist at the University of California who conducted the new research, described the “spectacular” way the compound makes flowers and plants look fresh.
He said: “Spraying low concentrations of thiazolone compounds has a significant and sometimes even amazing effect on extending the life of potted plants’ leaves and flowers.
“For example, in tests on cyclamen plants grown in greenhouses, TDZ-treated plants had a longer lifespan than unsprayed plants.
The leaves of TDZ-treated cyclamen plants took longer to turn yellow and fall off than untreated plants.
“Our deeper interest lies in precisely determining how TDZ affects genes and proteins in plants.”
