New method multiplies by ten the smell of flowers

Scientists at the Hebrew University of Jerusalem have come up with a way to genetically enhance the perfume of flowers, and to implant aromas in those species that lack scent.

The perfume of flowers has been multiplied by ten, and it has also been achieved that they emit their scent day and night, regardless of the natural rhythm of production of floral scents.

The flower industry has already shown interest in this method, because many flowers lose their scent after several years of cultivation. With this solution, flowers with growing odors could be created, as well as producing new odors in different flowers.

The laboratory of the director of this research, Alexander Vainstein, is the only one in the world that studies both the color and the smell of flowers. His greenhouse at the Hebrew University is filled with genetically engineered plants whose structure, color and scent the researchers are trying to alter. A previous achievement of this same team consisted of introducing the aroma of flowers in foods such as bread or wine, thanks to components of yeasts.
